Induction Furnace Refractory Lining with Silica Ramming ...

 · Because of dry preparation of the mass, the heating and sintering time needed is short. The specific cost of refractory per ton of steel made is low. Silica ramming mass can safely be used up to an operating temperature of 1600 deg C. Since it expands very little, it is superior to both alumina and magnesia refractories to resist thermal shocks.

Electric Arc Furnace (EAF)

The electric arc furnace (EAF) is the major producer of hot metal in the steel industry today. There are two types of EAFs: alternating current (AC) and direct current (DC). AC EAFs have three electrodes, while DC EAFs have two: a cathode, which is a single electrode in the roof of the furnace, and an anode in the bottom of the furnace.
