Abstract: High Chromium cast iron is a kind of excellent wear-resistant material; it not only has good wear resistance but also has a specific camber and toughness; electric Power and other industries have been widely used and achieved significant economic benefits.
Heat treatment process: It is difficult to quench the wear resistant cast ball, mainly because the quenching requires martensite, and the cooling rate must be higher than the critical cooling rate (VK). During quenching, how can martensite be obtained and the effect of stress reduced? This is a major problem in the quenching process. To […]
Dang Jun-peng (Aluminium corporation of China zhongzhou branch, Jiaozuo 454174, China) Abstract： High chromium cast iron is considered to be the best of the anti-wear properties and has a good toughness of the material, So in this cast iron abroad used widely. For years the ball from high chromium cast in the research and production […]
The die core parameters and a sprue of the optimized process are shown in figures 8 and 9. The variation of the parameters of the ball casting’s specific position and the yield rate of the ball casting before and after the scheme is shown in Table 1. It can be seen from Table 1 that […]
