china graphite electrode for arc furnaces manufacturers
Introduction and application of china graphite electrode for arc furnaces manufacturers
china graphite electrode for arc furnaces manufacturers mainly use petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made through calcination, batching, kneading, pressing, roasting, graphitization, and machining. It is made in electric arc furnaces. The conductor that releases electric energy in the form of electric arc to heat and melt the furnace charge can be divided into ordinary power, high power and ultra-high power according to its quality index.
china graphite electrode for arc furnaces manufacturers include:
(1) Ordinary power china graphite electrode for arc furnaces manufacturers. It is allowed to use china graphite electrode for arc furnaces manufacturers with a current density lower than 17A/cm2, which is mainly used for ordinary power electric furnaces for steelmaking, silicon making, and yellow phosphorus making.
(2) Anti-oxidation coating china graphite electrode for arc furnaces manufacturers. China graphite electrode for arc furnaces manufacturers coated with an anti-oxidant protective layer (antioxidant of china graphite electrode for arc furnaces manufacturers). Form a protective layer that is both conductive and resistant to high temperature oxidation, reducing electrode consumption (19%-50%) during steelmaking, prolonging the service life of electrodes (22%-60%), and reducing electrode power consumption.
① The unit consumption of china graphite electrode for arc furnaces manufacturers is less, and the production cost is reduced to a certain extent. For example, a steelmaking plant uses about 35 china graphite electrode for arc furnaces manufacturers for the consumption of 165 china graphite electrode for arc furnaces manufacturers on the basis of the annual production stoppage of the first-level LF refining furnace and the consumption of 165 furnaces. The anti-oxidation technology of china graphite electrode for arc furnaces manufacturers is used. After that, 373 electrodes (153 tons) can be saved every year. When calculated at RMB 16,900 per ton of ultra-high power electrodes, it can save RMB 2.5857 million.
② China graphite electrode for arc furnaces manufacturers consume less electricity, save electricity consumption per unit of steelmaking, save production costs and save energy!
③As the number of replacements of china graphite electrode for arc furnaces manufacturers is less, the labor and risk factors of the operators are reduced, and the production efficiency is improved.
④ China graphite electrode for arc furnaces manufacturers are high-consumption and high-pollution products. It has very important social significance in the days when energy conservation, emission reduction and environmental protection are promoted. This technology is still in the research and development stage in China, and some domestic manufacturers have also begun to produce it. It has been widely used in developed countries such as Japan. At present, companies specializing in importing these anti-oxidation protective coatings have also appeared in China.
(3) High-power china graphite electrode for arc furnaces manufacturers. It is allowed to use china graphite electrode for arc furnaces manufacturers with a current density of 18-25A/cm2, which is mainly used for high-power electric arc furnaces for steelmaking.
(4) Ultra-high power china graphite electrode for arc furnaces manufacturers. It is allowed to use china graphite electrode for arc furnaces manufacturers with a current density greater than 25A/cm2. Mainly used for ultra-high power steelmaking electric arc furnace.
