Customized cast steel parts: High quality cast steel parts should have clear contours, precise dimensions, dense structure, and small grain size.
1、 Requirements of alloy casting performance on casting structure
1. The wall thickness of cast steel parts should be reasonable
Firstly, ensure the requirement of alloy fluidity, and then consider minimizing the wall thickness of cast steel parts as much as possible.
2. The wall thickness of cast steel parts should be as uniform as possible at all locations
At the hot junction, defects such as shrinkage, porosity, and coarse grain size are easily formed.
3. The wall connection should be reasonable
(1) There should be structural rounded corners;
(2) The boundary between the thickness of the wall should have a reasonable transition;
(3) Wall connections should avoid crossing and sharp angles;
4. The thick wall of cast steel parts should consider the convenience of shrinkage repair;
5. Steel castings should avoid large horizontal surfaces as much as possible;
6. Avoid obstruction during shrinkage of cast steel parts.
2、 Requirements of Casting Process for Steel Casting Structure
1. Simplify the structure of steel castings and reduce parting surfaces;
2. Try to make the parting surface as straight as possible;
3. Try to avoid using movable blocks during styling;
4. Minimize or avoid using cores as much as possible;
5. Vertical walls consider structural slope;
6. Consider fixing, venting, and cleaning the core.
