The method forms the aluminum killed steel that is consisted of under 0.01 weight% of C, 0.1 to 0.4 weight% of Mn, 0.03 to 0.09 weight% of S, 0.04 to 0.1 weight% of Ti, and under 0.005 weight% of N are contained and atomic ratio that is defined with Ti/(C+N+0.2S) is controlled to more than 1 and the rest contains Fe and other inevitable impurities. The formed aluminum killed steel is hot rolled at the end by setting the finishing rolling temperature above the Ar3 critical point and after winding it within the conventional temperature range, cold rolling it with 50 to 80% of draft percentage. Produce the cold rolled steel plate with excellent enamel adhesive by continuing annealing it next.
