The quality of alloy steel castings determines their performance, and it is necessary to improve their quality during the production process. How can manufacturers improve the quality of this product? Mainly through the following points to improve.

1. Reasonable selection of raw and auxiliary materials, correct formulation and strict implementation of relevant process procedures.

2. Adopting new technologies, processes, equipment, and materials.

3. In the casting of alloy steel castings, high hardness and high uniformity molds are used to develop and promote corresponding processes and equipment.

4. Develop new processes and technologies for liquid metal treatment and purification, and optimize material properties.

5. During bonding, two additional tension ribs are installed at the 220mm opening on the inclined surface of the shell. When bonding the ribs, check and proofread the opening size of 220mm to meet the requirements.

6. Mold structure design. If the curved plate is made separately and then bonded to the open dustpan, the mold structure is very simple, but the deformation will be greater. In order to reduce deformation, the overall pattern is made. Although there are two more inclined core pulling on the convex mold, which makes the structure more complex, the deformation of alloy steel castings can be reduced. At the same time, a 15mmx20mm reinforcing rib was added below the easily deformed curved plate, and the transition radius between the curved plate and the main mold was increased from 0mm to 30mm.

7. Properly reduce the sand loading speed and vibration acceleration when the loose sand is solid.

8. When forming the foam pattern, multi gun press feeding is adopted, and the water spraying amount of the upper and lower cooling water pipes is adjusted to make the upper and lower cooling of the mold uniform; Negative pressure dehydration, the shape is fixed in the mold; Multi point vacuum suction cup mold taking.

During the production process, alloy steel castings must strictly comply with standard requirements in order to ensure their quality. Of course, in practical operation, we need to comprehensively consider various factors to improve the quality of the product. Only by mastering the above content can we improve quality.
