METHOD AND DEVICE FOR DESCALING A METAL STRIP

摘要

The invention relates to a method and a device for descaling a metal strip (1), especially a hot-rolled strip consisting of normal steel or a cold-rolled or hot-rolled strip consisting of austenitic or ferritic stainless steel. According to said method, the metal strip (1) is guided in a transport direction (R) through at least one plasma descaling device (2, 3) in which it is subjected to a plasma descaling process. The aim of the invention is to improve the production of one such metal strip. To this end, the metal strip (1) is subjected to a regulated cooling process in a cooling device (4, 5) following the plasma descaling process in the at least one plasma descaling device (2, 3), in such a way that it has a defined temperature downstream of the cooling device (4, 5). The invention also relates to a method, according to which the strip is provided with a coating consisting of a coating metal, using the heat produced by the plasma descaling process, following the same.
