There were two controlling factors, which should be kept balance of raw input and energy during titanium slag smelting in closed high power direct current electric arc furnace, DC furnace for short. The first factor contains compositions and ratio of input raw materials. Compositions of the raw could influence the progress and technical indicators of DC furnace smelting, and on the meanwhile ...
Recent experiment in our laboratory demonstrates that an increase in slag ing with carbon injection rate is limited by slag volume. The current work has identified a relationship between height, carbon injection rate and slag volumes, which predicts the critical injection rate above which ing become inefficient. The
As a result, the blast furnace titanium slag in CaTiO3 primary phase field contains less than 25% (mass fraction) TiO2, where the titanium resource cannot be recovered economically due to its low TiO2 content. Therefore, many other methods [5âˆ''12] are developed to achieve the comprehensive utilization of vanadium titanomagnetite ore.
A method for the recovery of valuable materials from titanium grinding swarf is provided comprising the steps of sieving the accumulated titanium grinding swarf to remove unwanted coarse trash and grinding wheel fragments, pelletizing, and smelting in an electric arc furnace to produce ferrotitanium and/or high titanium slag.
Jan 07, 2013· Titanium is one of the most valuable elements found in blast furnace slag, with a concentration of approximate %. Because of the low level of titanium in slag, the best method of extraction is hydrometallurgy. In this study, parameters such as slag particle size, temperature, concentration of acid, solidtoliquid ratio, and ultrasonic wave time were used to determine the recovery of titanium.
Prereduction and DC openarc smelting of carbonbased ilmenite pellets K. Bisaka, I. Thobadi, and X. Goso Pyrometallurgy Division, Mintek The smelting of ilmenite to produce valuable titania slag and pig iron is an energyintensive process. At process temperatures of about 1700°C, roughly 1 MWh of electricity per ton of ilmenite feed is consumed.

These tests demonstrated that titanium slag with a high lime content can be converted to TiC with results similar to those achieved with perovskite. Best conversions of titanium slag to carbide (95 percent) were achieved when 10pound slag charges were reacted with pounds of carbon and pounds of lime at 4,350° F for 3 hours.

For a furnace with basic refractories, which includes most carbon steelproducing furnaces, the usual slag formers are calcium oxide (CaO, in the form of burnt lime) and magnesium oxide (MgO, in the form of dolomite and magnesite). These slag formers are either charged with the scrap, or blown into the furnace during meltdown.
The invention relates to ferrous metallurgy and can be used in Ferroalloy industry, specifically in the production of low carbon ferrochrome. Various methods for the production of lowcarbon (refined) of ferrochrome in electric furnaces or spacegreat, allowing to obtain a low content of carbon in it, but they are inefficient and typically require the use of high quality materials.
Large quantities of CO 2 and blast furnace slag are discharged in the iron and steel industry. Mineral carbonation of blast furnace slag can offer substantial CO 2 emission reduction and comprehensive utilization of the solid waste. This paper describes a novel route for indirect mineral carbonation of titaniumbearing blast furnace (TBBF) slag, in which the TBBF slag is roasted with ...
duction of the titaniarich slag is further acidleached under a highpressure and moderatetemperature hydrometallurgical process to yield an upgraded titania slag with mass percent TiO 2, which is used in the chloride process. After describing in detail the beneficiation, chemistry, and mineralogy of the hemoilmenite ore, this
by allowing increased carbon injection into the slag of electric arc furnace the (PeO) content in slag is decreased, and the quality of melting steel is improved [Ozawa et al 1986, Ameling et al 1986]. The rate of reaction between (FeO) in slag and carbon in slag plays an
Dec 27, 2018· The base blast furnace slag composition in SiO2Al2O3CaOMgO system is fixed at CaO/SiO2=, 16 wt% Al2O3 and 8 wt% MgO. ... For studying the carbon thermal reduction rules of titanium in hot ...
* The majority of components in Granulated Blast Furnace Slag are various glassy Metallic Silicates (Iron, Calcium, Magnesium, Aluminum, and Titanium Silicates), including: Dicalcium Silicate (Ca2SiO4), Merwinite (Ca3MgSi2O8), and Gehlenite (Ca2Al2SiO7) .
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
