Titania slag, which comes from ilmenite, contains 85 per cent titanium dioxide. Granulation of titania slag has been identified as a potential viable alternative to the conventional block route. Both wet and dry granulation of titania slag has been investigated.
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.
Materials melted in the carbonlined furnace generally provided higher slag quality than those processed in the magnesitelined furnace, particularly with respect to the lime and magnesia content. Accordingly, most tests were conducted in a carbonlined furnace shell to provide optimum slag quality.

236 titanium slag products are offered for sale by suppliers on, of which titanium scrap accounts for 9%, other titanium accounts for 6%, and industrial furnace accounts for 2%. A wide variety of titanium slag options are available to you, such as fines (powder), lump.
The analysis of typical slag obtained by Electro Slag Crucible Melting process and other slag compositions reported by other investigators (Soo et al., 1999, Swinden and Jones, 1978) are given in Table 3. The chemical analysis suggests that the prepared slag would be suitable for the sulphate process of titanium dioxide pigment manufacture.
The interaction of four types of commonly used refractories (, burned magnesite brick, magnesia carbon brick, corundum castable, and SiC castable) with slag formed in the smelting of titanium (wt. [TiO 2] = 80%) in an electric furnace at the Panzhihuan Iron and Steel plant was of refractories by titanium slag was calculated using the FactSage software program.
Submerged Arc Furnaces industrial utilization of electrical energy started with the development of the dynamo machine by Werner von Siemens. Electric arc furnaces have been used for many years both for the melting of scrap iron (open arc furnaces) and for reduction processes (submerged arc furnaces).
Mar 01, 2016· Abstract The carbothermic reduction experiments were carried out for titaniumbearing blast furnace slag in Panzhihua Iron and Steel Company in argon atmosphere at high temperatures. The effects of reduction temperature, isothermal treatment time and carbon content on the formation of TiC were studied by Xray diffraction (XRD) and scanning electron microscope (SEM). The XRD .
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.
A KINETIC STUDY OF CARBON INJECTION INTO ELECTRIC ARC FURNACE SLAGS 399 Introduction Slag ing has been extensively studied because of its importance in many pyrometallurgical processes1– the
furnace. The transport phenomena and physical status in the hearth of an iron making blast furnace are very complicated and difficult to monitor and characterise. The nonuniform flow, heat transfer, and carbon dissolution from the refractory and the coke bed (dead man) cause large differences in thermal conditions and hot metal composition.
Briefly, even though many previous works [21âˆ''25] about the blast furnace titanium slag were done, the suitable composition of higher titanium slag with MgTi2O5 as the main phase for smelting vanadium titanomagnetite by the DRâˆ''EF process is not very clear.
Sep 18, 2019· Just below the middle of the furnace, the temperature is high enough to melt both the iron and the slag. They collect in layers at the bottom of the furnace; the less dense slag floats on the iron and protects it from oxidation. Several times a day, the slag and molten iron are withdrawn from the furnace.

Li et al. studied the carbonization (nitrogenation) for titaniumbearing blast furnace slag by plasma furnace. With the sample of slag being held in the plasma furnace at 1,973 K for 1 h, 92% TiO 2 in the slag can be transformed into Ti(C,N) and the diameter of Ti(C,N) crystalline is more than 20 μm. Although many works have been done, the ...

and Mehdilo, 2004) and then converted to titanium slag by the carbothermic reduction smelting process in a DC electric arc furnace (Mehdilo and Irannajad 2006; Mehdilo et al., 2006; Irannajad and Montajam, 2005). In the present study, the iron removing from the produced titanium slag was investigated by sulfuric and hydrochloric acid
The invention relates to a method for producing titanium oxidecontaining slag and pig iron from ilmenite. The method is characterized in that it comprises the steps: a) prereducing ilmenite in the presence of reductant in a prereduction reactor to metallize at least part of iron in the ilmenite; b) optionally removing unreacted reductant and gangue from the prereduced ilmenite; and c ...
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 ...
