Bottom Ring for Electric Arc Furnace

Bottom ring is applied for melting of industrial silicon and Ferrosilicon furnace， it’s mainly for protection for pressure ring on the top surface, that the operation environment is very bad. Traditional bottom ring is made of casting, which features relative high impurity for material, loss degree for casting structure, has casting defect, coarse grain, low density, poor mechanical property and poor cooling performance. The forged copper plate drilled structure bottom ring features good performance, long work life etc. advantages.
