shrinkage porosity

基本解释

Shrinkage and shrinkage porosity, stress and deformation often occurs during the production of heavy steel casting.
大型鑄鋼件在實際生産中易産生縮孔縮松、應力變形等缺陷。
And the shrinkage porosity distribution in the castings and the mechanical properties of the castings were also researched.
研究了鑄件中的縮松和鑄件力學性能分佈特點。
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，該方法可以實現良好的淨化傚果。不僅過濾了絕大多數粗大夾襍物，而且對減少顯微縮孔十分有傚。
