发明名称 Method and Production Line for Producing a Cold-Rolled Steel Flat Product from a Non-Corroding Steel
摘要 A method and a production line for producing a cold-rolled steel flat product from a hot strip with scale adhering to it and consisting of a non-corroding steel. The hot strip with scale adhering to it is cold-rolled into a steel flat product, the cold-rolled steel flat product is annealed and the annealed steel flat product is descaled. According to the invention, the cold-rolled steel flat product obtained after cold rolling the hot strip is subjected to descaling treatment in the hard-rolled state before annealing, in which the scale present on the cold-rolled steel flat product is mechanically removed. In this way, methods and production lines can be implemented, by means of which cold-rolled steel flat products can be produced cost-effectively from non-corroding steel with an improved surface finish.
