通过实验手段获取Q235在高温下的应力应变曲线，同时对Q235变形抗力经验模型进行了相关修正，采用多元回归的方法建立了H型钢连轧过程中万能轧机以及轧边机的轧制力数学模型，并给出了3种规格对H型钢连轧轧制力模型的回归系数。通过与实际轧制力对比验证后表明：模型的误差控制在5%以内，计算精度能够满足工程设计需要，可为轧制工艺参数的制定提供一定的参考。

The stressstrain of Q235 in high temperature was obtained though thermomechanical test, and experiential deformresistance model was modified with aid of data from the test, multilinear regression analysis was adopted to establish model of Hbeam rolling force. The finishingcontinuousrolling force of Hbeam was analyzed. Compared with measured values, the predicted ones show relative error of less than 5% which is sufficient to satisfy the needs of the Engineering design, and it also gives a reference in a practical planning.
