摘　　要：采用西姆斯公式建立了轧机的轧制力模型，拟合得出了模型中各参数。回归计算了不同钢种的参考屈服应力，分别计算了管线钢经济型X90、深海底管线X70Mo、高建Q420GJC、桥板Q420qE、船板EQ51、锯片钢50Mn2V和高强钢A514Gr．S等钢种的参考屈服应力。By using SIMS formula, the rolling force model was established, the parameters in the model were obtained with fitting method. The reference yield stress of different steel grades, including pipeline steel xg0, deep seabed pipeline steel X70Mo, building structure steel Q420GJC, bridge plate Q420qE, ship plate EQS1, saw steel 50Mn2V and high strength steel A514 Gr. S etc., were calculated respectively by using the regression method.
