Abstract
The shape of the hot rolled material has a strong influence on the stability of the rolling process and the quality of the product. The crowning and flatness of the strip are the result of the profile of the work roll and the rolling force imposed on the material. This paper presents the development of an application to automatically simulate the entire set-up of the Ipatinga Hot Strip Mill in an offline way for a given rolling program. The simulator was developed based on mathematical and logical formulations of calculations present in the literature and the online control model. In addition to the rolling parameters, the simulator predicts the wear and thermal expansion of the work rolls, allowing the prediction of the profile of the strip and the necessary bending force to obtain the desired shape. The offline model was validated by industrial tests with results very close to the simulated values.
