Solidification Temperature Field Numerical Simulation of Wear-Resistant Cast Ball Based on the MAGMA (1)
/in Grinding Media BallsLiang Bing—Li Ye Gen (Mechanical and Electrical RepairFactory，Jinduicheng Molybdenum Group Co., Ltd, Huaxian714102, Shaanxi, China) Abstract：The solidification process of the wear-resistant cast baIls made by metal mold was simulated using the software of temperature field numerical simulation. Based on the study of the cast ball solidification process’s temperature distribution law by improving the casting process, […]
Influence of Filling Modes on Blowhole Defects of High Chromium Cast Iron Grinding Ball (2)
/in Grinding Media BallsInfluence of Filling Modes on Blowhole Defects of High Chromium Cast Iron Grinding Ball (1)
/in Grinding Media BallsAbstract: 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 Grinding Media BallsAbstract：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 […]
