Manufacture method of austenitic stainless steel plate with good quality by twin-roll strip casting

摘要

The present invention is rolled thin pair of austenitic stainless steel is manufactured from casting to casting thin STS304 if the river as been made in order to solve the hot band phenomenon and the residual delta ferrite and such edge build-up phenomenon that occurs in the developing unsolidified slab opposite ends , each end roll dendrite generation in the unsolidified portion of the molten steel flow pattern is advantageous to stably grow by supplying a molten steel so as to have the edge relates to a hot band caused by a drastic reduction in the fraction of dendrite end that is , the molten steel supply nozzle capable of preventing coagulation phenomena , such as bulging US .
