In the production process of stainless steel pump castings, the metal liquid metal formation techniques are more. The size needs to accurately be controlled. Stainless steel pump casting has excellent mechanical and physical properties, it can have comprehensive performance combined with various strength, hardness and toughness. It also has one or more special properties, such as wear resistance, high temperature and low temperature, corrosion resistance.
The size and weight of the stainless steel pump castings are wide. The lightest weight can reach a few grams, and the heaviest weight can reach 400 tons. The thickest thickness can be more than 1 meter and the thinnest thickness is only 0. 5mm. The length can be from a few millimeters to a few meters, and can meet the use requirements of different industrial departments.
The application of stainless steel pump castings
Such products have been widely used in the machinery, electronics and hardware industries. Its use range is constantly expanding. It is widely used in machine tools, watercraft, aerospace, cars, locomotives, electronics and other industries.
The casting process of stainless steel pump castings
In the casting process of stainless steel pump castings, it is necessary to follow the principle of discharging at high temperature and pouring at low temperature, so as to improve the discharging temperature of metal liquid, the complete melting of inclusions, slag flotation, easy slag cleaning and degassing, and reduce the slag and pore defects of the machine tool.
Using lower pouring temperature is beneficial to reduce the gas solubility, liquid shrinkage and baking of high temperature metal liquid to the cavity surface, so as to avoid defects such as air hole, sand sticking and shrinkage cavity. Therefore, under the premise of ensuring full mold cavity, the lower pouring temperature is adopted as far as possible. The operation process of pouring molten metal from the ladle into the cast is called pouring.
