摘　　要：介绍了一种用于生产方形、矩形和其他无对称轴断面异型钢管的成型新方法-推轧成型法。分析了采用该方法时钢管的变形特征。实践表明，该方法具有可以生产较高精度的大规格厚壁异型钢管的特点。Described in the article is a new process for producing square, rectangular steel tubes and other non-sysmmetric sectioned shaped steel tubes, the push-rolling torming process.The deformation characteristics of steel tube being rolled with the said process are analysed. Relevant operational practice has proven that the said new process is advantageous in producing largesized and heavy-walled shaped steel tubes with higher accuracy.
