In recent years, with the introduction of precision molds and high-efficiency molds (mold cycle is shorter and shorter), people's requirements for mold making are getting higher and higher, due to the copper electrode's own various conditions, has become increasingly unable to meet the mold industry Claim. Graphite electrode as EDM electrode material, with its high machinability, light weight, forming fast, minimal expansion rate, loss is small, easy to repair, etc., in the mold industry has been widely used, instead of copper electrode has become inevitable.

(1) electric furnace steelmaking. Electric furnace steel is the use of graphite electrode to the furnace into the current, a strong current in the bottom of the electrode through the gas arc discharge, the use of arc heat generated for smelting. According to the size of the furnace capacity, with different diameter of the graphite electrode, in order to make the electrode continuous use, the electrode between the electrode through the threaded connection. Graphite electrodes for steelmaking are about 70 to 80% of the total amount of graphite electrodes.

(2) for the mineral heating furnace. Graphite Electrode Electric furnace is mainly used for the production of ferroalloy, pure silicon, yellow phosphorus, copper and calcium carbide, which is characterized by the lower part of the conductive electrode buried in the charge, so in addition to electricity between the board and the charge heat generated, the current Through the charge when the charge from the charge also produce heat. Calcium per ton of graphite consumption of about 150kg per ton of yellow phosphorus need to consume graphite electrode about 40kg.

(3) for resistance furnace. The graphite furnace for the production of graphite products, the melting furnace for melting glass, and the electric furnace for producing silicon carbide are all resistance furnaces. The material contained in the furnace is both the heating resistor and the object to be heated. In general, the conductive graphite electrode is inserted into the furnace wall of the hearth of the hearth, so that the conductive electrode is not continuously consumed.

Baofeng County Jinshi New Material Co., Ltd. is one of the major manufacturers of domestic graphite mold and carbon mold. It mainly produces all kinds of graphite products; graphite thermal field components; graphite accessories; vacuum furnace, graphite furnace for induction furnace, etc., won the praise of customers The
