COMPOSITION AND USE OF GRAPHITE ELECTRODE

Hello,sirs ,we are from China's graphite electrode supplier, HEBEI YUNSHUI NEW ENERGY TECHNOLOGY CO.LTD,we mainly produce a variety of graphite products,especially our most famous electrode products,

Graphite electrode refers to petroleum coke and needle coke as aggregate ,asphalt is used as a binder, after raw material calcined,broken, grinding,mixing,kneading,,molding,calcination,impregnation,

graphitization and mechanical processing and made of a kind of high temperature resistance of graphite conductive material,

called artificial graphite electrode(hereinafter referred to as graphite electrode),to distingguish it from the natural graphite as the raw material of natural graphite electrode preparation.

1、Used for electric arc furnace

Electric steelmaking is a major use of graphite electrodes.graphite electrode used in steelmaking accounts for 70%-80% of the total graphite electrode consumption,steelmaking in electric furnace is carried out by using graphite electrode to introduce current into the furnace and the hot heat source generated by electric arc between the electric extreme part and the charge.

2、For the thermal electric furnace

thermal electric furnace is mainly used in the production of industrial yellow phosphorus and silicon,etc,its characteristic

is the lower part of the conductive electrode burried in furnace charge ,arc formed within the material layer,and us the furnace charage itself from the resitance of the heat energy to heating furnace charge,one of the high current density required-arc furnace with graphite electrode,such as silicon 1 t per production to consumption of graphite electrode is about 100kg,per 1 t yellow phosphorus production to consumption of graphite electrode,about 40kg.

3、For resistance furnace

the graphitization furnace for producing graphite products,the melting furnace for melting glass and the electric furnace for producting silicon,carbide belong to the resistance furnace ,the materials loaded in the furnace are both the thermal resistance and the heated object,generally ,the graphite electrode used for conducting electricity is embedded in the furnace wall at the resistance furnace end,and the graphite electrode used here is discontinuous consumption.

4、Used for preparation of heteromorphic graphite products.

The blank of graphite electrode is also used for processing various shaped graphite products such as crucible ,mould,boat dish and heating element,For example,in the quartzglass industry,10 t of graphite electrode blank is required for every 1 t of electric fuse ,for every 1 t of quartz brick,100kg of graphite electrode blank is consumed
