Analysis of casting defects of dual phase steel pump casing

The single suction pump casing is a box type casting, and its structure is shown in the figure. Casting defects are mainly divided into two categories, namely, internal shrinkage defects and inclusion defects. Firstly, the internal shrinkage defect is analyzed. The main wall thickness of the research object is...
