·In response to the problem of rich vanadium titanium magnetite VTM resources in China contrasting with low blast furnace utilization a HIsmelt process for smelting VTM is proposed The influence of the process parameters on smelting reduction is analysed under laboratory conditions by simulating smelting reduction The results show that extending the
·Cheng et al restated the negative effect of high titanium dioxide content on smelting and the phase transformation behavior was discussed [28 29] It was proved that that adding proper amount of CaO and B 2 O 3 to VTM pellets could restrain the formation of TiC/Ti C N on the smelting process [30 31]
smelting plant that process magnetite and titanium smelting plant that process magnetite and titanium « mill gold Process Overview The steel plant produces vanadium slag which is used to produce an alloy for Owing to the high titanium content of the magnetite ore Evraz The Ironmaking Process New Zealand Steel The New Zealand Steel plant at Glenbrook is unusual in that the
·is suitable for smelting vanadium titanium magnetite has been proposed reasonably in accordance with the problems of vanadium titanium magnetite in the existing smelting process The process is composed of two parts the pre reduction process of vanadium titanium magnetite in the rotary kiln and the slag iron separation process in the pure
·It is noted that the processing of titanium containing concentrates and ores is difficult they are refractory and difficult to recover In order to process such materials it is necessary to create conditions for the primary solid phase reduction of ferrum the rate of reduction of ferrous oxides must run ahead the rate of formation of the slag phase and smelting
Metals 2022 12 1019 3 of 11 changing the CaO addition ratio to satisfy basicity of which is the suitable basicity for smelting vanadium titanium magnetite in HIsmelt [13]
The vanadium titanium magnetite blast furnace smelting method provided by the invention can effectively improve vanadium yield during vanadium titanium magnetite smelting process simultaneously accelerate the reduction of iron improve the smelting intensity and production of the blast furnace has an important significance in improving
·HIsmelt is well suited for smelting vanadium titanium magnetite due to its flexibility in feedstock selection and tolerance to high viscosity slag compared with the blast furnace In this work the effect of smelting time on the distribution behavior and recovery rates of vanadium and titanium in HIsmelt smelting of vanadium titanium magnetite was investigated
·In recent years the oxygen blast furnace OBF process propelled by the carbon peak and carbon neutrality policies has increasingly garnered attention from researchers emerging as a pivotal technology for achieving carbon neutrality in the steel industry Ariyama et al 2019 Takahashi et al 2015 Ariyama et al 2016 The iron and steel metallurgical sector
·The results showed that the reasonable smelting parameters for vanadium titanium magnetite smelting of the process introduced in the paper were above 1450 °C of smelting temperature above of basicity of slag 30 40 min of smelting time and 20 22% of coal addition Nevertheless the sulfur content of the iron particle was higher than
