Intelligent prediction of rolling force in hot rolling based on a multi-model and weighted support vector machine
摘要
Abstract
In order to improve the set accuracy of rolling force for a finishing mill in the hot rolling process, high precision predic-tion of rolling force is very important. In this paper, an approximate value of rolling force is calculated through theoretical formulae. And then, a correction coefficient of rolling force is computed using big field data. Firstly, different product states are classfied by the clustering method. Secondly, the correction coefficient is computed based on a weighted least square support vector machine. Through a combination of these two results, the rolling force value with high precision is predicted. The average relative prediction error of roll-ing force is 3. 2%, which can meet the requirements of field production.关键词
