Fusion modeling of the hot mill based-on case-based reasoning

In view of the existing problems of poor adaptability for the small special steel grade modeling，based on the research of the foundation and optimization of existing hot mill model，a fusion modeling aiming at the small special steel grade in hot strip mill based on case-based reasoning was proposed combined with the mechanism-theory formula and advanced model control technology. According to the condition characteristics of small special steel grade，the model establishing process of the special steel grade rolling in hot strip mill with case-based reasoning was explained in details. With the practical production experience，this model has got continuous optimization，and the proper control parameter has been confirmed. This fusion modeling method can effectively enhance the control precision of the small special steel grade rolling and enhance the product quality.
