以850 mm四辊热连轧机组为研究对象，建立了轧辊辊间接触压力和板形计算模型，以均匀辊间接触压力分布和带钢板形良好为目标，对热连轧机精轧机组支承辊辊型曲线进行了多目标优化设计。理论计算表明，优化后的支承辊辊型曲线均匀了辊间接触压力分布，降低了辊端接触压力峰值，同时能够提高弯辊力对板形的控制效果。工业生产试验后正式推广使用，支承辊掉肩和掉肉现象得到了有效遏制，带钢板形良好。
以850 mm四輥熱連軋機組為研究對象，建立瞭軋輥輥間接觸壓力和闆形計算模型，以均勻輥間接觸壓力分佈和帶鋼闆形良好為目標，對熱連軋機精軋機組支承輥輥型麯線進行瞭多目標優化設計。理論計算錶明，優化後的支承輥輥型麯線均勻瞭輥間接觸壓力分佈，降低瞭輥耑接觸壓力峰值，同時能夠提高彎輥力對闆形的控製效果。工業生產試驗後正式推廣使用，支承輥掉肩和掉肉現象得到瞭有效遏製，帶鋼闆形良好。

Base on the 850 mm 4-Hi hot continuous rolling mills , the models of the contact pressure be-tween rolls and the strip shape calculation were established .Both contact pressure well-distributed between rolls and strip shape control quality were prior target , the back-up roll shape curve of finish stands were multi-objective opti-mized designed .Theoretical calculation show that after optimization the contact pressure distribution between rolls was more uniform , the edge peak value of contact pressure between rolls were reduced , and the strip shape control effect was better .The industrial practice show that the spalling of roll surface was prevented , the control effect of strip shape was improved , the strip flatness was good .
