精密铸造是铸造行业中较优异的工业技术,它不仅可以铸造各种合金铸件,而且所得铸件的尺寸精度及表面光洁度均较高,是获得形状复杂,少加工或无加工切削金属零件的优异铸造方法。它的铸造工序较复杂,其中模壳的焙烧是必不可少的工艺步骤。型壳经高温焙烧后可驱除挥发性物质,进一步提高型壳的质量,对某些型壳还能起到矿化及烧

Precision Casting is the foundry industry superior industrial technology, it can not only cast a variety of alloy castings, castings obtained and the dimensional accuracy and surface finish are high, is to obtain the shape of complex, less machining or machining of metal casting excellent casting method. Its casting process is more complicated, in which the mold shell baking is an essential process step. Shell after firing at high temperatures can get rid of volatile substances, to further improve the quality of the shell, the shell can also play some of the mineralization and burn
