PURPOSE: A method for preventing surface roughness of thick cold rolled plate during forming is provided, which is characterized in that grain size of final product is controlled finely to prevent orange peel. CONSTITUTION: The method is characterized in that a steel sheet is hot rolled at 750 to 800°C; the hot rolled steel sheet is coiled at lower than 400°C; the hot coil is cold rolled; and the cold rolled steel sheet is annealed at 680°C for 10 hrs.
