METHOD FOR FORECASTING ROLL FORCE OF ROUGHING MILL CONSIDERING WIDTH REDUCTION

摘要

The present invention is considering rolling the dog caused by the explosion, opened during the rolling process Roughing device , relates to a method for predicting the load , deriving an effective process conditions Considering the dogbone shape by using the input setting process conditions , and predicting the rolling load for the rough rolling derived from the effective process conditions . By determining the value taken during the rolling load applied to the rolling load prediction by the horizontal rolling when considering the effective inlet cross section of the dog -like inlet thickness and calculating the horizontal rolling load model expression for the effective inlet thickness and rolled considering the dogbone can be predicted load , which results in an effect that can be reduced more than the prediction error of the rolling load rough rolling process .
