| 不锈钢铸件生产工艺 Production technology 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 make a fusible model (referred to as investment model or model) from fusible materials (such as wax or plastic), coat it with several layers of special fire-resistant coating, dry and harden it to form an integral mold shell, then melt the model from the mold shell with steam or hot water, and then place the mold shell in a sand box and fill dry sand around it for modeling, Finally, put the mold into the roasting furnace for high-temperature roasting (for example, when using high-strength mold shell, the mold shell after demoulding can be directly roasted without modeling). After roasting, the mold or mold shell is poured with molten metal to obtain the casting. |
