Problems solved by technology
The disadvantages of this process are: 1. Use conventional vanadium-iron alloy
The steps of extracting vanadium trioxide in the process of producing vanadium-iron in the prior art include: crushing, roasting, leaching, precipitation, melting and smelting, which are very complicated, and also produce a large amount of waste acid, waste water, waste residue and other pollution Harmful substances in the environment, and its governance is very difficult
2. When vanadium-iron is added to molten steel after deoxidation, because the deoxidizer cannot be uniformly distributed in molten steel in time, the vanadium in the added vanadium-iron cannot be protected by deoxidizing elements in time, and the yield of vanadium is not as a result. high

The invention provides a vanadium-silicon-barium-ferrum composite alloy, which comprises (by weight percentage) Si 30-75%, Ba 3-25%, V 0.5-10%, balancing Fe and unavoidable impurities. The preparing process of the alloy includes deacidizing vanadium slag, dinas rock and heavy spar in furnace.
Description
technical field [0001] The invention relates to an alloying agent for steelmaking, in particular to a silicon-barium-vanadium-iron composite alloy. Background technique [0002] Niobium is a very beneficial element in steel, which can refine the crystal structure of steel, thereby improving the strength, toughness, plasticity and wear resistance of steel. When the vanadium content in the steel reaches 0.03-0.05%, it can reduce the aging sensitivity of the steel and improve the surface quality of the steel ingot. When the vanadium content in steel reaches 0.01-0.04%, vanadium can improve the high temperature quenching and annealing properties of steel. [0003] At present, the conventional process of alloying molten steel with vanadium is to deoxidize molten steel with deoxidizing elements such as aluminum, manganese, silicon, etc., and then alloy it with vanadium-iron alloy. The disadvantages of this process are: 1. Use conventional vanadium-iron alloys. The production pr...
