Thin Slab Casting is a significant evolutionary step in casting methodology and allows greater efficiency and therefore cost-effectiveness to be applied to the casting process. Thin slab casting is a high-speed caster that continuously cast slab of thickness 60 to 75 mm. This thin slab is heated in a state-of-the-art tunnel furnace and is directly fed into the hot rolling mill. It is an energy-efficient process where no reheating furnace and roughing mills are required.
