STAINLESS STEEL FOR WIRE ROD HORIZONTAL CONTINUOUS CASTING EXCELLENT IN LONG TIME CASTABILITY

摘要

PURPOSE: To produce a stainless steel for wire rod horizontal continuous casting excellent in longtime castability by specifying the componental compsn. constitut ed of Ni, Cr, C, Si, Mn and iron and the contents of chalcogens such as S, Se and O. ;CONSTITUTION: A stainless steel for wire rod horizondal continuous casting contg., by weight, ≤40% Ni, 13 to 28% Cr. ≤0.2% C, ≤4% Si and ≤10% Mn, and the balance iron is incorporated with 0.004 to 0.020% of one or more kinds of chalcogens among 0.004 to 0.020% S, 0.004 to 0.020% Se and 0.004 to 0.010% O. In this way, the surface tension of this stainless steel is reduced to increase its fluidity. Thus, in a wire rod horizondal continuous casting method for a diameter of about ≤12mm of the stainless steel, the rupture of the wire rod in the process is prevented to prevent deterioration in its productivity and yield, thus stable continuous casting is made possible for a long time.;COPYRIGHT: (C)1995,JPO
