Abstract
PURPOSE: To manufacture the titled steel free from surface cracks and causing no flow on a product surface even after hot rolling by forming a steel having a specified composition contg. C, Si, Mn, P, S, Al, N, Ti and B into a slab by continuous casting.
CONSTITUTION: A steel having a composition consisting of 0.03W0.30% C, 0.05W 0.60% si, ≤2.0% Mn, ≤0.03% P, ≤0.02% S, ≤0.08% Al, ≤0.08% N, 0.005W 0.03% Ti, 0.0003W0.003% B and the balance Fe with impurities and satisfying the relation of equationIis formed into a slab by a continuous casting method. The steel may further contain ≥1 kinds of element selected from groupIconsisting of ≤0.40% Mo, ≤1.0% Ni, ≤0.60% Cr, ≤0.50% Cu and ≤1.0% W and/or group II consisting of 0.0005W0.03% REM, 0.0005W0.03% Ca and ≤0.10% Zr. By adding such a specified amount of Ti to a B-added steel obtd. by a continuous casting method, surface cracking is prevented thoroughly.
