φ700mm UHP Graphite Electrodes Nipple

φ700mm UHP graphite electrode is used in large volume UHP DC-ARC furnace as high-temperature resistance, electrical conducting graphite materials, which is well-sold in domestic and foreign markets and has a high value because of its high-tech and complicated processing procedure. As now, with the continuous improvement of steelmaking requirements, the production and use of graphite electrodes are developing in the direction of high quality and ultra-high power. Therefore, the produce and usage of φ700mm UHP Graphite Electrodes Nipple are gradually increasing.

Graphite Electrode Nipples — RS Graphite Electrode Nipple

During producing φ700mm UHP graphite electrode, a higher requirement to prepare graphite electrodes nipple is needed because of the nipple as joint bears higher smelting requests. Therefore, the small-scale and middle-scale experiments were carried on in the lab, using high-grade petroleum needle coke X-grade SUMITOMO coke as a skeleton, Tianjin modified pitch as binder, with various process formulas and two additives to investigate the preparing process and producing techniques.

During small-scale experiments, the size distributions of formulas were selected by trying measuring vibrated bulk densities of a lot of mixtures. On the basis of them, 9 experimental formulas were designed and carried out. The suitable formulas were optimized by a polarized light microscope and measured results of samples.

A small-scale experiment shows that some formulas are gained by the method of measuring vibrated bulk density, whose characteristics are intermittent size distribution and continuous size distribution. Samples’ properties based on formulas derived from intermittent size distribution are better than the ones based on formulas derived from continuous size distribution. For example, the bulk density is improved 0.02~0.04 g/cm³, flexural strength is improved 19% ~ 41%，specific electrical resistance is lowered 8% ~ 22%. Compared with middle-temperature coal tar pitch, the modified pitch can apparently improve 0.02 g/cm³ of the bulk density and 10% of the mechanical strength of graphite electrode nipple samples because of 5% higher fixed carbon and binder strength. Stearic acid should be prudently used because it lowers more than 16% mechanical strength of graphite electrodes nipple samples although it could lower the softening point and viscosity of pitch so that it benefits for improving extrusion productivity. Adding proper additives of Fe2O3 could effectively inhabit the puffing in graphitization and improve the mechanical strength of graphite electrodes nipple samples.

On basis of small-scale experiments, selecting proper process formulas, optimizing various procedure parameters, adding procedure of impregnation and re-baking, middle-scale experiments were carried out with polarized light microscope and SEM, according to commercial production.

Results of middle-scale experiments show that increasing the content of fine particles in formulas could improve the mechanical strength of graphite electrodes nipple samples. Especially, increasing the content of ultra-fine particles in formulas could increase more than 10% of the mechanical strength of nipple samples. The procedure of impregnation and re-baking is a good method to improve the mechanical strength of graphite electrode nipple samples. But more times, improving amplitude gets less and less, and make the coefficient of thermal expansion rise.

Properties of final graphite electrodes nipple samples are as follows: bulk density 1.87 g/cm3, flexural strength 29.4MPa, Young’s modulus 17.1 GPa, coefficient of thermal expansion 1.50×10^-6/℃, specific electrical resistance 4.9 μΩm, which are close to those of foreign φ 700mm UHP graphite electrodes nipple.

What are Graphite Electrodes?

What are graphite electrodes? Graphite electrodes are kind of conductive material in electric arc furnace steelmaking production. The graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, and coal pitch is used as a binder, and is made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. Due to some special properties of graphite. It is a conductor that releases electrical energy in the form of an electric arc to heat and melt the charge in the electric arc furnace. According to its quality index, it can be divided into rp graphite electrode, high power graphite electrode and ultra high power graphite electrode.

What are the graphite electrodes?

Rp graphite electrode, produced with ordinary grade petroleum coke. Graphitization temperature is low, its resistivity is high, the coefficient of linear expansion is large, and its thermal shock resistance is poor, so the current density is allowed to be low.

HP graphite electrode, produced with high-quality petroleum coke (or low-grade needle coke). Sometimes the electrode body needs to be dipped. Its physical and mechanical properties are higher than those of ordinary power graphite electrodes, such as low resistivity, which allows a large current density.

UHP graphite electrodes must be produced with high-grade needle coke. And the graphitization heat treatment should be carried out in the internal graphitization furnace. The graphitization temperature is as high as 2800 ~ 3000 ° C. Therefore, the resistivity is lower, allowing greater current density, the linear expansion coefficient is smaller, and has excellent thermal shock resistance.

The main raw material for the production of graphite electrodes is petroleum coke. A small amount of pitch coke can be added to rp graphite electrodes, and the sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also needed when producing high-power or ultra-high-power graphite electrodes. The main raw material for the production of aluminum anodes is petroleum coke, and the sulfur content should be controlled not more than 1.5% to 2%. Petroleum coke and asphalt coke should meet the relevant national quality standards.

Calculation Method of Graphite Electrode Consumption of Electric Arc Furnace Electrode

The graphite electrode consumption in electric furnaces is generally considered to be the third largest in the cost of molten steel after scrap steel and electrical energy. In Europe, the consumption range is 3 to 7 kg / t (crude steel). This article will analyze the main reasons for the differences in electrode consumption of various electric furnaces. It is also pointed out that when the influence of graphite electrode properties is small, the operating conditions of the furnace are the main factors for the change in electrode consumption.

Electric Arc Furnaces use electrical energy as the main energy source. Electric energy draws arcs through graphite electrode and charge discharge. Produce high temperatures up to 2000 ~ 6000 ℃. The scrap material is melted by means of arc radiation, temperature convection and heat conduction. In the configuration of graphite electrodes for steel-making electric arc furnaces, the basic principles of “ordinary power electric furnace with ordinary power graphite electrode, high power electric furnace with high power graphite electrode, and ultra high power electric furnace with ultra high power graphite electrode” should be followed .

Arc furnace electrodes, especially graphite electrode that connected by nipple joints, and can effectively prevent the electrodes from breaking during use. Electric arc furnaces are electric furnaces that use high temperatures produced by electrode arcs to smelt ores and metals. The energy is very concentrated when the gas discharge forms an arc, and the temperature in the arc zone is above 3000 ° C. For smelting metals, the electric arc furnace has greater process flexibility than other steel-making furnaces, can effectively remove impurities such as sulfur and phosphorus, the furnace temperature is easy to control, and the equipment occupies a small area.

Calculation Method of Graphite Electrode Consumption

The graphite electrode is the last part of the short-circuit power supply of the electric arc furnace. The end of the graphite electrode generates a strong arc to melt the charge and heat the molten steel, that is, the electrode is the central hub that converts electrical energy into thermal energy. The electrode is subjected to high temperature, furnace gas oxidation and colliding material impact during operation. In particular, the junction of the two electrodes has a higher resistance and lower conductivity than other places. Easy to trip, oxidize, fall off and break. As a result, the electrode is greatly consumed, and the smelting time is extended, and the productivity is reduced.

In 1982, Bowman divided the normal graphite electrode consumption into front end consumption and side consumption. Both can be calculated using the following formula:

Normal Graphite Electrode Consumption: CE = Cγ + Cs

Front-End Consumption: Cγ = Vγ · TOntap / W, Vγ = Kγ · I2 / dnγ

In the formula,

TOntap — electric furnace power transmission time, h;

W — Electric furnace tapping weight, t;

Vγ — consumption speed of electrode front end, kg / h;

Kγ-front-end consumption constant (Bowman gives Kγ = 0.0361 for AC arc furnace and n usually takes 0.58)

I ———— Arc current intensity, kA;

dγ ——— The diameter of the electrode front end, m.

Side Consumption: Cs = Vs · TTop-Top / W, Vs = 3Ks · S

In the formula,

TTop-Top — Electric furnace smelting period, h;

W — Electric furnace tapping weight, t;

Vs — consumption speed of electrode side, kg / h;

Ks — oxidation consumption rate, kg / (m2 · h);

S — oxidized surface area in the electrode furnace, m2.

At present, in the production process, the Bowman graphite electrode consumption model has been widely recognized. Wang Mingli and others believe that once the smelting process is stable, the current supplied by the power supply has the greatest impact on the electrode unit consumption.

It is generally believed that in the smelting process, the calculation of graphite electrode consumption has two concepts, net consumption and gross consumption. Net consumption refers to the technical consumption of electrodes consumed during high-temperature sublimation, oxidation and participation in smelting. Gross consumption is the sum of the net consumption and the losses that have not been participated in the smelting. In other words, the graphite electrode consumption model mentioned above is only technical consumption, that is, it is classified as net consumption. Gao Zhanbiao and others believe that at this stage the steel industry mainly uses the following two methods to calculate graphite electrode consumption.

(1) Production method

The output method is based on the amount of molten steel (finished product) produced in a certain period, and the amount of graphite electrode input during the same period minus the remaining amount on the furnace is consumed.

Gross Loss of Tons of Graphite Electrode: MM = MZ / MG

Net Consumption of Ton Steel Graphite Electrode: MJ = MC / MG

In the formula,

MZ—the total consumption of the electrode (input amount-remaining amount on the furnace), kg / t;

MC—The pure consumption of the electrode (input amount-remaining amount on the furnace-loss amount), kg / t;

MG-the amount of finished molten steel, t.

(2) Power consumption method.

The power consumption method is based on the cumulative power consumption of pure heating time in a certain period. The amount of graphite electrode input during the same period deducts the remaining amount on the furnace as the consumption (LF furnace is calculated based on the power consumption and electrode for each temperature increase of 1 ℃).

Graphite Electrode Consumption per Kilowatt Hour: MX = 1000 × MC / QH

In the formula,

MC-the pure consumption of the electrode (input amount-residual amount on the furnace-loss amount), kg / t;

QH ——— The cumulative power consumption in pure heating time, kW · h.

At this stage, when calculating the graphite electrode loss, steel companies generally include the amount that is lost without participating in the smelting. This can more fully reflect the center of gravity and key points of loss in the steelmaking process of the electric arc furnace. So as to find the shortcomings in the process parameters to solve.

Advantages of DC Electric Arc Furnace Electrodes

In the use of arc furnace electrodes, the advantages of using DC electric arc furnace electrodes compared to AC power supply are obvious in the heat transfer of the metallurgical process.

Disadvantages of AC Power Supply for Electric Arc Furnace

When the arc furnace is powered by an AC power supply, it has four main disadvantages: unstable arc; severe voltage flicker effect; very low electrode life; furnace wall loss is particularly serious. The reason for the unstable arc is that the arc is continuously extinguished and restarted at a frequency of 50 times per second. The lag of restarting the arc depends on the position of the electrode relative to the charge, the current setting value, and the furnace atmosphere and temperature.

Advantages of DC Electric Arc Furnace Electrodes

The DC arc is superior to the AC arc in terms of stability and unidirectionality, which has great benefits for heat transfer in the metallurgical process. Theoretical analysis points out that the use of direct current instead of alternating current is a major technical innovation measure. Since the DC current has no zero-crossing problem, the arc stability is improved, and the interference to the power grid is also reduced. In DC arc furnaces, the method of smelting metals using DC current is basically the same as AC arc furnaces. However, because the anode heat on the charge side is high, the “electricity-heat” conversion efficiency of the DC arc is high.

Schematic Diagram of DC Electric Arc Furnace Double Electrodes

In a two-electrode DC arc furnace, the arc burns between the two electrodes and the charge. The DC arc furnace uses a thyristor converter to convert AC to DC. The electric current is transferred into the furnace by means of a large current loop and double electrodes, so there is no need to provide furnace bottom electrodes.

Analysis of AC Arc Furnace Electrodes Loosening in Steel Making

Over the past decade or so, with the optimization of short processes and the development of refining processes, EAF steelmaking furnace has been greatly improved. Mainly manifested in large-scale and ultra-high power. The power supply mode is AC and DC. The difference between the two is that there are three graphite electrodes on the top of the AC arc furnace, which are connected to A, B and C three-phase alternating current. The DC arc furnace adds a set of rectifier equipment to change the input power from AC to DC. The graphite electrode on the furnace top was changed from three to one, and a bottom electrode was added on the furnace bottom. At present, about 80% of China’s steel-making enterprises still use AC arc furnaces.

AC Arc Furnace Electrodes Loosening

In AC arc furnace steelmaking, the current and voltage transmitted from the short wire are then transmitted to the electrode through the electrode holder. And an arc is generated between the electrode and the charge to melt the scrap. Only then can other steelmaking processes be completed. As shown below.

Main Circuit of Steel Making Electric Arc Furnace

Over the years, the loosening of the AC arc furnace electrodes has frequently occurred. The graphite electrodes or the nipples electrodes thread is damaged and cannot be reused, and the consumption is increased, which brings direct or indirect losses to the steel mill and the graphite electrode manufacturers. It even caused the steel mill to question and claim the quality of the graphite electrode from the manufacturing plant.

Effect of Three-phase Alternating Current on Graphite Electrode

To this end, graphite electrode manufacturers start qualitative analysis from the perspective of electric and magnetic fields by consulting relevant data. It was found that the direction of the phase sequence has a great influence on the loosening of the electrode.

Effect of Three-phase AC on Loosening of Graphite Electrode

A, B, and C three-phase AC arc furnaces will generate a rotating magnetic field and a rotating magnetic moment to the electrodes. When A, B, and C are in the clockwise phase sequence, the direction of the rotating magnetic distance is also clockwise, which is exactly in the same direction as the electrode thread loosening, which is easy to cause the electrode joint to loosen. Conversely, when A, B, and C are in the counterclockwise phase sequence, the purpose of tightening the electrode joint can be achieved.

Conclusion

Based on the above analysis, we have taken corresponding improvement measures for the loosening of electrodes in some steel mills. Adjusting the phase sequence in time has obtained obvious results. For example, the electric arc furnaces of a company’s steelmaking plant have loosened multi-phase electrodes after they were put into production. After adjusting the phase sequence counterclockwise, the arc furnace electrodes did not come off again.

If your AC arc furnace, during the smelting process, if the electrodes frequently loose and fall off. Please check the phase sequence first to ensure that the phase sequence is adjusted to the counterclockwise direction. Then determine whether the electrode is loose due to other reasons. This can reduce the cost of consumption and improve economic efficiency.

How to Choose Graphite Electrode for DC Electric Arc Furnace

DC electric arc furnace is a new type of electric furnace steelmaking equipment developed in the early 1980s. The initial DC electric arc furnace was transformed from the original AC electric arc furnace. How to Choose Graphite Electrode for DC Electric Arc Furnace? Some used 3 graphite electrodes and some used 2 graphite electrodes.

After the mid-1980s, most of the newly designed DC electric arc furnaces only used one graphite electrode. Compared with AC electric arc furnaces with three graphite electrodes of the same power, the total surface area of the electrode that was oxidized at a high temperature was greatly reduced. The DC arc furnace operating at the same high power can reduce the (hp) graphite electrode consumption per ton of steel by about 50%. DC arc furnace current does not produce skin effect and proximity effect when passing through the electrode. The current distribution is uniform on the electrode cross section, and the stability of the DC arc is good. The mechanical vibration is small during operation, and the noise of the electric furnace is also low.

The diameter of the graphite electrode used in the DC electric arc furnace is also calculated based on the capacity of the electric furnace and the allowable current density of the electrode. For ultra-high-power electric furnaces with the same input power, a DC furnace using one graphite electrode has a larger electrode diameter. For example, an AC arc furnace with a capacity of 150t uses an electrode with a diameter of 600mm, while a DC arc furnace with the same capacity uses an electrode with a diameter of 700 ~ 750mm. DC arc furnaces have higher quality requirements for graphite electrodes than graphite electrodes used in AC arc furnaces.

The Grade, Performance & Application of Graphite Electrodes

Based on the different standards of various graphite electrode manufacturers, the grades of graphite electrodes are generally as follows:

Regular graphite electrode (RP)
Impregnated graphite electrode
High Power Graphite Electrode (HP)
SHP Graphite Electrode (SHP)
Ultra High Power Graphite Electrode (UHP)

The graphite electrodes of Rongsheng graphite electrode manufacturer are equipped with tapered joints, which comply with national standards and international standards such as NEMA CG1, IEC 60239, JIS R7201 and so on.

The use and performance of graphite electrodes:

Used in steelmaking electric arc furnace, refining furnace, as conductive electrode;
Used in industrial silicon furnace, yellow phosphorus furnace, corundum furnace, etc., as conductive electrode.

Performance of Graphite Electrode:

Good conductivity
Strong thermal shock resistance
High mechanical strength

Applications of graphite electrodes

In actual use, the specifications and grades of graphite electrodes should be selected according to the specific furnace conditions. The first factor is the maximum current intensity. At the same time, the influence of other factors, such as the characteristics of the electric furnace, the type of charge, the smelting time, the amount of oxygen blowing, the mechanical requirements, and the steelmaking process system, must also be considered.

Generally, the physical and chemical indicators of most grade graphite electrodes have been standardized. However, in the process of use, the influence of temperature on some indicators must be considered sometimes.

Precautions when using graphite electrodes:

● According to the capacity of the electric furnace and the load of the transformer, select the grade and diameter of the electrode appropriately.
● When charging the electric furnace, a large piece of charge should be installed on the bottom of the furnace to prevent the charge from falling and hitting the electrode. During the smelting process, a large amount of non-conductive objects, such as lime, should be prevented from accumulating directly under the electrode, otherwise it will affect the electrode current, and even cause the electrode to break.
● Pay attention to the position of the furnace cover. If the furnace cover is misaligned, the furnace cover will be scratched when the electrode is raised and lowered, resulting in electrode damage.
● When connecting the electrodes, if there is any defect in the connector plugs, replace them and then connect them.
● After the electrode is connected, if there is a gap on the connection surface, be sure to find out the cause. Use after the gap is eliminated.
● The electrode must be used vertically.
● The electrode holder should be clamped between the upper and lower cords of the top electrode. It is strictly forbidden to sandwich the electrode in the cord (joint hole) and the middle electrode, otherwise the electrode column may be easily broken.
● Because the raw materials and production processes of different manufacturers may be different, the physical and chemical properties of the electrodes are also different. It is recommended that the connectors and electrodes produced by different manufacturers not be used in series.
