本文以延伸机本身所固有的一些工艺和性能上的力学问题,例如管口扩大和偏心校正等为目标,研究了三辊斜轧延伸工艺,并报道了一台按比例缩小的、进行热轧钢管试验的实验轧机.文中研究了用于下列目的的实验分析技术:(1)降低偏心和抑制管头管尾口径扩大的实用方法;

In this paper, the extension of the machine itself, some of the process and performance of mechanical problems, such as nozzle expansion and eccentric correction as the goal, studied the three-roll oblique rolling extension process, and reported a scaled down, hot-rolled Experimental Mill for Steel Tube Tests Experimental techniques for the following purposes are studied: (1) a practical method of reducing eccentricity and suppressing the enlargement of the tube end taper diameter;
