Q:What are graphite electrodes?
A:Graphite electrode is an important conductive material in electrode electrosmelting industry. It has good electrical and thermal conductivity, high mechanical strength, high temperature resistance and good corrosion resistance. It is widely used in electric arc steelmaking and ore electric furnace (production of ferroalloy, pure Silicon, yellow phosphorus, matte, calcium carbide, etc., and resistance furnaces (such as graphitization furnaces for producing graphite electrodes, melting furnaces for melting glass, electric furnaces for producing silicon carbide, etc.) have become an important part of the contemporary raw material industry.
Properties: graphite electrode low resistivity, graphite electrode good conductivity,graphite electrode low ash, graphite electrode uniform and graphite electrode compact structure,graphite electrode good oxidation resistance, graphite electrode high mechanical strength.
A:The delivery time is about 15-30days after receipt of payment.
A:Before inquiry us the price, pls be kindly send us the detail data of the material you need.
I will give you our best price.
A:You can get the best quality which you need with the equal price.
