PURPOSE: A method for manufacturing a cold rolled plate for enamel with excellent fish scale resistance and adhesion is provided to secure effective an occulusion position for solid hydrogen with minimizing damage to the cold rolled plate. CONSTITUTION: A method for manufacturing a cold rolled plate for enamel with excellent fish scale resistance and adhesion comprises following steps. A slave containing less than 0.005 weight % of C, 0.05-0.5 weight % of Mn, 0.3-1.0 weight % of Zr, 0.04-1.0 weight % of Al, less than 0.03 weight % of P, less than 0.02 weight % of S, less than 0.005 weight % of N, and impurities is hot-rolled at 800 to 950°C. The hot-rolled steel plate is winded at 550 to 700°C. The steel plate is cold-rolled at the draft percentage of 50 to 90. The cold-rolled steel plate is continuously annealed for more than twenty seconds at 700 to 900°C. [Reference numerals] (AA) Micro void; (BB) Fe-Zr metal compound |
