摘　　要：介绍一种简便实用的由圆变方的方、矩形焊管的孔型设计方法。本方法采用交替变形法，变形阻力小、轧辊寿命长、成品率高、易于掌握，适于广大中小型焊管厂推广使用。This paper introduces a simple, convenient and practical method of pass design for rolling circular welded pipe into square or rectangular pipe. Alternate deformation is adopted in this method. Low deformation resistance, long roll life, and high rate of finished products are advantages of this deformation process. This design method can be easily learned. It is particularly suitable for small or middle-scale welded pipe mills.
