摘　　要：介绍了辊模拔制异型钢管的特点，进行了辊模拔制和固定模拔制试验。试验证明，辊拔工艺可显著降低拔制力，提高异型钢管表面质量。The paper deals with features of roll-die drawing of shaped steel tubes and experiments of roll-die drawing and fixed-die drawing. The said experiments show that with the roll-die drawing process the drawing force can be considerably reduced and surface quality of the shape steel tube improved.
