1. Is the appearance of the steel shot the darker and brighter, the better the quality
The truth: the darker and brighter the appearance of the steel shot indicates that the heat treatment temperature in the production process is too high, which reduces the carbon content in the steel shot during production, so that the hardness of the steel shot becomes lower, and the steel shot is in the process of striking It is easy to deform.
Conclusion: The darker the steel shot, the brighter the steel shot is'not useful'
2. How effective is the recycled steel shot ("return shot") used?
Truth: The back shot is better than the new steel shot, but the source of the back shot is uneven. It is recovered from alloy steel shot, cut steel wire shot and other various steel shots, so the composition is not uniform and the particle size is not uniform. Uniformity, which seriously affects the gloss and roughness of the workpiece after being hit.
