titanium concentration in hot metal by adding a significant amount of titanium raw material and controlling the furnace heat to a little higher level before shutdown with intensifying hearth cooling. 1. INTRODUCTION The main wear mechanisms for the lining of the hearth are abrasion caused by flowing hot metal/slag and corro
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.
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.

high titanium slag plant Grinding Mill China. carbon for titanium slag furnace high titanium slag plant relatively high current densities are used carbon anodes are not consumed . get more info. carbon for titanium slag furnace apollociclinic. extraction of titanium chemguide. Uses of titanium and its extraction from its ore, there is a
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
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
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
* 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) .
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.
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 ...
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.

After describing in detail the beneficiation, chemistry, and mineralogy of the hemoilmenite ore, this
offers 239 titanium slag products. About 9% of these are other titanium, 7% are titanium scrap, and 2% are industrial furnace. A wide variety of titanium slag options are available to you, such as is powder, not powder.
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.
Nov 24, 2008· The arc is about 3000°Celcius and scrap steel is melted in three charges to get around 40 tonnes of steel to be further processed in the ladle furnace. The rods are from carbon and the arc ...
A method of preparing a prereduced ilmenite ore for smelting, wherein metal oxides contained in the ore are selectively reduced in solidstate reactions over titanium oxide, the method including the step of prereducing carbonbased pellets of the ore.
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
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 furnace was lined with carbon brick and a rammed carbon hearth rather than with a normal refractory material, such as magnesite, to prevent excessive contamination of the molten slag by refractory oxides. Carbon was considered a less objectionable impurity than refractory oxides in titanium slag. Procedure and Results
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.
