(1) Used for electric arc steelmaking furnaces. Electric furnace steelmaking is a major user of graphite electrodes. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace,

Utilize the high-temperature heat source generated by the arc between the electrode end and the furnace material for smelting.

(2) Used for submerged arc furnaces. The submerged arc furnace is mainly used for the production of industrial silicon and yellow phosphorus, and its characteristic is that the lower part of the conductive electrode is buried in the furnace material,

Arc is formed within the material layer and the heat energy emitted by the resistance of the furnace material is used to heat the furnace material. A submerged arc furnace with a high current density is required

Graphite electrodes are required.

(3) Used for resistance furnaces. The graphitization furnace for producing graphite products, the furnace for melting glass, and the electric furnace for producing silicon carbide all belong to resistance furnaces,

The materials loaded in the furnace are both heating resistors and heating objects. Usually, graphite electrodes used for conducting electricity are embedded in the furnace wall at the end of the resistance furnace, which is used for

The graphite electrode here is not continuously consumed.

(4) Used to prepare anisotropic graphite products. The blank of graphite electrodes is also used to process various heterogeneous graphite products such as crucibles, molds, vessels, and heating elements
