Title:
MANUFACTURE OF COLD-ROLLED STAINLESS STEEL STRIP
Document Type and Number:
Japanese Patent JP3241494
Kind Code:
B2
Abstract:
PURPOSE: To manufacture a cold-rolled steel strip having excellent surface gloss by manufacturing a cold-rolled base stock under specified conditions and cold-rolling the base stock by specifying the diameter of work roll of the final stand.
CONSTITUTION: The strip of austenitic stainless steel which is represented by SUS-304 is annealed after completing hot rolling. Successively, the steel strip is rapidly cooled at the cooling rate of ≥25°C/sec just after annealing or from the range of 850-400°C of the temp. of the steel strip after annealing. A cold- rolled base stock is manufactured by pickling after mechanically grinding the surface of the steel strip by 2μm with a grinder or the like. That base stock is cold-rolled by taking the diameter of work roll of at least the final stand of a cold tandem mill as ≤&phiv 400mm. In this way, intercrystalline cracking of the stainless steel strip is remarkably reduced.
