Casting Production Technology of Wear-resistant Steel Hollow Ball
The wear-resistant steel hollow ball is a spherical part that is widely used in many industrial and agricultural applications, such as ball valves, pumps, mixer, and conveyor systems. It can improve the service life of the device and parts, reduce maintenance costs, improve production efficiency, and enhance the production safety. Because of the wide range of applications and the special requirements for wear resistance, the production of wear-resistant steel hollow ball must use special processes and technology, and the key process of steel hollow ball production is casting. Therefore, the production technology of wear-resistant steel hollow ball needs to be inspected and studied in depth.
Casting process of wear-resistant steel hollow ball
The production process of wear-resistant steel hollow ball is generally divided into three parts: smelting → forging → casting, and the casting process of wear-resistant steel hollow ball is shown in Fig.1.
(1) The raw materials are smelted in the furnace and the smelting materials are closely inspected and monitored. The composition of the smelting materials must be blended and adjusted according to the requirements of the wear-resistant steel;
(2) After cooling, the smelted material will be transferred to the forging machine for forging process. The forging adopts the pneumatic forging machine, which can form the tube blank with the required section shape and size;
(3) The tube blank is put into the split type silica sol investment casting production line, and the special process of silica sol investment casting is adopted. The inner and outer surfaces of the cylinder wall are coated with a layer of refractory coat to prevent steel from adhering to sand in the casting process;
(4) Finally, the wear-resistant alloy steel pipe is placed in the converter, heated by gas and electric heating, and heated to a certain temperature, then the wear-resistant alloy steel pipe will be formed into a finished hollow ball after strong air pressure.
Conclusion
The casting production technology of wear-resistant steel hollow balls is an important part in the production process of steel hollow balls, and the correct process control and material selection are conducive to improving the wear resistance of the products. This article introduces the production technology of wear-resistant steel hollow balls and explains the casting process in detail, which provides a reference for the production and application of wear-resistant steel hollow balls with adequate wear resistance and high performance.
