- vayaadya slag which is not suitable for the manufacture of light metal vanadium, steel, alloys.
- the resulting vanadium slag was produced in bulk: vanadium oxide -27.8 oxide of oxide - 17.3 iron oxide -22.4 oxide of aluminum * 3.5 oxide of calcium-0.5 carbon oxide - 3.5 magnesium oxide - 0.3 impurities - other
- vanadium cast iron is not available; vanadium slurry is removed;
- Advantages of this benefit from the Canada 20 slag are that the combination of alkali and carbon oxides results in an improvement in the rate of improvement.
- the average size of the vanadium slag is increasing, which is the size of the largest, vanadium-containing slag.
- Another effect of 25 seconds of the influence of these components is the generation of a pure spinelide microstructure.

- the Canada slag composition as indicated above, is obtained from vanadium cast iron by its oxidation by a gas oxidizing agent. We found that the indicated slag composition is shared chemically
- composition of cast iron which, according to the invention, is as indicated above, the following composition of the masses. : vanadium 0.35-0.90, ⁇ dite ⁇ 0.02-0.10 carbon ores 3.8-4.8 copper 0.0 -0.32 ⁇ cr
- Cast iron is usually smelted in ordinary ordinary furnaces, but also in small useful ones.
- vanadium cast iron has a composition of 5 va, as indicated above, poured into.
- a gaseous oxidizer such as an acid
- the predominantly magnetic fraction of vanadium sludge in the mixture is limited by the time of its dissolution.
- the vanadium cast iron is poured on the burner after 15 other compositions: mass. $: 4,2-4, C; 0.10-0, 2051; 0.40-0, 60 V; 0.10-0, 20 ⁇ , 0.10-0.20 ⁇ ? 0.05-0.15 Cg; 0,03-0,06- ?; 0.02-0.0433; 0.08-0, ⁇ 2 ⁇ ; 0.08-0, ⁇ 2 ⁇ 1; 0.001-0.12 C ⁇ .

- the resulting metal product is drained to the bottom through a failure, and the vanadium slag is delivered to the vessel.
- the described cycle transfers and after the end of the blowing of acid, the metal is blown away with argon or other inert gas with a minimum of 2.0 or less.
- the grains of the vanadium spinelide are crystallized in the form of suitable geo- logical bodies, and their size is 30-60 microns.
- the resulting metal after draining, processes slag-forming mixtures and liquefies or uses yutas for making steel in the iron ore furnace.
- vanadium cast iron was poured, containing mass. : 3.8-C; 0.35 - 31; 0.35 - ⁇ ; 5 0.07- ⁇ ; 0.12 - ⁇ ; 0.03 - Cr; 0,02 - ⁇
- the pig iron was ⁇ 300 ° ⁇ .

In the forefront, they pre-paid 1.6 t ($ 1) of steel steel.
- the intensity of the supplied overhead oxygen 35 was 2.5 m 3 / t.min. and the specific area of the earth became 0.20 m / ⁇ . - 23 - After 3 minutes of blowing (15 times during blowing), they planted 9.6 ⁇ of burns ($ 6) and went on blowing.
- the organic composition of the slag remained the same, the size of the spinel grains of the correct form was 60-80 microns.
- the metal has a temperature of ⁇ 620 ° ⁇ and contains ' ,. $ 0.44 C, 0.04 ⁇ and $ 0.028 ⁇ .
- the slag contained the masses: 26.8- vanadium oxide; 14, 1-oxide ⁇ pamnium, iron granule -3, 8; calcium oxide-6.4; iron oxide-18, 6; oxides ⁇ , Cr, ⁇ -other.
- the degree of mismatch 5 vanadium amounted to 89, 5 $.
- the inventive invention may be used in the case of a black metal and in the processing of titanium-magnetic material without iron. 10
- a method of compartmentalizing the device and successfully failing to be implemented in existing processes is inadequate. 25 Use, and also the use of the proposed products gives a significant economy of the original reaction.
