Processing

RP Graphite Electrode production processing are as below:

Mill mix→Baking→Pitch Impregnation→Graphitizing→Machining→Finished Electrodes with Nipples

 

Application

1. RP Graphite Electrode is widely used in ladle furnace and smelting furnace to smelting.
2. It also can be used in producing the industrial silicon, phosphor, quartz glass, corundum, rare earth and other 
industrial production.
