China 92% Carbon Calcined Anthracite Coal Eca Carbon Raiser, Find details about China Carburizing Agent, Carburizing from 92% Carbon Calcined Anthracite Coal Eca Carbon Raiser
The main raw material for the synthetic graphite is fine calcined petroleum coke in powder form, add asphalt as binder, and then add a small amount of other accessories. After all kinds of raw materials are well matched, they are pressed into shape and then treated at 2500 ~ 3000ºC in a non-oxidizing atmosphere to make them graphitized. After high temperature treatment, ash, sulfur and gas content were greatly reduced.
Graphite recarburizers generally come from two ways, one is the waste cutting of graphite electrodes, and the other is the graphitized product of petroleum coke 3000 degrees.
