The influencing factors of shot blasting strength of shot blasting machine

The shot blasting strength of the shot blasting machine is not fixed, it often changes due to some aspects. However, when we use the shot blasting machine, we generally want to know what factors caused the shot blasting machine to change the projectile intensity. If you are interested, you can take a look at the following:

We all know that the strength of the shot blasting machine projected steel shot is strong or weak, so what factors will affect the projecting strength?

1. The speed of shot blasting

When the shot blasting speed of the shot blasting machine increases, the strength will also increase, but the faster the speed, the damage rate of the shot blasting will increase accordingly.

2. The size of abrasive

The larger the steel shot projected by the shot blasting machine, the greater the impact and the greater the strength, but the coverage rate of shot blasting will be lower. Therefore, we need to use smaller steel shots as much as possible while ensuring the strength of shot blasting. In addition, the size of the shot peening will be restricted due to the shape of the part. If there are grooves on the part, the diameter of the shot blasting should be smaller than half of the inner radius of the groove. Half of the shot blasting is between 6 and 50 mesh.

3. The hardness of shot blasting

If the hardness of shot blasting is higher than the hardness of the parts, then changing its hardness value will not affect the strength. If the hardness of shot blasting is lower than the hardness of the part, then as the hardness value decreases, the strength of shot blasting will also decrease.

4. The amount of broken shot blasting

After the shot blasting is broken, the kinetic energy will decrease, so the more the shot blasting is broken, the more the projectile strength will decrease. Moreover, because of the irregular shape of the broken steel shots, the appearance of the parts will be damaged. Therefore, the broken shots must be cleaned frequently to ensure that the intact rate of shot blasting is above 80%.

5. Radiation point of view

When the shot blasting jet and the surface to be sprayed remain straight, the shot blasting intensity is the highest, so it is recommended to perform shot blasting intermittently in such a state. If it is constrained by the shape of the part and a smaller shot blasting is required, the shot speed needs to be increased a bit.

The five aspects introduced above are the analysis of factors that affect the shot strength of the shot blasting system. The operators of the shot blasting machine must be trained on the job before they can operate so that they can deal with any emergencies in time.

The projection strength of the shot blasting machine will generally change due to the above factors. You can pay more attention to these factors in the subsequent use.
