钾、钠、氟的循环富集导致初渣具有最低共熔点,同时析出高熔物相钾霞石等,因而经不起温度波动是包钢高炉下部结瘤的根源。由于软熔带初渣的酸度不够,使过“剩”的碱金属逸向炉身上部,在700～800℃温度范围内是液态凝结在炉料缝隙之间,使其表面进一步渣化而形成非正常液相区,当温度波动时迅速凝固是上部炉料粘结的原因。基于上述原因提出(?)用硅、氟、氯复方洗瘤剂。并指出在原料中的钾、钠、氟未解决前在高炉冶炼中采用酸性初渣操作是当前彻底解决炉瘤唯一正确途径。
The cycle enrichment of potassium, sodium and fluorine leads to the lowest eutectic point of the primary slag and the simultaneous precipitation of high-melting-phase potassium nepheline. Therefore, the temperature fluctuation can not stand the root of nodules in the lower part of Baotou blast furnace. Due to the initial acidity of the reflow zone is not enough, the “left” alkali metal escapes to the upper part of the furnace body and is condensed in the gap between the charge materials at the temperature of 700-800 ° C to further form the residue on the surface of the furnace body. Normal liquid zone, when the temperature fluctuates rapidly solidification is the upper charge bonding reasons. Based on the above reasons (?) Proposed with silicon, fluorine, chlorine compound oncology. And pointed out that in the raw materials of potassium, sodium, fluorine before the blast furnace smelting acid slag operation is the first complete solution to the only correct way furnace.
