How to get a good corrosion-resistant copper castings of water pump
- Nov 07, 2018 -

Corrosion-resistant copper castings of water pump need to adopt a reasonable casting process, that is, according to the structure, weight and size of copper castings, casting alloy characteristics and production conditions, choose the appropriate parting surface and shape, core making method, reasonable setting of casting ribs , cold iron, riser and gating system to ensure good casting.


Secondly, the design processability of the corrosion-resistant copper castings of the pump also needs to be considered comprehensively. It is recommended to design the casting geometry and size according to the working conditions and the properties of the metal materials, and also from the casting alloy and casting process characteristics. From the perspective of the rationality of the design, namely the obvious size effect and solidification, shrinkage, stress and other issues, to avoid or reduce the occurrence of defects such as composition segregation, deformation, cracking of copper castings.


In addition, it is necessary to improve the quality of the raw materials used in the casting. If the quality of the material is not enough, the castings will have defects such as pores, pinholes, slag inclusions and sand sticking, which will affect the appearance quality and internal quality of the corrosion-resistant copper castings of the pump. Therefore, the process operation needs to establish reasonable operating procedures, improve the technical level of the workers, and make the process procedures correctly implemented.
