Parmar Steel

The hot rolling process begins with either a thick or thin continuous cast slab exiting the reheat furnace at a rolling temperature hot enough to achieve the desired final properties. Due to the extreme amount of reduction done during this process, the slab must be heated above the material’s recrystallization temperature. After reheating, the material is descaled, which is where the iron oxide surface scale is removed with high-pressure water to ensure a clean surface.
