Abstract
PURPOSE:To improve quality of a product by cooling at the specific cooling speed at the time of cooling the steel composing of the specific contents of C, Si, Mn, Ti, N and Fe. CONSTITUTION:At the time of cooling the steel containing of by weight 0.03-0.25% C, 0.01-0.5% Si, 0.3-1.8% Mn, 0.004-0.04% Ti, 0.002-0.008% N and the balance Fe, it is cooled from 800 deg.C to <=600 deg.C at >=2 deg.C/sec and <=50 deg.C/sec cooling speed. In the above steel composition, further <=0.05% Al, <=1.5% Cu, <=5% Ni, <=1% Cr, <=1% Mo, <=0.2% Nb, <=0.5% V and <=0.0025% B may be contained. By this method, as fine grains of ferrite is generated in the coarse austenitic grain, the quality of the thick steel plate in casting as it is improved.
