METHOD AND DEVICE FOR ANNEALING AND DESCALING STRIPS OF STAINLESS STEEL

摘要

The invention relates to a method for annealing and descaling hot-rolled strip of austenitic stainless steel. According to the invention, the steel strip is descaled in a coupled plasma descaling plant after annealing and subsequent cooling. The plasma descaling occurs under vacuum in several stages and the steel strip is subjected to a controlled cooling by cold rolling between said stages and after thee last stage, such that on exit from the plasma descaling plant the steel strip has a temperature below 100°C.
