By improving the casting process, as shown in Fig. 3, the temperature field in the solidification process of the cast ball is changed to eliminate the defects. The improvement scheme is as follows: raising the riser, the diameter is 67.94 mm, the height is 30 mm, and the feeding capacity of the casting is increased […]
Liang 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, […]
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 […]
