熔模精密铸造近年来在国内外得到了迅速的发展,可以认为已经是一种比较成熟的工艺了。但是,由于影响熔模精密铸造的工艺参数甚多,就国内现在的情况来说,有效地控制各种工艺参数还存在许多困难,因而影响了产品的质量与成本,阻碍着熔模精密铸造的进一步发展及应用。这样,对于型壳的性能进行测试与研究就成为一个重要的课题。我们教研室1975年制成的精密铸造型壳高温强度试验机,
Investment casting in recent years at home and abroad have been rapid development, can be considered already a more mature technology. However, due to a large number of process parameters affecting investment casting, the current situation in China, there are many difficulties in the effective control of various process parameters, thus affecting the quality and cost of the product, hinder the investment casting Further development and application. In this way, the performance of the shell to test and study has become an important issue. Our teaching room made in 1975 precision casting shell high temperature strength testing machine,
