Description
It is analysed some titaniferous magnetite deposits of Russia.
The results of laboratory, industrial and calculation (by means of mathematical models) researches of physical, chemical and thermophysical processes at oxidizing roasting (agglomeration) of the titaniferous raw materials are considered. The rating of influence of metallurgical properties (reducibility, durability, softening and melting temperatures of agglomerated ores) on processes heat and mass exchange at the reduction in blast furnace is executed. Titan-bearing ores with the various TiO2 content are investigated.
It is shown that the main reserve of coke consumption decrease and improvement of the technical and economic indicators of blast furnace smelting is improvement of quality of iron ore raw materials.
