METHOD AND PRODUCTION LINE FOR MAKING OF COLD ROLLED FLAT ARTICLE FROM STAINLESS STEEL Russian patent published in 2015 - IPC C21D8/02 B21B3/02 

FIELD: process engineering.

SUBSTANCE: invention relates to production of cold-rolled flat article (E) from hot-rolled scaled strip (W) of stainless steel. In compliance with this process, scaled hot-rolled strip (W) is cold rolled to steel flat article (E). Cold-rolled flat steel article (E) is annealed to remove the scale therefrom. After cold-rolling of hot-rolled strip (W), cold-rolled steel flat article (E) as-cold worked is subjected, prior to annealing, to scale removal process. Here, scale is mechanically removed from said flat article (E). Production line comprises one cold-rolling stand (5-7), at least one annealing furnace (11) and at least one device (9, 10, 12) for mechanical removal of scale from cold-rolled flat article. At least one of said devices (9, 10) is arranged ahead of the inlet of annealing furnace (11) in direction (F) of cold-rolled steel flat article (E) transfer.

EFFECT: improved mechanical properties of finished product.
