Abstract：Aiming at the problem of the large roll consumption and the roll spalling and roll crapping of about a domestic 1 420 cold continuous rolling mill，and even the problem of roll spalling and roll crapping，a general method for the design of cold roll profile was established. Then combined with the equipment and technology feature of cold rolling mill，a set of roll shape curve parameters optimization the model was designed for optimizing the roll shape curve parameters in set up for cold continuous rolling mill. And a new type of the new back- up roll profile and middle roll profile were designed，which can reduce the roller pressure distribution of the uneven degree simultaneously and adjust the effect of bending roll force. It was applied to in the production practice of the 1 420 cold rolling mill，which reduced the roll consumption and the incidence rate of crapped roll，improved the product quality，enhanced the brand competitiveness，and brought benefits to the enterprise.
