How can the service life of steel shots be extended?

　　1. Choose steel shots of appropriate quality

　　When purchasing, select steel shots with good hardness, toughness, and wear resistance. For example, using alloy steel shots that have undergone special heat treatment processes.

　　2. Optimize shot peening process parameters:

　　Accurately control the injection pressure, speed, and angle to avoid excessive wear of the steel shot caused by excessive pressure and speed. For example, according to the material and shape of the workpiece, the injection pressure can be appropriately reduced.

　　3. Improve the working environment:

　　Keep the workplace dry and ventilated to reduce the erosion of steel shots by moisture and corrosive gases. If possible, install air purification and dehumidification equipment.

　　4. Reasonable screening and grading of steel shots:

　　Regularly screen and grade used steel shots, remove severely worn and broken steel shots, and only retain those in good condition for continued use.

　　5. Correct steel shot storage:

　　When storing steel shots, they should be protected from moisture, contamination, and mixing. Store in a well sealed container.

　　6. Regular maintenance of shot blasting equipment:

　　Ensure the normal operation of equipment components such as spray guns and pipelines to prevent abnormal wear of steel balls caused by equipment failures. For example, timely replacement of worn spray gun nozzles.

　　7. Control the number of cycles of the steel shot:

　　Set a reasonable upper limit for the cyclic use of steel shots, and replace them with new ones promptly after exceeding the limit.

　　For example, a car parts manufacturing company regularly screens and grades steel shot, removes severely worn steel shot, and selects high-quality alloy steel shot. At the same time, it optimizes the shot blasting process parameters and adjusts the spray pressure from the original high value to the appropriate range, which extends the service life of the steel shot by 30% and reduces production costs.

　　For example, in a steel structure processing plant, by improving the working environment, installing ventilation and dehumidification equipment, the impact of moisture on the steel shot was reduced, and coupled with reasonable control of the number of steel shot cycles, the service life of the steel shot was significantly improved.
