What are the methods to reduce slag inclusions in precision castings?

Slag inclusions in precision castings are defects caused by improper casting processes, resulting in white or black-gray spots on the surface of precision castings. This phenomenon is called slag inclusions. Therefore, we need to avoid this slag inclusions, we need Improve the casting process.

Next, we will introduce methods to reduce slag inclusions in precision castings:

1. If the charge of precision castings is not clean, excessive residues and impurities will enter the precision castings, resulting in a decline in the quality of precision castings;

2. Poor design of the precision casting pouring system will also cause residues to appear during the pouring process of precision castings;

3. When pouring precision castings, if residue is brought into the molten steel, it will also cause slag inclusion in the precision castings, resulting in quality defects.

Therefore, in order to reduce the slag inclusion phenomenon in precision castings and improve the quality of precision castings, we need to improve your production process.
