用陶瓷型进行铸造是铸造工艺上的一项先进技术,现在只有苏联及英美等少数国家能够掌握.陶瓷型的优点是:成型方便且快、强度高、能耐高温、膨胀系数小、生产周期短、原料便宜,能多次浇铸和铸造成本低廉.用陶瓷型铸造的铸件表面光洁度可达VV4,又因耐高温,这就适于广精密铸造高熔点的合金钢件,如火箭喷出喷气 Casting with ceramic type is an advanced technology in casting process, and now only a few countries such as the Soviet Union, Anglo-American countries can master ceramic type has the advantages of convenient and fast forming, high strength, high temperature resistance, small expansion coefficient and short production cycle , Cheap raw materials, can be cast and cast a number of low cost. Casting with ceramic surface finish of up to VV4, and because of high temperature, which is suitable for wide precision casting high melting point alloy steel parts, such as rocket jet
