Conclusions
We basically clarified the process of the destruction of refractories in various areas of blast furnaces using ferrugineous fluorine-containing ores and made recommendations with regard to the selection of refractories.
A number of experiments were carried out in the laboratory on the study of the destructive effect of a gas mixture with hydrogen fluoride, fluorine-containing blast furnace slags and calcium fluoride on alumosilicate refractories; we have explained the mechanism of the destruction of refractories in the system of interaction between CaF2 and Al2O3-SiO2.
