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,ugg stivali, did not reflect \. Approach a value of each pass mounds, have shown a decreasing distribution,stivali ugg, 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.
