Appropriate titanium slag composition during smelting of ...

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 [5−12] are developed to achieve the comprehensive utilization of vanadium titanomagnetite ore.

Chlorination of Titanium Carbide

The slag process used by QIT consists of reduction smelting ilmenite-coal mixtures in an electric arc furnace to separate about 85 pct of the iron as byproduct pig iron and to produce titanium slag containing about 72 wt-pct TiO2, 13 wt-pct FeO, and other oxide impurities.

Control of carbon balance in a silicon smelting furnace ...

Carbon balance of the process is assessed by measuring the amount of carbon monoxide evolved in offgas exiting the furnace. A ratio of the amount of carbon monoxide evolved and the amount of silicon dioxide added to the furnace is determined.

Balance of Raw Input and Energy of Titanium Slag Smelting ...

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 ...

Electric arc furnace - Wikipedia

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.

Chemistry and Mineralogy of Titanium-rich Slags

At the high temperature existing in the furnace, iron forms dense liquid droplets (q ¼ 6800kg m 3) that sink by gravity settling to the bottom of the furnace, forming a pool of a mol- ten iron-carbon alloy. While a thick layer of titania-rich slag floats due to its lower density above the molten iron bath.

1995 The forming of foaming slag in electric arc furnace ...

Besides the above, foaming slag is also able to increase furnace yield, because. 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].

Titanium Slag, Titanium Slag Suppliers and Manufacturers ...

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. MENU

Carbon Injection into Electric Arc Furnace Slags

In the EAF process, carbon, in the form of coke or coal, is injected into molten slag in the late stages of scrap melting. This carbon reacts with iron oxide in the slag, creating gas, which causes slag foaming.

A novel process for preparation of titanium dioxide from ...

A novel process to prepare titanium dioxide from Ti-bearing electric furnace slag by NH 4 HF 2-HF leaching and hydrolyzing process has been developed.In this present study, the effects of [NH 4 +]/[F] mXolar ratio, leaching temperature, [F] concentration, liquid/solid mass ratio, leaching time on the Ti extraction, and the phase transformations have been investigated to reveal the leaching ...

A kinetic study of carbon injection into electric arc ...

carbon is under mixed control by the slag gas and the gas carbon reactions. The relative importance of each step depends mainly on the v-ratio of slags. A relative reactivity parameter χ has been defined and it is found to be important to carbon-slag reaction kinetics and slag foaming. Key words: carbon-slag reaction, kinetics, slag foaming.
