The wear behavior of shots impeller pair in shot blast cleaning
This article discussed the compound impact-abrasive wear behavior of shots impeller pair in shot blast cleaning. The shots impeller pairs were fabricated by investment casting processing. The predominance and shortcoming of investment casting for high chromium wear resistance materials used in shot blasting machine were also analyzed. Using investment casting technology, the high-Cr iron casting would be improvement in interal and explicit quality. And, owing to different included angles of shots, the blade show different wear behavior. The ideal included angle of shots is 12°. Increase in the angles leads to decreases of the wear resistance.
