Graphite electrode is a high-temperature resistant graphite conductive material, and do you know the purpose of graphite electrode? Let me introduce it below.

Graphite electrode classification: regular power graphite electrode (RP); high power graphite electrode (HP); ultra-high power graphite electrode (UHP).

(1) Used in Electric Arc Furnace

In the electric furnace steelmaking method, a large number of graphite electrodes are usually used. Electric furnace steelmaking uses graphite electrodes to introduce working current into the furnace. The strong current can generate arc discharge through these gases at the lower end of the electrodes, and use the heat generated by the arc for smelting. According to the capacity of the electric furnace, it is equipped with graphite electrodes of different diameters. To continuously use graphite electrodes, the electrodes are connected by electrode-threaded joints. Graphite electrodes for steelmaking account for about 70-80% of the total graphite electrode consumption in my country.

(2) Used in submerged Heat Electric Furnace

Submerged thermal electric furnaces are mainly used to produce ferroalloy, silicon, yellow phosphorus, calcium carbide, matte, etc. It is characterized by the fact 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 Heat is also generated by the resistance of the charge when passing through the charge. Each ton of yellow phosphorus needs to consume about 50kg of graphite electrodes, and each ton of silicon needs to consume about 160kg of graphite electrodes.

(3) For Resistance Furnace

Resistance furnaces include graphitization furnaces for the production of graphite products, furnaces for melting glass, and electric furnaces for the production of silicon carbide, etc. The materials in the furnace are both a heating resistor and a heated object.

(4) For processing

Many graphite electrode blanks are also used to process various crucibles, graphite boats, hot pressing molds, vacuum electric furnace heating elements, and other special-shaped products.

In addition, graphite materials at high temperatures include graphite electrodes, graphite molds, and graphite crucibles. These three types of graphite are prone to oxidative combustion reactions at high temperatures, resulting in more pores on the surface of the material, resulting in loose structures, and affecting the service life.
