镧系球化剂在球墨铸铁件生产中的应用

摘要

介绍镧系球化剂在使用安全要求较高的球墨铸铁件生产中的应用。生产实践表明：使用镧系球化剂球化处理后，不仅可以提高球墨铸铁件内在质量，如提高球化率，增加石墨球数，消除碎块状石墨，减少缩松倾向等，而且可以降低生产成本，具有显著的经济效益。%This paper mainly introduced the application of La based FSM (nodulizer) in safety-critical components ductile iron castings. The production practice proved: through using La based FSM(nodulizer), it can improve the inner quality of the castings, such as high the nodularity, increase the nodule counts, removing the chunky graphite, reduce the tendency of shrinkage, and reduce the production cost, it have obvious economic beneift.
