Abstract

Abstract: The steel plate with large weight or small aspect ratio can be produced by angular rolling technology， which overcome the disadvantage of equipment limitation or low production efficiency derived from multiple turnings. Based on the principle of constant volume and the relationship of trigonometric function， the formula for the pattern and dimension change of the plate are deduced and the relationship between the turning angle and reduction for making the plate rectangular is obtained. A model for predicting the angle， reduction and width spread in angular rolling process is established. The program procedure of pattern prediction for angular rolling process is designed， the width spread calculation is simplified， and a program for angular rolling pattern prediction is developed. The pattern prediction model is verified by the angular rolling experiment. The maximum error between the calculated dimension data and actual rolling dimension data is 6.22 %， which proves that the accuracy of the pattern prediction model for angular rolling process.

Key words: plate; angular rolling; constant volume principle; pattern prediction model; width spread
