摘　　要：从理论和实验两方面分析了现有各种确定型钢轧制宽展变形的方法。其结果表明，现有的各种宽展模型的预报精度不能满足需要。实用的高精度宽展模型必须分不同的孔型系统和轧机布置形式，由现场实验和回归得到。用这种方法，作者得到了３组分别适用于横列式轧机、复二重轧机和连续式轧机轧制简单断面型钢的宽展模型。All kinds of formulae calculating the spread of bar steel rolling have been analysed theoretically and evaluated by experiments.It shows that no one can satisfy the needs of production due to low accuracy.Accurate spread formulae must be studied out by experiments and regression according to different roll passes and different rolling mill layout.By the method,described in the paper in details,a group of spread formulae suitable for open train,double due and continuous bar steel rolling mills has been worked out.
