Large diameter square tube defects

Many large diameter square tube defects are caused by the perforation in square and rectangular tube, so the mass production of large diameter power process is the key process square tube.

Perforation main difficulty lies in the low alloy high performance perforation, when necessary in order to ensure the quality of the deformation parameters of rational choice perforation.

大直径平方管少量压缩会导致不稳定的穿孔过程，因此，关键压缩儿童的头应为通常设定的第一个压缩，否则即使在添加或移动卡之前，它也不会咬人。在腔体内部会形成越来越多的压缩量的前面，并且陈成缺陷，因此，如果您想克服问题，则管子也居中，居中，深度和空间以根据其他钢进行比较。加热系统在加热温度和质量要求上的方式也是如此。加热的质量在很大程度上取决于加热操作和加热系统。系数相对较小的值通常是有利的椭圆形，可以改善头发的质量，并可能限制横管变形。但是，也不会太小的椭圆形系数，这会导致滚动旋转困难，甚至导致指南的磨损，也可能在表面造成缺陷。

Tie the boat when the large diameter square tube should generally check the wear guides, once discovered, immediately replaced, should control the degree of the ellipse inside the 1.07-1.08 range. After the normal process steps as well as the impact of large diameter square tube heating tube key processes, which affect the quality of the finished product is also very large.
