摘要
文章认为，压力对于减少铸件中的气孔、缩松，细化晶粒，减轻铸件的热裂倾向，降低力学性能对浇注温度的敏感性，提高铸件力学性能及力学性能的均匀性等有重要作用。
AbstractIt has been considered that pressure has important effect on factors such as reducing porocity and dispersed shrinkage,grain refinement,reducing hot tear tendency of casting,lowing sensibility of mechanical properties to pouring temperature,improving mechanical properties and performance homogeneous.
