不锈钢铸件生产工艺
Production process of stainless steel castings
所谓熔模铸造工艺,简单说就是用易熔材料(例如蜡料或塑料)制成可熔性模型(简称熔模或模型),在其上涂覆若干层特制的耐火涂料,经过干燥和硬化形成一个整体型壳后,再用蒸汽或热水从型壳中熔掉模型,然后把型壳置于砂箱中,在其四周填充干砂造型,最后将铸型放入焙烧炉中经过高温焙烧(如采用高强度型壳时,可不必造型而将脱模后的型壳直接焙烧),铸型或型壳经焙烧后,于其中浇注熔融金属而得到铸件。
The so-called investment casting process is simply to use fusible materials (such as wax or plastics) to make fusible models (for short, fusible models or models), coated with a number of layers of special refractory coatings, after drying and hardening to form a whole shell, then use steam or hot water to melt the model from the shell, and then put the shell in sand. In the box, dry sand moulding is filled around it. Finally, the castings are put into the calciner and roasted at high temperature (for example, when the high strength shell is used, the shell after demoulding can be directly roasted instead of moulding). After roasting, the castings are obtained by pouring molten metal into the castings.
