Electric furnace steel making is a major use of graphite electrodes. At present, the output of electric furnace steel accounts for about 18% of the output of crude steel, and the graphite electrode used in steelmaking accounts for 70% ~ 80% of the total consumption of graphite electrode. The graphite electrode is used to introduce the current into the furnace, and the high temperature heat source generated by the electric arc between the electrode end and the charge is used for smelting.
2. Used in mine electric furnace
The ore thermoelectric furnace is mainly used for the production of industrial silicon and yellow phosphorus, etc. Its characteristic is that the lower part of the conductive electrode is buried in the charge, and an arc is formed in the charge layer, and the heat energy generated by the resistance of the charge itself is used to heat the charge. For example, about 100kg of graphite electrode is needed for each 1t of silicon production, and about 40kg of graphite electrode is needed for each 1t of yellow phosphorus production.
3. Used in resistance furnace
The graphitization furnace for producing graphite products, the melting furnace for melting glass and the electric furnace for producing silicon carbide all belong to the resistance furnace. The materials in the furnace are both the heating resistance and the object to be heated. Generally, the graphite electrode for conducting is embedded in the furnace wall at the end of the resistance furnace, and the graphite electrode used here is used for discontinuous consumption. Graphite electrode price reasonable, welcome to consult.
4. Used for preparing special graphite products
Graphite electrode blank is also used for processing into a variety of crucible, mold, vessel and heating body and other special graphite products. For example, in the quartz glass industry, 10t of graphite electrode billet is required for each 1t of molten tube. It takes 100kg of graphite electrode blank to produce 1t quartz brick.
