4.Conclusions
In this paper,a parametric investigation on the defect phenomenon together with the theoretical nalysis and the finite element formulation for the CONFORM process is presented.For the parametric analysis,the five significant process parameters were examined.From the numerical results,it is observed that the wheel velocity does not affect the separation phenomenon while the other parameters do.The friction coefficient and the relative flash gap are directly related to the material flow ratethrough the flash gap and exhibit almost the same effect,the increase in restraint upon the defect in proportion to their
magnitudes.On the other hand,the relative abutment height restrains the defect occurrence according to its increase while the extrusion ratio facilitates its increase.
Furthermore,the limiting extrusion ratios are suggested with respect to the other process parameters such that the process can extrude products without the internal defect.

结论
本文中,对缺陷现象的参数探究和理论分析以及对CONFORM过程的有限元素公式均进行了表述.在参数分析中,对五个重要的处理参数进行了检验.从数据结果发现,转轮速度并不像其他参数一样会影响分离现象.摩擦系数和相对炽焰间隙直接与通过炽焰间隙的物质流量率有关,并且会产生相似的影响,即对缺陷产生的抑制作用的增加与其强度呈现比例关系.另一方面,相对支座高度的增加会抑制缺陷发生率,同时挤压比会加速缺陷增加.此外,对于其他处理参数而言,限制挤压比表明在处理过程中可以发现没有内部缺陷的产品.
