包芯线喂线处理生产球墨铸铁是一种新的球铁生产工艺。本文系统地介绍了喂线球化处理在国内外的发展与应用现状，详细地讨论了芯线结构、芯线含镁量、球化剂种类、喂线工艺等对镁吸收率、脱硫率、温度损失、球化质量、环境污染及处理成本的影响。 Cored wire feeding line processing production of ductile iron is a new ductile iron production process. This paper systematically introduced the development and application status of feeding line balling treatment both at home and abroad. The effects of the core structure, the magnesium content of the core, the type of nodulizer and the feeding technology on the magnesium absorption rate, desulfurization rate, Temperature loss, balling quality, environmental pollution and disposal costs.
