Hot rolling

Semi-finished products are re-heated to 1,200°C. This is above steel’s recrystallisation temperature, making it easier to form, but less suitable for precision applications like car bodies. Before it is rolled, scale is removed and the steel is cooled. During the flat steel hot rolling process, the steel thickness can be reduced from 22-1.25mm. The first stage of creating long products such as sections, tubes, wires and rods consists of rolling to create rods that range in width from 5-20mm.
