PURPOSE: A method for producing a cold rolled enamel steel sheet with high strength is provide to have excellent fish scaling resistance and adhering property, to be produced in a short time, and not to require for adding separate alloy element, such as Cu. CONSTITUTION: A steel is composed of 0.02-0.06wt% of C, 0.3-0.5wt% of Mn, under 0.012wt% of S, 0.02-0.04wt% of Al, under 0.01wt% of O, 0.005-0.015wt% of N, 0.05-0.15wt% of V, and the remnant wt% of Fe and impurities. Then, the steel is cogged and hot rolled in a direct rolling process of thin slab. And, the steel is wound up at a temperature of 600-700°C for being washed in acid. The steel is cold rolled at a draft percentage of 60-80%. And, the steel is annealed at a temperature within a re-crystalline temperature and 850°C. Therefore, a cold rolled enamel steel sheet with high strength is completed.
