METHOD FOR MANUFACTURING AUSTENITIC STAINLESS STEEL PLATE WITH GOOD INTERNAL QUALITY BY TWIN-ROLL STRIP CASTING PROCESS

摘要

The present invention relates to a primary quality convenience produced in the strip casting process, and more particularly, to an invention relating to a method or a quality that wishes to improve the state quality comfort by controlling the columnar generate development within the cast slab increased the cast steel.; The invention in opposite directions a pair of rolls and each side surface supplying an inert nitrogen gas into the immersion nozzle and the Kang Full for the top surface of supplying molten steel into the edge dam and the Kang Full for being installed so as to form a Kang Full for the rotating equipped with a meniscus shield in pairs roll strip casting process for casting a thin plate that, by controlling the molten steel flow in the width direction of the discharge port of the immersion nozzle to prevent the non-coagulation phenomena, such as bulging or hot band at cast end provides a method for producing the internal quality is excellent austenitic stainless steel by strip casting process of the feature.
