Abstract

PURPOSE: To manufacture a nonmagnetic roll having enough strength, ductility and toughness by subjecting a steel contg. a specified percentage each of C, Si sol. Al, Mn, Cr, N, etc. to hot working and heat treatment under specified conditions.
CONSTITUTION: A steel consisting of 0.30W0.50% C, ≤1.00% Si, ≤0.05% sol. Al, 17.0W25.0% Mn, ≤3.0% Cr, 0.05W0.20% N, one or ≥2 kinds among 0.05W2.00% Mo, 0.05W1.00% V, 0.05W1.00% Nb, ≤3.0% Cu and ≤3.0% Ni (Cu+Ni≤3.0%), and the balance Fe with inevitable impurities is hot worked at ≥50% reduction of area and heat treated by keeping at 550W1,000°C for 30minW15hr. Thus, a nonmagnetic roll having strength enough to support a slab, high SCC resistance and toughness and capable of applying strong electromagnetic stirring force to the slab is manufactured.
