Abstract

PURPOSE: To provide a nonmagnetic roll having high mechanical strength and stress corrosion cracking resistance and capable of applying strong electromagnetic stirring force to a slab by using a steel contg. C, Si, sol. Al, Mn, Cr, Ni, Cu, N, V, Nb, etc. restricted to specified concns.
CONSTITUTION: This nonmagnetic roll is formed a steel contg. ≤0.15% C, ≤1.0% Si, ≤0.050% sol. Al, 17.0W25.0% Mn, 6.0W11.5% Cr, ≤3.0% Ni, ≤3.0% Cu (Ni+ Cu≤3.0%) and 0.05W0.25% N. To the steel may be added 0.05W1.00% V and/or 0.05W1.00% Nb. This nonmagnetic roll has sufficient strength and toughness as a support roll, deteriorates hardly the toughness during use, and has very low permeability. Accordingly, a slab of superior internal quality is obtd. by means of the roll.
