Reduction Behaviors of Iron, Vanadium and Titanium Oxides in Smelting of Vanadium Titanomagnetite Metallized Pellets

Slag-metal Separation and Reduction Behaviors of Vanadium-bearing Titanomagnetite Metallized Pellets

“…In addition, excessive smelting time may lead to the reduction of titanium oxides and formation of TiC in slag, which would decrease the recovery of TiO 2 in slag and deteriorate the kinetics of mass transfer of V 2 O 3 in molten slag. [25][26][27] The carbon contents in metal phase exhibit the first decreasing and then increasing trend with the increase of smelting time. As described above, it is mainly related to the reduction of vanadium oxides during smelting separation of metallized pellets.…”

Advanced converter sludge utilization technologies for the recovery of valuable elements: A review

“…The reduction of iron oxides to metallic iron at the temperature lower than liquidus temperature is called direct reduction, and the obtained pellets are called metallized pellets [35][36][37]. Researches [36,38,39] showed that the use of metallized pellets in the blast furnace could greatly reduce coke consumption and increase productivity. The typical process of metallized pellets is summarized in Fig.…”

Effect of temperature patterns on iron nugget formation in fluxless processing of titanomagnetite

“…In addition, the other problems are the formation of TiC and TiN because the atmosphere in the hearth blast furnace is very reductive and the use of hot blast air in the tuyeres as a source of nitrogen. The TiC and TiN cause the slag to become viscous, which causes a lot of metal to be trapped and enter the slag 6 .…”
