Grate electrode

Grate electrode is made of petroleum coke, needle coke and coal pitch, through calciningã€batchingã€kneadingã€formingã€bakingã€gratizing and machining. It is a conductor that releases electric energy in an arc furnace to heat the furnace. Mainly used in electric oven like smelting steel, smelting silicon and smelting yellow srus.

Classification

RP: (Regular Power grate electrode), HP: (High Power grate electrode), UHP: (Ultra High Power grate electrode), IP: (Impregnated grate electrode), SHP: (Standard-High Power grate electrode), And Nipples.
