摘要： Method in which the pickling solution is sprayed onto the metal part in a confined atmosphere with an oxygen supply by feeding into the spraying enclosure an oxygen-containing gas, the pickling solution being recycled in a closed pickling solution circuit. The device for pickling metal surfaces comprises a spraying enclosure (1) with a collecting tank (2), means for spraying (6) a pickling solution (S) in said enclosure, means (11) for recirculating said solution between said tank (2) and said spraying means (6) and means (8,9) for passing an oxygen-containing gas through said enclosure, and optionally means (13) for maintaining the temperature of said solution, and control means. The method of the invention is designed to improve the productivity of lines for pickling stainless or alloy steel components while economising on reagents.

摘要： 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.
