精密钢管是如何进行校直的?

第一,济南镀锌管精密钢管曲折是因为轧机调整不妥,轧制时残留的剩余应力以及因为沿管子截面和长度上冷却不平等缘由形成的。因而,不行能从轧机直接得到很直的管子,只要通过冷校直管子的曲折度才干满意技能条件的规则。

First, the zigzag pipe of Ji'nan galvanized pipe is tortuous because of the improper adjustment of rolling mill, the residual stress during rolling and the reason of cooling unequal along the section and length of pipe. As a result, a straight tube can not be obtained directly from the mill, so that the rules of the skill condition can be satisfied only by the zigzag of the cold straightening tube.

第二,校直的根本道理即是使精密钢管进行弹塑性曲折,由大的曲折度成为小的曲折度,因而钢管在校直机内有必要遭到重复曲折。济南镀锌管钢管重复曲折的程度主要由校直机的调整所决议。

Second, the fundamental principle of straightening is to make the precision steel pipe elastic-plastic and tortuous, and become a minor tortuosity from large tortuosity, so it is necessary for steel pipes to be subjected to repeated twists and turns in the straightening machine. The degree of repeated twists and turns of the Ji'nan galvanized pipe is mainly determined by the adjustment of the straightening machine.

第三,影响校直质量的要素许多,如精密钢管的曲折度,钢管尺度和材料校直机型式,调整参数等。用途简介制造锡罐:因锡镀层无毒性,大量用在与食品及饮料接触之物件,中最大用途就是制造锡罐。

Third, there are many factors that affect the quality of the straightening, such as the zigzag degree of the precise steel pipe, the scale of the steel tube and the type of material straightening, the adjustment of the parameters, etc. The use of tin cans: tin coating is non-toxic, a large number of products used in contact with food and beverage, the largest use is to make tin cans.
