| 不锈钢铸造不仅适用于各种类型、各种合金的铸造，而且生产出的铸件尺寸精度、表面质量比其它铸造方法要高，甚至其它铸造方法难于铸得的复杂、耐高温、不易于加工的铸件，均可采用熔模精密铸造铸得。 Stainless steel casting is not only suitable for the casting of various types and various alloys, but also the size accuracy of the castings and the surface quality are higher than those of other casting methods. Even the other casting methods are difficult to cast, and the casting can be cast by precision casting. 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 melt casting process is simply to make a melted model (such as a wax or a plastic) to make a melted model (called a melt or model). It is coated with a number of specially made refractory coatings. After drying and hardening a monolithic shell, the model is melted from the shell with steam or hot water and then the shell. In the sand box, the molding of dry sand is filled around it. Finally, the casting mold is baked in a calciner through high temperature roasting (if the high strength shell is used, the mold shell can be calcined directly without the mold). The cast or shell is roasted, and the molten metal is poured into the casting to get the casting. |
