PURPOSE:To obtain a stainless steel strip having excellent surface luster by executing pre-rolling at the specific draft holding the specific thickness of liquid lubricant on roll surface, specifying the size of work roll diameter in the finish stand and executing cold-rolling. CONSTITUTION:After executing annealing and pickling to the hot-rolled stainless steel strip, pre-treatment rolling is executed at >5% draft under condition of applying <=1mum thickness of the liquid lubricant on the roll surface and after that, the cold-rolling is executed with cold tandem mill, in which the work roll diameter of at least the finish stand is made <=400mmphi, to manufacture the cold-rolled stainless steel strip. Further, this is rolled with small diameter roll having <=150mmphi work roll diameter. This stainless steel strip has excellent surface luster equal to or more than the surface luster obtd. by rolling with only Sendzimir mill. |
