Generally speaking, graphite electrode refers to petroleum coke and asphalt coke as aggregate, coal asphalt as binder, which is made by calcination of raw materials, crushing and milling, compounding, kneading, forming, roasting, impregnation, graphitization and mechanical processing. A high temperature resistant graphite conductive material called an artificial graphite electrode (abbreviated as a graphite electrode). The difference from the natural graphite electrode lies in the raw material, and the raw material of the natural graphite motor is natural graphite. Therefore, the price of the graphite electrode refers to the price of the artificial graphite electrode.
The price of the graphite electrode depends on the raw materials used in the preparation, the cost of the preparation process, and the transportation cost.
From the point of view of raw materials, the raw materials selected for different grades of graphite electrodes are different. The raw material used for high-power graphite electrodes is needle coke, and the cost of needle coke is higher than that of petroleum coke.
Looking at the preparation process of the graphite electrode, the raw material of the graphite electrode needs to be subjected to a series of processes such as calcination, crushing, milling, compounding, kneading, molding, roasting, impregnation, graphitization and mechanical processing. Graphite conductive material. The whole process of production is prepared, the process is cumbersome, and some processes need to be repeated 2-3 times. The time spent on each process cannot be ignored. The cost of time is also counted in at this time.
In addition, the graphite electrode needs to be machined at the end. With the continuous improvement of graphite electrode quality and technical requirements in the steelmaking industry, graphite electrodes are developing in the direction of large size, high precision and high power. This requires more precise machining of the graphite electrode. Therefore, the machining of the graphite electrode, including the keyhole, the scraping end face, the outer circle of the car, the milling thread and the like are more rigorous.
Finally, the packaging and transportation of the graphite electrode, the graphite electrode is most taboo and moist, therefore, the packaging of the graphite electrode needs to be better waterproof. Since the graphite itself is easily broken, it is necessary to pay close attention to the integrity of the graphite electrode during transportation, and to avoid the external force and break. The loss during transportation is also counted in the cost of the graphite electrode.
