Influence of Filling Modes on Blowhole Defects of High Chromium Cast Iron Grinding Ball (1)

/in

Abstract: To solve the problem of the blowhole defects in the center and on the high chromium cast iron grinding ball’s surface, the influence of the two filling modes—one-ball mold and four-ball mold on blowhole defects were analyzed. The result indicated that the four-ball m old’s venting effect with parting—line gating system is better. The impact […]

Study on production process of low-cost new wear-resistant grinding balls(1)

/in

Abstract：The effects of chemical composition and heat treatment on properties of the wear-resistant grinding balls were studied through hardness and impelling strength test, metallographic structure analysis. The study used an orthogonal test instead of a fixed variable method for a shorter experimental cost and time. The experimental results show that the wear-resistant grinding balls show […]
