【Abstract】 Using improved finite element method, the varying rules of rolling-moment during rolling process was analyzed systematically;the influence rule of technical parameters on rolling-moment was also clarified. In addition,the testing system of rolling-moment by using computer-collected data was developed.Through this testing system,the affection rule of rolling-moment at different stretching angle was tested on line.The results of test corresponds with the theoretic analysis.The research results provide important theory foundation for defining parameters of force and energy for developing heavy cross wedge rolling mill.更多还原
