or (10) calculation, 3 Zhouyi Miao et al: tube drawing process design calculation made ! is a comprehensive approach. Obtained by the calculation of 6, S. The similarity between the values, larger than the D value of 4.2 D and △ D. from , Or S, and ds; isolation, analysis, though both are pretty much the same, difficult to distinguish good and bad. But from the value (see Table 3) to analyze the problem exposed the calculation b, d and e, are undesirable. Because they value each pass of the hill. Almost the same value,[link widoczny dla zalogowanych], did not reflect \. Approach a value of each pass mounds, have shown a decreasing distribution,[link widoczny dla zalogowanych], but not too much difference before and after, unable to take full advantage of drawing the first few channel characteristics of metal plastic is relatively high, so the calculation method a calculation is flawed c and f can reflect the above principles and practices of that experience, but the process of calculation cumbersome computation c, and therefore undesirable. 5 Conclusion (1) 6 calculation methods. . K method is optimal. (2) K. . I 【s method is simple and easy to master. (3) the use of Kn. Law, can get better production practices consistent with the calculated results. (4) △. And △ values of some qualitative regularity: two annealed between drawing passes and more, smaller values; tube material hardening speed, the value of the appropriate larger. (5) to use. △ K method to control the mix of population and △ s for the benefit of improving the quality of finished tubes.
