PURPOSE:To remove flaws and to manufacture cold rolled hoop steel of stainless steel having beautiful surface by grinder grinding a hoop steel of stainless steel changing grinding direction by more than a specified angle every time when grain size of the grain is changed before finishing cold rolling. CONSTITUTION:When removing surface flaws of a hot rolled hoop steel of stainless steel or cold dolled hoop steel by grinder grinding before finishing cold rolling, the direction of grinding is changed by >=30 deg., preferably about >=45 deg., every time when grain size of the grain of the grinder is changed. Thus, surface flaws are removed effectively by small number of processes, and a lustrous, beautiful cold rolled hoop steel of stainless steel is obtained. |
