Yiheng New Materials Co., Ltd.

Graphite electrode, mainly from the domestic petroleum coke and imported needle coke, is widely used in electric arc furnace,ladle furnace, submerged arc electric furnace for theproduction of alloy steel, metal and nonmetallic materials. 


Our graphite electrodes include regular power, high power, super high power and ultra high power. They are characterized by low resistivity, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, ect.  Our plant offers various dimensions and grades to meet customers' requirements for the specific applications.


Usage : 
Graphite  Electrodes  has good electrical properties and chemical resistance, which has high mechanical strength at high temperature and good seismic performance.It is good conductor of heat and electricity, widely used in electric arc furnace steelmaking, refining furnace, ferroalloy production, industrial silicon, phosphorus corundum and other submerged arc furnace with an electric arc furnace smelting and other high temperature furnace.


Features :
high physical volume density
super anti-press power
low rate of electric resistance
strong anti-oxidizes
