随着铸造技术的迅速发展 ,以及对铸件机械性能和尺寸精度等要求不断地提高 ,如何获取近净形铸件的需求越来越强烈。因此生产近净形铸件的技术层出不穷 ,其中 SC( ShellCasting壳型铸造 )和 FC( Freeze Casting冷冻铸造 )就是这一大家族中的两个重要成员 ,是精密铸造发展的一个重要方向
With the rapid development of foundry technology, as well as the continuous improvement of mechanical properties and dimensional accuracy of castings, there is an increasing demand for obtaining near-net shape castings. Therefore, the production of nearly net-shaped casting of endless technology, including SC (ShellCasting shell casting) and FC (Freeze Casting frozen casting) is the two major members of this family is an important direction for the development of precision casting
