The invention provides a fluorine-containing drainage agent, and belongs to the technical field of metallurgical auxiliary materials. The invention relates to a fluorine-containing drainage agent, which comprises the following effective components in percentage by weight: 50 to 70 percent of Al2O3, 8 to 12 percent of SiO2, 1 to 4 percent of F <->, 0.1 to 2 percent of K2O, 0.02 to 2 percent of Na2O, 10 to 25 percent of MgO and 0.2 to 2 percent of C. According to the fluorine-containing drainage agent, the problem that chromium oxide in the drainage agent reacts with aluminum in molten steel in the using process, so that chromium pollution is increased in the molten steel is effectively solved, the requirement for automatic casting is met, the casting rate is high, cleaning is easy, and the used drainage agent cannot cause chromium pollution to the environment. 本发明提供了一种含氟引流剂，属于冶金辅料技术领域。一种含氟引流剂，其有效成分及其重量百分比为：Al2O3为50～70％，SiO2为8～12％，F-为1～4％，K2O为0.1～2％，Na2O为0.02～2％，MgO为10-25％，C为0.2～2％。本发明含氟引流剂，有效减弱使用过程中在引流剂中氧化铬与钢水
