无氟连铸保护渣的研究现状及展望

Research Status and Prospect of Fluoride-free Mold Fluxes

传统保护渣中加入一定量的氟化物对其关键性能起着特殊的控制作用,但其中的氟却对现场工作人员、设备及环境带来巨大危害,因此开发绿色环保无氟连铸保护渣意义重大。本文阐述了氟在保护渣中的作用及其危害,总结归纳了目前国内外无氟保护渣的研究进展,剖析了现阶段存在的主要问题,指出从微结构角度系统研究保护渣冶金性能,完善保护渣制定原则理论依据,是无氟连铸保护渣工业化过程中亟待解决的关键问题。

By adding a certain amount of fluoride in the traditional mold flux can control its key performance, but the fluoride carried has great harm on staff, equipment and environment. It has important significant to develop the fluoride-free mold fluxes. The effects and harm of fluoride wwer described in detail, the current research progress of fluoride-free mold fluxes was summarized, and the main questions were analyzed. The key problems of fluoride-free fluxes for continuous casting in industrialization process is to study on metallurgical properties deeply from the structure.
