Abstract:
Nowadays, the raw sources of the Urals ferrous metallurgy are largely titanium iron ore deposits. The same deposits including ferrovanadium and ilmenite ores, deposits of Siberia and the Far East of Russia and deposits of the Uzbekistan Republic will be the most important iron, titanium and vanadium sources on the near-term and far outlook.The characteristics of ores and concentrates of the Gusevogorsky and actually Kachkanarsky deposits of the Sverdlovsk region, Kopansky and Medvedevsky deposits of the Chelyabinsk region, Kuranakhsky deposit of the Far East, Tebinbulaksky deposit of the Republic of Uzbekistan etc, are presented in the paper. The technological basis of processing of different ferrovanadium and ilmenite ores with receiving iron, steel, pigmentary titanium dioxide and vanadium compound was discussed.
The method of evaluation on the influence of iron ore materials and coke quality on the engineering-and-economic performance of blast furnace smelting was described. The method consists in the following: lab investigations with definition of metallurgical characteristics of iron ore materials and coke; analytic research of influence the characteristics on the blast furnace smelting efficiency by using mathematical models; pilot and industrial testing. The method is added by the predicted mathematical model for complex investigation of "hot" properties of coke, which is based on the data of initial ore quality for coking.
The mathematical models of blast furnace process entered in the method are presented in the paper. These mathematical models consist of the logic-statistic balance model, balance equilibrium model, complex of two-dimensional models of gas dynamics, reduction, heat exchange, cohesive zone.
The general principles of processing titanium ores and concentrates were formulated.
