Graphite Electrode Manufacturer China shares with you.
1. Used in the electric arc furnace
Electric furnace steelmaking is a large user of graphite electrodes. China's electric furnace steel output accounts for about 18% of crude steel output, and graphite electrodes for steelmaking account for 70% to 80% of the total graphite electrode usage. Electric furnace steelmaking uses a graphite electrode to introduce current into the furnace and uses a high-temperature heat source generated by an arc between the electrode end and the charge to perform smelting.
2. Used in mineral heat electric furnace
The mineral thermal electric furnace is mainly used for the production of industrial silicon and yellow phosphorus, which is characterized in that the lower part of the conductive electrode is buried in the charge, an arc is formed in the layer, and the heat is generated by the heat generated by the resistance of the charge itself, which requires regular power graphite electrodes need to be used for high-density mineral heat electric furnaces. For example, approximately 100 kg of graphite electrodes are consumed for each 1t of silicon produced, and approximately 40 kg of graphite electrodes are consumed for each 1t of yellow phosphorus.
3. Used in a resistance furnace
Graphite furnaces for the production of graphite products, melting furnaces for melting glass, and electric furnaces for the production of silicon carbide are all resistance furnaces. The materials contained in the furnace are both heating resistors and objects to be heated. Generally, graphite electrodes for electrical conduction are embedded in the resistance furnace end. In the hearth wall of the center, the graphite electrode used here is discontinuously consumed.
4. Used for preparing special graphite products
Graphite electrode blank is also used for processing into a variety of crucible, mold, vessel and heating bodies and other special graphite products. For example, in the quartz glass industry, 10t of graphite electrode billet is required for each 1t of the molten tube. It takes 100kg of graphite electrode blank to produce 1t quartz brick.
