摘　　要：采用几何模拟方法,实测了实验轧机上轧制铅棒的前滑值。在分析影响前滑因素的基础上,建立了椭进圆和圆进椭轧件前滑回归模型。利用该模型预测了某连轧棒材厂轧制φ12 mm,φ16 mm圆钢时各道次轧件的前滑值,较准确地确定了其连轧常数和速度制度。结果表明,该模型精度较高,这对正确设计连轧棒线材中精轧机组的轧制程序表,进而保证连轧过程顺利进行具有较大的实用价值。With geometric simulation, forward slip values of Plumbum bar rolled are measured in the experiment mill, and based on the analysis of influential factors on forward slip, regression forward slip models of oval-round and round-oval workpiece are established. Forward slip values of every pass are predicted for-12 mm and -16 mm round bar rolling in a bar tandem rolling factory, and tandem rolling constant and speed system are determined. The result indicates that the models have high precision, valuable for accurate design of rolling schedules and ensuring success of bar rolling and wire tandem rolling.
