How to Prevent The Deformation of Steel Castings

What is the reason for the deformation problem of the products produced by the steel casting foundry? This may be a problem in the casting production process, and the main cause of product deformation is thermal stress. The reason for the deformation of most of the casting products is that the structural design is unreasonable when the personnel are designing, the wall thickness is uneven, and the cold cutting is improper and uneven.

So how can we prevent the problem of product deformation, and how can we improve the process of steel casting production?

1. Before pouring, the technicians of the steel casting factory will first set up the inner gate, and the position of the inner gate should be set reasonably, so that the temperature difference can be reduced, and it can also effectively avoid the problem of mutual containment when the casting shrinks.

2. Reasonably increase some process ribs and strong ribs, etc., and improve the structure of steel castings in design.

3. When setting up the gating system, it is also necessary to make some corresponding improvements to the gating system.

4. The steel casting foundry can also change the structure of the product, so that the rotary kiln wheel belt is as symmetrical as possible, and the wall thickness can also change slowly.

5. In addition, we have to change the cooling method and try to make all parts of the product cool evenly.

If the structure and wall thickness of the product produced by the manufacturer are not uniform, then the cooling shrinkage of each part is not the same, and the residual tensile stress will appear in the place where the cooling is slower, and the residual compressive stress will appear in the place where the cooling is faster. In the general stress state, the steel casting products produced by the steel casting factory can be transformed from an unstable state to a stable state, and the casting itself will be deformed to reduce the internal stress.
