Abstract

The invention relates to an intermixture briquette obtained by direct alloying of V2O5 and an application method thereof. The technical scheme is as follows: the raw materials and the contents of the intermixture briquette are as follows: 10-25 wt% of V2O5 powder, 5-20 wt% of reducing agent, 50-75 wt% of additive and 5-15 wt% of water glass. A preparation method of the intermixture briquette obtained by direct alloying of V2O5 comprises the following steps of: adding the V2O5 powder, the reducing agent and the additive according to the raw materials and the contents, adding water glass, uniformly stirring, briquetting and drying to obtain the intermixture briquette obtained by direct alloying of V2O5. According to the invention, the prepared intermixture briquette has the advantages of quick V2O5 reduction speed, high yield of vanadium, simple and easy operation, capability of obtaining the required middle-low carbon vanadium-containing micro-alloy steel at a single step, and remarkable economic benefit.

Description

technical field [0001] The technical field of the direct alloying additive of the present invention, particularly relates to a kind of V 2 o 5 Directly alloyed mixture compacts and methods of use thereof. Background technique [0002] At present, there are three main ways to produce vanadium-containing alloy steel: the first is to add vanadium-ferroalloy in the steelmaking furnace, which is the most common method, and it is the main method for producing vanadium alloy steel at this stage; the second is to directly add vanadium in the steelmaking furnace Vanadium slag (containing V 2 o 5 15~20wt%) and reducing agent for alloying; the third is to add V 2 o 5 and reducing agent, and then add a depleting agent during the reducing period for alloying. [0003] When ferrovanadium is used as raw material for alloying, it is necessary to use special production equipment to smelt ferrovanadium alloy. The smelting process of ferrovanadium alloy is relatively complicated, and ele...
