Abstract
An installation for producing hot-rolled strip from austenitic stainless steels; including a continuous casting machine and a rolling mill with a temperature adjustment system and a cooling system for cooling the rolling stock. The temperature adjustment system includes an installation having a furnace for preheating the cast slab to =1,150° C. and an installation for intensive heating including an inductive heating zone for adjustment of the run-in temperature of the cast slab into the finishing train of the rolling mill to above 1,150° C., for establishing a final rolling temperature to carry out the heat treatment by direct exploitation of the rolling heat. The cooling system includes a device for quenching the rolling stock to below 600° C. The temperature adjustment system includes only a first descaling system between the preheating installation and the intensive heating installation.
