Abstract

PURPOSE: To lower soluble nitrogen content of a steel plate and to make AlN particles large by hot rolling Al killed steel; coiling the hot rolled plate within a specified temperature range; and carrying out annealing at a temperature lower than conventional one, so as to obtain a cold rolled steel plate with good surface properties and press moldability.
