As steel is not ductile at room temperature, heavier reductions require it to be heated to temperatures of 1200-15000C to make it ductile by converting its crystal structure from BCC to FCC. In rolling mills, this operation is called reheating process and is carried out in reheating furnaces. Hot rolling
At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire drawing, extrusion, and machining.
