Qingdao steel shot undergoes secondary quenching with minimal dust and good cleaning effect

Description :

　　During the production process of steel shot and steel sand, whether produced in a medium frequency furnace or an electric furnace, the steel must be quenched and tempered according to requirements, and alloy elements such as silicon and manganese must be added according to technical specifications. However, without deoxidation in the molten steel, it can also cause high porosity in the finished steel shot. If melted in a medium frequency electric furnace, aluminum can be added to the molten steel to reduce the porosity of the steel shot. In addition, the reason for the hollow shells of steel balls produced by medium frequency electric furnaces is often due to insufficient temperature, which can be controlled.

　　1、 What is the hollow ratio of national standard steel shot? How to define granularity size? How should the cleaning speed be?

　　Anlandi's national standard steel balls are strictly in accordance with the standards of the Ministry of Metallurgy of China, and are built into an export-oriented brand based on the ISO9000 certification system. Steel shot is irregular circular or approximately circular, and the particle size distribution is also in accordance with metallurgical standards. For example, not all steel shot diameters are 1.0mm for a 1.0 cast steel shot. It may include 0.8-1.2 shot diameters, which are selected in a certain proportion to improve the service life of the steel shot and the cleaning speed of the workpiece. In addition, steel shot is a type of casting product, and casting defects such as hollow and irregular shapes are unavoidable. However, Anlandi's super standard steel shot controls hollow and irregular shapes below 5%. Regarding the cleaning speed, it is directly related to the choice of steel shot model, which plays a decisive role, and the standardized operation of the shot blasting machine (such as adjusting the throwing angle, etc.).

　　2、 Is the usage of steel balls relatively increased compared to before?

　　Has the recent production volume been unstable and increased compared to before

　　2. Have the angle of shot blasting and the air volume of the dust collector been adjusted during the ejection process

　　3. During the use of the shot blasting machine, is the ejection speed adjusted

　　4. The degree of corrosion and sand adhesion of the workpiece

　　5. Differences in hardness, technical requirements, and processing levels of workpieces

　　3、 How much does the high particle size and hollow shell rate of steel shot affect its lifespan?

　　1. The steel shot particles are too small, and the air volume for dust removal is relatively large. At this time, it is necessary to adjust the air damper to reduce the air volume, or to make a dust collector at the dust removal duct, which will use the centrifugal principle to naturally separate the steel shot and dust again.

　　2. There are many steel shot and steel sand shells.

　　3. It is possible that the filter is torn, such as holes in the cloth bag or damage to the filter cartridge, which can cause the steel shot to be directly sucked away by the fan, resulting in waste. Therefore, users of shot blasting machines must regularly maintain and upkeep the machines and dust collectors. Only then can unnecessary losses be reduced.
