| Abstract: | In the blast-furnace shop at OAO Nizhnetagil’skii Metallurgicheskii Kombinat (NTMK), the smelting of low-silica vanadium hot
metal is being introduced. Theoretical and experimental data reveal the influence of the pressure in the furnace’s working
space and coke quality on the reduction of titanium and the formation of refractory titanium compounds. The residence time
of the melt in the hearth depends on its dimensions. |
