Prior to the Industrial Revolution, the main form of carbon was charcoal. 31 Since the interior of a smelting furnace is a densely packed, lowoxygen environment, the burning charcoal produces mainly carbon monoxide, which rises through the molten ore, stripping away oxygen atoms from the iron oxide. 23 The iron itself would sink to the bottom ...

The composition of a titanium slag from sorel. ... in the slag is high as a result of the addition of more carbon during the reduction of ilmenite, the product decrepitates on cooling owing to the ...
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 ...
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
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.

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 ...
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.
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 ...

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.
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.
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.
electrode moving can not exceed 0,02 mis we failed in tapping the titanium slag produced in this furnace. The titanium slag managed to solidify before the rotation of crucible started. The approach to raw materials smelting by liquid slag results in stabilizing electrical energetic conditions for the process.
The charge structure of highcarbon ferrochrome for blast furnaces at home and abroad does not have a fixed pattern. Each blast furnace is selected based on factors such as the natural resources available to the enterprise, the metallurgical properties and physical and chemical composition of iron ore, and the cost of blast furnace ironmaking.
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.
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 .
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).

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.
