During the smelting of an iron ore containing high fluoride content in a small blast furnace, the hearth refractories were severely corroded. This can be ascribed to the action of very fluid fluoride-containing slags.Moreover, the products of corrosion reactions also have low viscosity which easily flow away from the working face, and leave a new surface fresh for further attack.The stack lining with the same 45%-Al_2O_3 blast furnace brick was, however, in fairly good condition. The chemical analyses of the inner surface of the brick samples show a high percentage of alkali-,alkaline earth-and fluoride-ion contents. But as the amount of melt formed at the temperatures on these zones is comparatively little, that corrosion is not severe.Minerals identified at the stack lining surface consist of: fluorite, fluoro-biotite, kaliophilitenephelite, leucite, cuspidine and spinels etc. This is the first time that mica minerals have ever been identified in blast furnace linings. It is thought that the formation of fluoro-biotite has fixed a part of the F~-, K~+ or Ca~(2+)-ions, which would otherwise go into the melt. Thus its formation actually exerts some protective action against the corrosion of the stack lining.The higher temperatures prevailing in the bosh region in contrast to the stack caused the formation of a much larger amount of fluoride-containing melt, which is probably responsible for the remarkable degree of Corrosion on the bosh refractories.High temperature experiments carried out in the laboratory on the reactions betwccn CaF_2 and 45%-Al_2O_3 brick powder in closed graphite crucibles throw light to explain the process of corrosion of the furnace lining. Hexagonal anorthite was identified in all of these experimtnts, which has identical optical properties and X-ray diffraction patterns with those of hexagonal anorthite synthesized in our laboratory. It is also interesting to note that these hexagonal anorthites change over to normal triclinic modification under heat treatment at 1000℃ for a period of 24 hours.As a result of this and other previous studies in this laboratory, the appropriate selection of refractory materials for the lining of blast furnaces, smelting iron (?)e containing high fluoride content, is recommended.

在某地高氟含量铁矿石的冶炼过程中,炉缸粘土质高炉砖砖视遭到了极其严重的破坏作用。主要侵蚀介质是含氟炉渣,侵蚀产物容易从砖面流失,因而加速了耐火材料的溶解。在炉身部位发现的矿物是:氟化钙、含氟黑云母、钾和钠的铝矽酸盐、枪晶石及尖晶石等。虽然在砖面附着物中包含着相当数量的氟、硷金属及硷土金属的化合物,但是由于温度较低,只有少量熔体出现,砖衬的损毁情况,并不严重。在高炉砖衬中发现云母矿物,还是第一次。在炉身部位的温度条件下,含氟黑云母具有固定F~-,K~+成Ca~(+2)的能力,对砖机起了保护作用。由于炉腹部位的温度较高,较大量含氟熔体出现,侵蚀就相当显著了。 CaF_2—45%Al_2O_3高炉砖的化学反应实验,可以帮助了解高炉砖视的损毁过程。反应产物中发现有六方钙长石,与实验室合成的六方钙长石具有一致的光学性质和X—射线粉末衍射图型。经过1000℃,24小时热处理后,这种六方钙长石会转变成为三斜晶系变体。 根据两个高炉砖衬的化学-矿物学研究及实验室中辅助研究的结果,对于冶炼高氟含量矿石的高炉砖衬的选择提出了建议。

CaO-Al_2O_3-CaO·SiO_2-CaF_2,1,5 1,8~~

我们研究了用不同品位的含氟铁矿石和不同配料所得高炉炉渣的矿物粗成。组成炉渣的结晶物相主要是黄长石固溶体、枪晶石、螢石、乙型正矽酸钙、矽钙石、褐硫钙石及含稀土矿物,另外还有玻璃质。这种炉渣是一种新的类型,它和任何别处研究过的高炉渣的岩石性质都不相同。这种炉渣的结晶过程基本上可以在CaO-Al_2O_3-CaO·SiO_2·CaF_2四元系中来研究,无须牵涉到更为复杂的多元系。 含氟炉渣对于高炉炉衬耐火材料的腐蚀性能是在生产上极关重要的一个问题。从工艺岩石研究结果得到炉渣碱度有一临界值。碱度在此值之上时,炉渣不易腐蚀炉衬,而在此值之下时炉渣严重地腐蚀炉衬。此临界值为一稍高于1.5的数值。冶炼试验结果此数值为1.8。理论数值与经验数值相当好地吻合。 通过炉渣的工艺岩石学研究,我们提出来关于炉渣综合利用的初步意见。

The wetting and chemical action of molten calcium fluoride and five fluoridecontaining slags with various basicity (1.5~3.2) and fluoride content (10~24% F) on carbon refractories at 1400℃ was studied. The results indicated that corrosion is negligible. Carbon blocks may therefore be highly recommended for the hearth lining of blast furnace for the smelting of fluoride-containing iron ore.

研究了氟化钙及不同硷度(1.5~3.2)、氖含量(10~24%F)的五种含氟高炉渣对于炭素耐火材料的化学、润湿作用(1400℃)。实验结果表明,其侵蚀程度十分轻微,故炭砖应可满意地用作冶炼含氟铁矿石高炉的炉缸砖衬。
