Smelting Of Aluminium Process Through Submerged Arc Furance

Metal Smelting Furnace | Shanghai JEVEN Technology Service .

Submerged ARC Furnace (SAF) Submerged ARC Furnace (SAF) is used for melting alloy and other nonconductive material, because the electric ARC will be happened below raw material, it means electric ARC is submerged under the material, so it is called Submerged ARC Furnace (SAF). In fact, it just be normal Electric ARC furnace (EAF).
