product description
Graphite electrodes mainly use petroleum coke and needle coke as raw materials, coal tar pitch as binder, and are calcined,It is made by batching, kneading, forming, roasting, graphitization, and machining. It is released into the electric arc furnace as an arc conductor to heat and melt the charge. It has low resistivity, good conductivity, low ash content, uniform and compact structure, and good oxidation resistance. High mechanical strength, etc.
Features:
low resistivity
good electrical conductivity
low gray
good antioxidant
High mechanical strength
