Title: Production of high delta-fe austenitic stainless steel strip
Inventor: SUEHIRO TOSHIYUKI
IPC: B23K35/02
Filed: 1990-11-30
Abstract: PURPOSE:To press solidification shrinkage cavities and to eliminate cracking at the time of reducing by performing continuous rolling at respectively specified temp. and reduction of area. CONSTITUTION:Rolled-in scales are liable to occur when rolling temp. is lower than 1100 deg.C, and, when it exceeds 1250 deg.C, damage to rolls is increased. Further, after casting, continuous rolling is done at the above prescribed temp. at 5-30% reduction of area. The pressing of solidification shrinkage cavities becomes insufficient when reduction of area is below 5%, and, when it exceeds 30%, pressing effect becomes saturated and wear on hot rolls is increased and, as a result, surface flaws are liable to occur. The solidification shrinkage cavities can be pressed by means of rolling after continuous casting under the above conditions. Subsequently, the stages of annealing, pickling, cold rolling, etc., are exerted, if necessary, by which a stainless steel strip for flux cored wire, etc., can be produced.
