通过烧结中断试验，研究了包钢烧结过程中钾、钠、氟的行为：原矿中的微斜长石，霓石和萤石分别形成了钾霞石、三斜霞石和枪晶石，并存于烧结矿中；同时还发现烧结过程中产生了少量钾、钠、氟的挥发物，并为湿料带所吸附，而在烧结饼上部产生了区域净化现象。因此，为减少钾、钠、氟对高炉冶炼的危害，需要把烧结矿烧好烧透。 Through the sintering interruption test, the behavior of potassium, sodium and fluorine during the sintering process of Baotou Steel was studied. The micro plagioclase, nitrite and fluorite in the ore form kaliane, triclinic nepheline and gunsolite, respectively, Ore. At the same time, it was also found that a small amount of volatiles of potassium, sodium and fluorine were produced in the sintering process and were adsorbed by the wet zone, while the top of the sintered cake produced a regional purification phenomenon. Therefore, in order to reduce the harm of potassium, sodium and fluorine to the blast furnace smelting, it is necessary to burn the sinter well.
