Characteristics of RP Graphite Electrode in Rongsheng

  • The RP graphite electrode also is known as the regular power graphite electrode.
  • Low ash, the ash content no more than 0.3%;
  • Low thermal expansion coefficient, less breakage, and low consumption;
  • High thermal shock resistance, low crushing and fracture rates;
  • competitive price;
  • Free consultation and installation.

Raw Material Characteristics of RP Graphite Electrode

The main raw material used in the production of the RP graphite electrode is petroleum coke. For ordinary power graphite electrode production, a small amount of pitch coke can be added. The sulfur content of petroleum coke and asphalt coke cannot exceed 0.5%.

The graphite electrode mainly uses petroleum coke and needle coke as raw materials, and coal pitch as a binder. It is made by calcination, batching, kneading, pressing, roasting, graphitization and machining. A graphite electrode is a conductor that releases electrical energy in the form of an arc in an electric arc furnace and heats and melts the charge. According to its quality index, it can be divided into the RP graphite electrode, HP graphite electrode, and the UHP graphite electrode.

Production Characteristics of RP Graphite Electrode

(1) Long production cycle. The production cycle of ordinary power graphite electrodes is about 45 days.

(2) Higher energy consumption. The production of 1t RP graphite electrode requires about 6000kW·h of electrical energy; thousands of cubic meters of gas or natural gas; about 1t of metallurgical coke particles and metallurgical coke powder.

(3) Many production processes. The production process includes calcination of raw materials, crushing of milling powder, ingredients, kneading, shaping, roasting, impregnation, graphitization, and mechanical processing. Its production requires many special types of mechanical equipment and special structure kiln. The construction investment is large and the investment recovery period is long.

(4) In the process of producing graphite electrodes, a certain amount of dust and harmful gases will be generated. We need to take perfect ventilation and dust reduction measures which are benefits to environmental protection, to eliminate harmful gases.

    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.

    The development of electric furnace steelmaking technology, the enlargement of electric furnaces, the increase of electric power per unit furnace capacity and the use of DC electric arc furnaces have constantly put forward new requirements for the variety and performance of graphite electrodes. The use of high-power and ultra-high-power electric furnace steelmaking can shorten the furnace melting time, improve production efficiency, reduce power consumption and reduce graphite electrode consumption.
