Casting workpiece: Large castings of the same weight will consume more steel shots than small castings. This is easy to understand, because the surface area of castings with the same weight is relatively large. The same casting is related to the hardness of its surface. The higher the hardness, the greater the consumption of steel shot; the lower the hardness, the less consumption. According to statistics, one ton of steel shot can clean about one hundred tons of castings. If the casting structure is complex, resulting in waste of steel shots, these are not included in the consumption of steel shots.
Shaped steel and molds: Because everyone’s workpieces have different models and different hardness, the same consumption rate varies greatly. It must be that the higher the hardness of the workpiece, the greater the loss. Basically, 1 ton of cast steel shot can handle about 130 tons. steel.
The reason for the sudden increase in the consumption of steel shot, the editor of An Landi Steel Shot summarized the following points:
1. Adjust the angle of the shot blaster of the shot blasting machine; make the steel shot and steel grit effectively act on the workpiece while preventing the useful steel shot and steel grit from being discharged in the shot separator or dust collector.
2. Take back the steel shot and steel sand leaked outside the shot blasting machine in time.
3. Prevent the steel shot and steel grit from being taken away with the workpiece.
4. Frequently check whether the shot blasting machine is damaged or not.
5. Reasonably add settling tanks.
6. Replace the sealing rubber plate of the shot blasting machine in time.
7. Do a good job of recycling and screening the steel shot and steel sand of the shot blasting machine.
