600mm rp graphite electrode for arc furnace
The production of 600mm rp graphite electrode for arc furnace should be the first choice for high-quality needle coke
The raw material is the key technical element that determines the basic functional characteristics of the carbon material, and the performance of the raw material determines the performance of the manufactured carbon material. For the production of 600mm rp graphite electrode for arc furnace, high-quality needle coke is the first choice. However, only the quality of raw materials, lack of equipment, technology, management and technical know-how related elements, will not produce the same quality as 600mm rp graphite electrode for arc furnace.
Although the industrialized social production of needle coke in my country is later than that of foreign research companies, the economy has developed rapidly in recent years and has begun to take shape. In terms of total production resources, it can basically meet the production of 600mm rp graphite electrode by domestic carbon companies. The demand for the amount of needle coke for arc furnace. However, compared with foreign companies, there is still a gap in quality needle coke. Fluctuations affect the performance required for mass production of large-size and high-quality needle coke 600mm rp graphite electrode for arc furnace, especially the joint production of 600mm rp graphite electrode for arc furnace joints. Use high-quality needle coke.
Foreign carbon companies producing large-size 600mm rp graphite electrode for arc furnace often prefer high-quality petroleum needle coke as the main raw material coke. my country’s needle coke is currently mainly coal-based needle coke, and various carbon companies produce high-quality large-size UHP 600mm. rp graphite electrode for arc furnace often relies on imported petroleum-based needle coke.
At present, the needle coke produced by various enterprises is usually compared with the commercial performance indicators of foreign needle coke through ash content, true density, sulfur content, nitrogen content, particle size distribution, thermal expansion coefficient and other conventional performance indicators. Compared with foreign countries, there is still a lack of needle coke grading with different levels of performance.
When comparing the performance of needle coke, carbon companies should pay more attention to the classification of needle coke’s coefficient of thermal expansion (CTE), particle strength, degree of anisotropy, non-inhibited development status and The characteristics of the needle coke, such as the expansion and data, the temperature change interval during the expansion and contraction, can be characterized when the state is inhibited. Because the thermal properties of needle coke are very important to control the production of 600mm rp graphite electrode for arc furnace during the graphitization process, of course the influence of the thermal properties of the pitch coke formed after the binder and impregnant pitch is roasted is not ruled out.
