Development of an On-Line Model for the Prediction of Roll Force and Roll Power in Roughing Mill by FEM

유한요소법을 이용한 조압연에서의 압하력 및 압연동력 예측 온라인 모델 개발

In this paper on-line model is derived from investigating via series of finite element process simulation. Some variables that little affect on non-dimensional parameters. ie. forward slip and torque factor. is extracted from composing on-line model Especially, this research focused on deriving on-line model which exactly predict roll force and roll power in the roughing mill process under small shape factor and small reduction ratio. The prediction accuracy of the proposed model is examined through comparison with predictions from a finite element process model
