MANUFACTURING FERRITE STAINLESS STEEL WITH IMPROVED FORMABILITY AND RIDGING PROPERTY BY CONTROLLING TEXTURE IN A COLD ROLL PROCESS

摘要

PURPOSE: A manufacturing ferrite stainless steel with improved formability and ridging property is provided to omit a grinding process by reducing the height of ridging which has a surface stripe pattern which is generated during a forming process.;CONSTITUTION: A manufacturing ferrite stainless steel with improved formability and ridging property comprises following steps. Stainless steel is hot-rolled by controlling vertical cold strip velocity ratio, and vertical cold strip roll size ratio, and maximum pressure ratio according to finishing strip pass. A hot rolling plate is annealed. A cold strip and a cold rolling plate are annealed.;COPYRIGHT KIPO 2010
