摘　　要：以C++编程语言为开发平台,以圆钢棒材减定径轧制为基本实体模型,选择相应的变形抗力、宽展、轧制力、轧制力矩等计算模型编制工艺参数计算源程序。采用有限元仿真软件Deform-3D对轧制过程进行模拟,修正了程序中的计算模型。重点分析了伸长率对宽展的影响,修正了采利柯夫宽展等效计算模型。最终,以Ф16 mm圆钢为例,通过软件计算、有限元模拟以及现场数据,对比了宽展量、出口断面面积以及轧制力。结果表明软件分析结果与实测值、模拟值比较吻合,从而验证了软件计算结果的准确性。With the C ＋ ＋ programming language as the development platform and the reducing and sizing rolling of the round steel bar as solid model,the source programs for calculating the process parameters were proposed by selecting the corresponding calculation models,which included deformation resistance,spread,rolling force,rolling torque etc. In order to revise the calculation model in the program,the rolling process was simulated by Deform-3D software. The influence of elongation on spread was emphatically analyzed,then,the empirical formula of spread model was revised. Finally,taking the Ф16 mm round steel as an example,the amount of spread,sectional area of outlet and rolling force were compared by software calculation,finite element simulation and field data. Results show that the calculations of the software are in good agreement with that of the field data and simulation,which verifies the accuracy of the program calculation.
