How to reduce the defective rate of stainless steel castings

I will explain to you how to reduce the defective rate of stainless steel castings

How to reduce the defective rate of stainless steel castings? The following are specific methods to reduce the defective rate of stainless steel castings:

1) Large flat surfaces in castings should be minimized;

2) The casting holes on the inner wall of the casting plan should be reinforced with a convex edge structure to reduce the wall thickness;

3) The casting structure should be closed as much as possible during refrigeration;

4) Large-scale cavities such as internal water channels and gas supply in castings should have multiple connecting columns.

5) The connection between the casting wall and the middle wall should be resolute to prevent bevels and the accumulation of metal materials. The connection between thick-walled pipes and thick-walled pipes should be slow, resolutely prevent sudden changes, prevent thermal joints and force concentration, and produce thermal cracks, shrinkage, etc.

6) For some thick cross-sections of castings, hollow or cast-hole structures should be selected as much as possible, and appropriate structural reinforcement with lifting ribs;

7) The thickness of stainless steel castings should be symmetrical to avoid shrinkage cavities and hot cracks. When it is necessary to ensure sequential curing standards, it should be as thick as possible in one direction. When it is necessary to ensure other curing standards, it should be as possible as possible. Equal section wall.
