center porosity

基本解释

Center segregation and center porosity will seriously affect the internal slab quality for continuous casting bloom.
连铸过程中出现的铸坯中心偏析和中心疏松会严重影响铸坯内部质量。
The center axis of the part has inclusion defects as well as porosity and thus is suitable only for parts where this can be machined away.
零件的中心轴附近存在缺陷和孔隙，因此仅适用于能将这些机加工去除的零件。
But several defects are usually found in the continuous casting of steel, such as center segregation, V segregation and central porosity, especially for high carbon steels.
但在高碳钢连铸中，往往容易产生中心偏析、V形偏析、中心疏松等问题。
