유한요소법에 기초한 열연중 탄소성을 고려한 압하력 정밀 예측 온라인 모델

Abstract

In this paper, we present finite element (FE) models of the analysis of 2D elastic-plastic deformation of steel. On-Line prediction model which calculate roll force of finishing mills was built based on the results of plane strain, elastic-plastic finite element process model. We proposed the hypothetical mode of rolling, because On-Line prediction model with front and back tension in hot strip rolling. On-Line model’s front and back tension is examined through comparison with predictions from a finite element process model over the various process conditions.
