铁型覆砂铸造是在金属型内腔覆上一薄层型砂而形成铸型的一种铸造工艺,兼具有金属型和壳型铸造的特点。对轮盘的铁型覆砂铸造成形过程进行了数值模拟,获取了铸造填充过程的基本参数。对铸造过程可能产生的缺陷进行了分析,预测了铸件的缩孔、缩松等。相关结论在实际生产中得到了很好的印证。 Iron Sand Mold Casting is a casting process in which a thin layer of sand is overlaid on a metal type cavity to form a mold, which is also characterized by metal type and shell type casting. The process of iron sand casting process was simulated and the basic parameters of casting process were obtained. The casting process may be the defects have been analyzed to predict the shrinkage of castings, shrinkage and so on. Relevant conclusions in the actual production has been well confirmed.
