Skills for quality assurance of wind power castings

- Mar 29, 2021-

So what are the other techniques to ensure the quality of wind power castings besides tensile strength?


1. The design process of wind power castings - ductile iron castings requires reasonable solutions when designing the workpieces. In addition to determining the geometry and size of the castings according to the working conditions and metal material properties, the casting alloys Consider the rationality of the design from the perspective of casting process characteristics to avoid various undesirable phenomena in the production process.


2. The casting process of wind power castings also needs to be determined according to the characteristics of the material and production conditions, product structure, size and weight, depending on which method is suitable. 


3. The correct selection of raw materials and quality assurance. In addition to the corresponding pig iron raw materials used in the production of wind power castings, there are also nodulizers, furnace materials, refractory materials, fuels, fluxes, modifiers, foundry sand, and sand bonding. Each of other materials, such as chemicals, coatings, etc., must be carefully selected, and no carelessness is allowed.


4. The ability of operating personnel is also one of the important factors that affect the quality of the castings of Qiufeng Power. In normal times, it is necessary to strengthen the training of production technicians and improve casting.


5. The production management of the entire enterprise ensures that every work process is in place and eliminates all unfavorable factors.
