Blow hole defect of wet molding clay sand steel casting

The blow hole defects produced by wet molding clay sand cast steel process are mainly intrusion blow hole and precipitation blow hole. Intrusive blow hole defect is that gas intrudes into liquid metal from the outside, mainly from molding sand, core sand, cold iron, etc., or may be involved...

Casting numerical simulation software database

Casting material database system is an indispensable part of casting simulation software. For a complete set of numerical simulation software, the completeness of the material content in the database, the reliability of the data, the data manipulation function of the database and the smoothness of the connection between the...

Check sand casting

Sand casting fillet is directly related to the internal and external quality of products. At the joint, if the fillet is set unreasonably, it will lead to slow solidification speed and easy to produce defects such as crack, deformation, shrinkage cavity (looseness), sand sticking and so on. After consulting...

Prediction of shrinkage porosity and cavity defects in castings

After years of development, the prediction criterion of shrinkage porosity and shrinkage defects of steel castings has reached a high level in terms of accuracy and application range, which can effectively predict the shrinkage porosity and shrinkage defects in casting steel. At present, most simulation software at home and...

Avoid shrinkage cavity and porosity defects of steel castings

Many parts of construction machinery such as bulldozers and excavators are cast steel castings, which often have shrinkage defects. Light shrinkage and porosity will increase the cost of repair and inspection, and heavy shrinkage and porosity defects will lead to the scrapping of steel castings. Combined with the actual...

Shrinkage cavity and porosity defect of steel castings

The defects of shrinkage cavity and porosity are briefly introduced. Combined with the theories of filling capacity of liquid metal, solidification mode of steel castings and shrinkage of steel castings, the process design of traditional steel castings is carried out by taking the accessory bracket of a construction machinery...
