Study of the melting dust of the underroof space of metallurgical furnaces

During the interaction of refractories with the melt-dust of the underroof space of the metallurgical furnaces, structurally complex low-melting formations are developed. They reduce the life of the lining under the conditions of frequent thermal cycling. Based on the study of the deposits on the corundum tubes, the approximate composition of the gaseous and dusty reagents was determined (wt %): iron oxides, a metallic phase, iron-bearing components 60-70, calcium oxide 15-20, magnesium oxide 3-5, and silicon oxide 5-10.
