ResultHot rolling makes shaping and forming much easier, and it is even typically cheaper and quicker to manufacture. The objective is to breakdown the cast ingot into blooms or slabs for subsequent finishing into bars, plate or sheet. In hot-rolling steel, the slabs are heated initially at 1100°C-1300°C.
