Which fields can graphite electrodes for electrolysis be used in?

1. Used in electric arc steelmaking furnace

Mainly used for electric furnace steelmaking. Electric furnace steelmaking uses graphite electrodes for electrolysis to introduce electric current into the furnace. A strong electric current generates arc discharge through gas at the lower end of the electrode, and uses the heat generated by the arc to smelt. According to the capacity of the electric furnace, graphite electrodes for electrolysiss of different diameters are equipped. In order to make the electrodes continue to be used, the electrodes are connected by the electrode screw joints. The graphite electrodes for electrolysis for steelmaking accounts for about 70-80% of the total amount of graphite electrodes for electrolysis.

2. Used in mine thermal electric furnace

The submerged electric furnace is mainly used to produce ferroalloys, pure silicon, yellow phosphorus, matte and calcium carbide, etc. Its characteristic is that the lower part of the conductive electrode is buried in the charge, so in addition to the heat generated by the arc between the electric plate and the charge, the current passes through the charge At this time, heat is also generated by the electrical resistance of the charge. Each ton of silicon needs to consume about 150kg of graphite electrodes for electrolysis, and each ton of yellow phosphorus needs to consume about 40kg of graphite electrodes for electrolysis.

3. For resistance furnace

Graphitization 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 in the furnace are both heating resistors and heated objects. Usually, the graphite electrodes for electrolysis for conduction is inserted into the furnace head wall at the end of the hearth, so the conduction electrode is not consumed continuously.

In addition, a large number of stone avoiding electrode blanks are also used to process various crucibles, graphite boats, hot die casting molds and vacuum electric furnace heating elements and other special-shaped products. For example, in the quartz glass industry, 10t graphite electrodes for electrolysis blanks are needed to produce lt electric fusion tubes, and 100kg electrode blanks are consumed for every lt quartz brick produced.

The main products of CGM are graphite electrodes for electrolysis, graphite crucible, graphite joint, graphite special-shaped parts, graphite rod, graphite plate, graphite powder and other graphite products.
