摘　　要：针对马鞍山钢铁股份有限公司CSP生产线7机架连轧机轧制MGW1300电工钢产品时出现的轧制力设定值与实测轧制力误差较大的问题,对影响轧制力的主要因素——变形抗力进行了研究,提出通过保证良好的板凸度指标来间接修正变形抗力理论计算值的新方法。首先根据实测轧制力采用西姆斯公式计算变形抗力初始值,然后利用三维有限元模型对变形抗力初始值进行迭代修正,使板凸度误差达到5%以内。现场应用表明,在MGW 1300产品轧制过程中,用该方法得到的变形抗力修正值,提高了在线轧制力预设定模型的预设定精度,减小了厚度波动,改善了板形质量,为电工钢稳定生产提供了保证。When MGW 1300 electric steel product was rolled in seven-stand continuous hot-rolling mill of CSP line,Maanshan Iron Steel Co.,Ltd.,there is larger deviation between setting value and measured value of rolling force.Resistance to deformation is a main affective factor to rolling force and is studied.A new method for indirective correction of theoretical calculation value of resistance to deformation was put forward.Firstly,initial value of resistance to deformation was calculated by Sims formula with measured rolling force.Then,iterative correction of initial value of resistance to deformation was carried out by use of 3 dimensional finite element model to make crown of strip reach to less than 5%.Practical application showed that after corrective value of resistance to deformation gained by the method was applied to rolling process of MGW 1300 product,control precision of resistance to deformation model and rolling force presetting model was enhanced,thickness fluctuation was decreased,flatness quality was improved and stable production of electric steel was insured.
