CONTINUOUS CASTING METHOD FOR REDUCING THE WIDTH DEVIATION OF A FERRITIC STAINLESS STEEL FIRST SLAB WITH IMPROVED SLAB EDGE FAULTS OF A HOT ROLLED COIL

摘要

PURPOSE: A continuous casting method for reducing the width deviation of a ferritic stainless steel first slab is provided to reduce the slab edge faults of a hot rolled coil by reducing the width deviation of a first slab during a continuous casting process.;CONSTITUTION: A continuous casting method for reducing the width deviation of a ferritic stainless steel first slab is as follows. Molten steel flows into a mold through a ladle-tundish. The molten steel flowing into the mold is first cooled. The molten steel is second cooled. The rising acceleration of a first slab is controlled less than 0.06m/min∧2. The maximum width deviation of the first slab is less than 10mm.;COPYRIGHT KIPO 2010
