A method for producing sheet steel which comprises the steps of producing a crude bar by rough rolling, subjecting the crude bar to finish rolling, to produce a steel belt, subjecting the steel belt to primary cooling and secondary cooling, and winding up the resultant steel belt after the secondary cooling, wherein the primary cooling is carried out with a cooling rate greater than 120 DEG C/sec down to a temperature of 500 to 800 DEG C and the secondary cooling is carried out with a cooling rate less than 60 DEG C/sec. |
