Model for the prediction of Roll Force of Roughing Mill considering Width reduction

도그본 고려한 조압연 압연하중 예측모델 개발

Online models predicting roll force and forward slip of roughing mill was developed using nondimensional parameters. Using the effective inlet thickness, roll force model take into account the effect of inlet dog-bone shape of slab which take places after width reduction through edger rolling in roughing mill. The prediction accuracy of the proposed model is examined through comparison with measurements.
