Mar 01, 2016· Abstract The carbothermic reduction experiments were carried out for titanium-bearing 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 X-ray diffraction (XRD) and scanning electron microscope (SEM). The XRD .

Activated carbon, gold dust sands, electrolysis mud, gold and silver powder, tin ash tin slag etc.

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 10-pound slag charges were reacted with 14.3 pounds of carbon and 8.6 pounds of lime at 4,350° F for 3 hours.

The invention relates to a method for producing titanium oxide-containing slag and pig iron from ilmenite. The method is characterized in that it comprises the steps: a) pre-reducing 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 pre-reduced ilmenite; and c ...

Uses of titanium and its extraction from its ore, there is a

Li et al. studied the carbonization (nitrogenation) for titanium-bearing 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 ...

Carbon for titanium slag furnace. Slag refractory interactions during ilmenite smelting the interaction of four types of commonly used refractories ie, burned magnesite brick, magnesia carbon brick, corundum castable, and sic castable with slag formed in the smelting of titanium wt t.

Jan 07, 2013· Titanium is one of the most valuable elements found in blast furnace slag, with a concentration of approximate 2.7%. 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, solid-to-liquid ratio, and ultrasonic wave time were used to determine the .

For a furnace with basic refractories, which includes most carbon steel-producing 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.

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.

The analysis of typical slag obtained by Electro Slag Crucible Melting process and other slag compositions reported by other investigators (Sahoo 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.

Contracted by Yunnan XinLi, we supplied the core equipment of a DC furnace for titanium oxide slag production. The completion of this plant clearly shows that SMS group has supplied the major equipment for almost all DC-based titanium oxide slag furnaces.

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. 1 fig.

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

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.

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).

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 ...

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 non-uniform 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.

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.

Titanium is one of the most valuable elements found in blast furnace slag, with a concentration of approximate 2.7%. Because of the low level of titanium in slag, the best method of extraction is ...

The interaction of four types of commonly used refractories (i.e., 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 studied.Erosion of refractories by titanium slag was calculated using the FactSage software program.
