Due to the significant shortening of stainless steel precision casting compared to cast iron, in order to avoid the defects of shrinkage and porosity in castings, methods such as risers, cold iron, and subsidies are mostly used in the casting process to achieve sequential solidification.
To avoid the defects of shrinkage, porosity, porosity, and cracks in stainless steel castings, it is necessary to ensure uniform wall thickness, avoid sharp corners and right angle structures, add sawdust to the mold sand, add coke to the core, and select hollow cores and oil sand cores to improve the concession and permeability of the sand or core.
