液态挤压铸件工实践本文所谈“液态挤压铸造工艺”是一种铸锻相结合的先进工艺。是把液态金属注入金属型腔,然后对该腔内液态金属迅速加压成型,并在压力下结晶和少量塑性变形,故又称为“液态模锻”。液态挤压铸造自从问世以来,已有40多年历史,但长期不为重视,近年来国外在运输机械、航空及兵器等生产领域有了广泛应用,在苏联已成为普通生产工艺,我国自廿多年前开始研究,但发展速度是不够快的,直到目前为止也只有三、四十个厂家,在上 Liquid extrusion casting workers practice This article talked about “liquid extrusion casting process” is a combination of advanced casting and forging process. Liquid metal is injected into the metal cavity, and then rapid cavity liquid metal pressure forming and crystallization under pressure and a small amount of plastic deformation, it is also known as “liquid forging.” Liquid squeeze casting has been in existence for more than 40 years since its publication. However, it has not been paid much attention in the long term. In recent years, foreign countries have been widely used in the fields of transportation machinery, aviation and armament, etc. In the Soviet Union, it has become an ordinary production process. Since 20 years Before starting to study, but the pace of development is not fast enough, so far only three or forty manufacturers, on the
