Process for the continuous production of a rolled stainless steel sheet strip and continuous production line for carrying out the process

Abstract

Process for continuously producing on a production line a rolled stainless steel sheet product having an improved surface state, characterized in that the hot produced sheet is subjected to a treatment comprising at least: a primary pickling for removing scale, cold rolling in at the most three rolling passes, a final annealing, a final pickling, and a cold rolling of the "skin pass" type. There is optionally effected, before the primary pickling, a stretcher levelling which produces a residual elongation of 1 to 5% for cracking the layer of oxide and rendering the sheet planar. Apparatus for carrying out the invention process is also described.
