用稀土镁合金代替金属镁(纯镁)作球化剂)是当前球墨铸铁生产中的重大变革。随着稀土镁合金的广泛应用,其处理工艺也越来越被人们注意。我们原采用“包底冲入法”,因有大量镁汽化形成“镁烟”逸出,吸收率甚低,尤其是冬季“镁烟”逸出现象更为严重,不仅影响质量的稳定,而且危害工人身体健康。 Rare earth magnesium alloy instead of metal magnesium (pure magnesium) as a nodulizer) is a major change in the production of ductile iron. With the wide application of rare earth magnesium alloy, its treatment process is also more and more people’s attention. We originally used the “bottom-infiltration method”, due to a large number of magnesium vaporized to form “magnesium smoke” escape, the absorption rate is very low, especially in winter, “magnesium smoke” escape phenomenon is more serious, not only affect the quality and stability, Endanger the health of workers.
