引 言 熔模铸造是古老的失蜡方法的一个完全新型的变种。由于蜡(蜂蜡)很易于取得并且具有独特的性质,因而使前人能够设计出这种出人意外地复杂的铸造技术:在这种方法中,先是制造出一个模型,然后在生产一个比原有模型价值更高的金属铸件的过程中,将它消耗掉。 目前,虽然我们所知的天然和人工合成材料非常之多,但由于蜡很易于取得并且具有独特的性质,因而它仍然是制造熔模铸件的模型中较受欢迎的基本材料。当然,蜡的 Introduction Investment casting is a completely new variant of the old lost wax method. Because wax (beeswax) is easy to acquire and has unique properties, it has led to the design of this unexpectedly complex casting technique: in this method, a model is first made and then a billet It has been consumed in the process of having a more valuable metal castings. At present, although we know that there are so many natural and synthetic materials, waxes are still the most popular basic material for making investment casting molds due to their ease of acquisition and their unique properties. Of course, the wax
