shrinkage porosity

基本解释

Shrinkage and shrinkage porosity, stress and deformation often occurs during the production of heavy steel casting.
大型铸钢件在实际生产中易产生缩孔缩松、应力变形等缺陷。
And the shrinkage porosity distribution in the castings and the mechanical properties of the castings were also researched.
研究了铸件中的缩松和铸件力学性能分布特点。
The results showed that good purification effects can be obtained, in which not only major coarse impurity particles was removed but also shrinkage porosity was effectively abated.
研究表明，该方法可以实现良好的净化效果。不仅过滤了绝大多数粗大夹杂物，而且对减少显微缩孔十分有效。
