带钢平整过程中C翘机理及治理策略
C-warping Mechanism and Treatment Strategies in Leveling Processes of Strip Steels
摘要
Abstract
In order to solve the problems of C-warping defects in strip steels in the leveling proces-ses,the processing parameters in the strip leveling processes were optimized,and a set of C-warping prediction and treatment strategies for strip steels were developed.The formation mechanism of C-warping was analyzed from three aspects:rolling,processing lubrication systems and the influences of anti-wrinkle rollers and anti-trembling rollers on the forces of strip steels.The stress distribution of the horizontal direction of the outlet strips in the thickness was obtained,based on the stress analysis of the strips under the assumption of half-plane infinite body,the maximum and minimum transverse elongation in the thickness direction of the strips were obtained,and the height of the C warp of the strips was obtained through the geometric relationship.A set of optimal height settings of anti-wrinkle rollers and anti-trembling rollers were sought to minimize the objective function of the comprehensive control,and the elongation in the direction of strip thickness was controlled,so as to reduce C-warp.The model and treatment strategies were applied to a leveling unit in China,and the prediction errors of C warping height are controlled within 10％,and the maximum warpage ranges of the unit are re-duced from 1.4～6.5 mm to 0.9～4.5 mm.The results show that the C warpage prediction and treat-ment strategy meet the production demands,and the warpage values are significantly reduced,which reduces the repair rate caused by warpages.关键词
