摘要
对影响离心铸造球墨铸铁套石墨组织的因素进行分析,采用优化成分配比,配入合金元素Mo、Cu;采用二次孕育,加入微量元素Bi;采用水冷与空冷相结合的强制冷却浇注工艺,达到了增加石墨球个数,改善石墨球分布均匀性的目的。
This article has analyzed the factors that affect the graphite structure of the centrifugal nodular cast iron sleeve. By adopting the distribution ratio of optimized composition, adding alloy elements Mo＆Cu and then with secondary inoculation adding microelement Bi; as well as the forced cooling pouring process combined the water cooling and air cooling, the quantity of graphite can be increased, which improved the distribution evenness of the graphite.
