为了有效提高宽厚复合板热轧成形质量，以不锈钢与低合金钢层状复合结构材料为研究对象，针对宽厚复合板结构复合及加工协同变形的技术要求，制定宽厚复合板热轧成形工艺路线，并对热轧宽厚不锈钢复合板成形轧制力模型进行研究。将热轧复合变形区分成Ⅰ、Ⅱ两个区段，并依据热轧过程中轧制区间内金属流动变形规律，确定各界面上摩擦切应力子的方向，进而推导出热轧不锈钢复合板成形轧制力计算公式。研究结果表明：该轧制力模型可准确预测轧制力的大小，有效提高轧制力的计算精度。经轧制成形制造的不锈钢复合板满足设计技术要求，制定工艺路线合理，可用以指导生产实践。

To effectively improve wide-thick clad plate hot rolling forming quality, stainless steel and low alloy steel laminated composite structure material were taken as the subject, wide-thick clad plate hot rolling process was formulated according to the technical requirements of wide-thick clad plate structure composite and collaborative deformation processing. The hot rolling composite deformation area was divided into two sections marked I and II. Based on metal flowing deformation rule during hot rolling process, the directions of frictional shear stress τ on each interface were determined and rolling force calculation formulas of hot rolling stainless steel clad plate were derived. Results show that the rolling force model can accurately predict the rolling force and effectively improve the calculation accuracy of rolling force. The stainless steel clad plate after hot rolling forming manufacturing meet the technical requirements and the formulated process route is reasonable, which can be used to guide the practical production.
