High Level Material Ferro Vanadium 50

The reasonable temperature system and cooling system of vanadium oxidation when blowing low ferro vanadium 50 water in oxygen top converter furnace were discussed, the effects of molten iron composition, FeO content in vanadium slag and residual vanadium content in semi-steel on the grade of vanadium slag were discussed, the expression of the relationship between vanadium slag grade and various factors was obtained, and the predicted Nomo diagram reflecting the relationship between the initial vanadium content, vanadium recovery, vanadium slag yield and vanadium slag grade of molten iron was derived. The research results were applied to the industrial practice of vanadium blowing in 10t oxygen top converter, and the results were good.

1.In the process of electrothermal-thermite smelting of ferro vanadium 50, when the charge fully completes the thermite reaction and the slag is separated, the electrode heating is stopped, and then the spray gun is inserted into the slag layer and the reduced powder is sprayed, and the furnace body is rotated at the same time, and the reducing powder is fully mixed with the slag under the dual action of the injection air flow impact and the rotary stirring of the furnace body, and then the electrode is inserted to continue heating and smelting for 20~25 minutes, so that the residual vanadium in the slag is further reduced to form ferrovanadium. The present invention can effectively improve the reaction kinetic conditions of the refining charge, and the optimal component ratio and injection volume can make the reaction of the refining charge more sufficient, realize the vanadium recovery rate of ferrovanadium smelting, and reduce the production cost.
