graphite electrode

Graphite electrode is a major conduction material used in the electric smelting industry.whichhas the properties of superior electric conductivity, thermal conductivity, high strength, oxidation and corrosion resistance in high temperature. Graphite electrode is typically used in the electric arc furnace smelting steel, the submerged-arc furnace producing ferroally, pure silicon, phosphor,matte,calcium carbide, etc., and the electric resistance furnace, such as graphitization furnaces producing graphite electrode, glassmelting furnaces, electric furnaces producing carbofrax, etc. Now days, graphite electrode has been essential part of the raw material industry.There are four types of graphite electrodes:Carbon,RP,HP, and UHP Ash contentpole/nipple%0.30.30.50.5UHP HP item----unit200-400450-500550-700Electrical resistancepole/nippleμΩm7.0/6.07.0/6.07.0/5.8Bending strengthpole/nippleMpa10.5/16.010.0/16.010.0/16.0Young's moduluspole/nippleGpa12.0/16.012.0/16.012.0/16.0Bulk densitypole/nippleg/cm31.63/1.731.62/1.721.62/1.72100°c-600°c CTEpole/nippleX10-6/°c2.4/2.22.4/2.22.4/2.2Ash contentpole/nipple%0.30.30.3 RP item----unit75-200250-350400-500Electrical resistancepole/nippleμΩm8.0/7.58.0/7.58.0/7.5Bending strengthpole/nippleMpa10.0/15.09.0/15.08.0/15.0Young's moduluspole/nippleGpa12.0/14.012.0/14.012.5/14.0Bulk densitypole/nippleg/cm31.58/1.681.58/1.681.58/1.68100°c-600°c CTEpole/nippleX10-6/°c2.7/2.52.7/2.52.7/2.5Ash contentpole/nipple%0.30.30.3
