Prediction Of Strip Temperature For Hot Strip Continuous Mills

In the hot rolling, the strip temperature affects the distribution of the rolling mill load, the finishing plate thickness precision and structure performance. . An accurate prediction of plate temperature changes is importance base of effectively improving the finishing properties. The study of the strip temperature prediction model has been one of the importance researches to improve the mathematics model prediction precision. The foundation of the temperature prediction model and the development of the software system can effectively adapt the requirement of the diversification and high quality of strip property, the simplification of the product design, the improvement of productivity, the reduction of the cost and the improvement of the product property.According to WL510, this paper develop several temperature models and using these models, this paper describe the WL510 strip temperature changes during the hot rolling and computer the temperature distribution through the strip by the one dimension finite difference method. The validity of model predictions has been tested against in-plant measurements. Based on this, this paper develops the temperature modeling prediction system, calculate and analyze the strip temperature according to the various operating parameters. The study is an important part of the steel structure and properties prediction model system and is practically valuable.
