Reheating Furnaces serve the purpose of heating steel blooms, billets or slabs in steel rolling mills. Reheating furnaces takes this steel stock up to approximately 1200 degree Celsius. The steel begins to deform at this temperat ure, and the steel rolling process can begin. In a reheating furnace, the heat provided to the steel stock is constant.
