PURPOSE:To manufacture a hot rolled steel sheet for enamel having superior fish scale resistance and causing hardly softening after calcination by hot rolling a steel material contg. specified amounts of C, Ti and B and by carrying out coiling at a specified temp. CONSTITUTION:The composition of a steel material is composed of, by weight, 0.015-0.04% C, 0.1-0.25% Ti (Ti/C>=5), 0.001-0.005% B and the balance Fe. The steel material is hot rolled at about 850 deg.C finishing temp. And coiled at 500-600 deg.C to manufacture a hot rolled steel sheet for enamel. |
