A large ductile iron bearing cover casting process design
A large spherical bearing cover casting process is briefly introduced,aiming at the shrinkage porosity defects that usually occur in large ductile iron bearing covers,the built-in sand core+cold iron,adjusting the material composition,and designing the filter slag removal system are adopted,which eliminates the defects such as shrinkage porosity and slag inclusion,improves the casting yield rate,and reduces the processing cost.
