The casting rolling plant is an efficient alternative to continuous casting and the hot-rolled mill process. The liquid steel is also cast and solidified but then cast into a thin slab and rolled into a hot strip in one round. The cooling and reheating step of the slab in the furnace is thus saved in the casting rolling plant.
