CASTING ROLL OF A TWIN ROLL STRIP CASTER FOR CASTING MARTENSITIC STAINLESS STEEL STRIP AND A METHOD FOR CASTING MARTENSITIC STAINLESS STEEL STRIP BY A TWIN ROLL STRIP CASTER INCLUDING THE CASTING ROLL

摘要

PURPOSE: A casting roll of a twin roll strip caster for casting martensitic stainless steel strip and a method for casting martensitic stainless steel strip by a twin roll strip caster including the casting roll are provided to solidify molten steel uniformly in a lateral direction by optimally controlling casting variables, including the crown value of casting rolls, the temperature of molten steel, and the amount of cooling water.;CONSTITUTION: A casting roll(3) of a twin roll strip caster for casting martensitic stainless steel strip is formed with a crown where C50/E50 is 1.2-1.5. As to C50/E50, E50 is a crown value from an edge to 50mm of the casting roll in the lateral direction and C50 is a crown value from the center to the 50mm point. Molten steel(4) for casting comprises C of 0.1-1.5weight%, Cr of 12-15weight%, Ni of 1weight% or less, and Fe and inevitable impurities of the remaining amount.;COPYRIGHT KIPO 2012
