PCT No. PCT/KR95/00167 Sec. 371 Date Aug. 19, 1996 Sec. 102(e) Date Aug. 19, 1996 PCT Filed Dec. 19, 1995 PCT Pub. No. WO96/19305 PCT Pub. Date Jun. 27, 1996A method for manufacturing a cold rolled steel plate used for enamel applications such as tableware, construction panel, external plate material of microwave oven and gas range, and bathtub, in which an excellent enamel adherence between an enamel layer and a raw steel plate is increased and a formability required for the production of complicated shape is greatly improved and to provide a method for manufacturing a high processing cold rolled steel plate being excellent in enamel adherence. The invention is, in a method for manufacturing an enamel coating cold rolled steel plate by utilizing aluminum killed steel, a method for manufacturing a high processing cold rolled steel plate being excellent in enamel close adhering property in which an aluminum killed steel, in which C: less than 0.01%, Mn: 0.1-0.4%, S: 0.03-0.09%, Ti: 0.04-0.1% and N: less than 0.01% by weight % are contained, and an atomic ratio defined by Ti/(C+N+0.4S) is adjusted to 1.0-2.0, and the remaining part consisting of Fe and other inevitable impurities is included, is hot rolled by making a finish rolling to be finished in a temperature section above the Ar3 transformation temperature, then coiled and afterwards, cold rolled with a reduction ratio of 50-85%, and finally continuously annealed.
