What are the methods to improve the quality of stainless steel precision casting?

Stainless steel precision casting is a casting process with little or no cutting. It is an excellent process technology in the casting industry and its application is very wide. We are all improving the precision casting of stainless steel. Piece quality at that time, what methods do we usually use to improve his quality?

The methods to improve the quality of stainless steel precision casting are as follows:

1 mold planning: the appearance treatment of stainless steel castings starts from the mold at the top of the list, and the appearance of the mold is clean, I .e. the appearance is wiped with sandpaper and then painted with nitro paint, metal or plastic molds are selected for castings with high precision.

2 Process planning: strictly control the process and ensure the appearance and sand core before closing the box. It's a belt temperature condition., ensure the fluidity of the molten steel during pouring, and select Frocco for rough and damaged areas. ISOMOL300 alcohol-based zirconium the powder paint is brushed and then ignited and baked.

3, Fillet planning: In order to avoid white mouth when forging stainless steel, in addition to adopting technical methods, it is necessary to make the wall thickness not too thin, and the wall thickness is15mm in the above case, it is necessary to use rounded corners at the corners of metal forged castings;

4 wall thickness planning: because the metal type dissipates heat quickly, the minimum wall thickness of stainless steel forging should be larger than that of sand forging castings, and the minimum wall thickness of various forging alloys and different sizes should be larger.

53. Polishing planning: remove flash burrs in the polishing process, and polish the uneven surface to over-lubricate. About the heat-treated castings to choose polishing and polishing treatment, steel shot size scale.0.85~1.4mm, hardness HRC40-50.

When we all improve the quality of stainless steel precision casting castings, we can all operate according to the above methods. The correct operation to improve stainless steel precision casting castings is what we all need.
