Abstract

The invention relates to a method for smelting and preparing vanadium iron alloy by taking Panxi vanadium as a raw material, belonging to metallurgy field. The method comprises the following steps of: weighting various material and auxiliary materials according to a formulation, putting the weighted raw materials and the auxiliary materials into a material mixing device so as to be fully stirred till being uniformly stirred, putting the uniform mixed material into a reaction unit which is preheated to a temperature of 200 to 300 DEG C, carrying out fire beginning reaction, adding 30 to 50kg of retarder after reaction is over, cooling for 48 to 72 h, and finally separating slag and alloy; and putting inspected, finishing, and packaged vanadium iron alloy products in storages. Compared with the prior art, the steps of the process are simplified, thereby both increasing safety and reducing production cost; the high vanadium iron alloy product has high grade vanadium, low sulphur and phosphorous level, low aluminium and silicon content, effectively reduces the damage of possible drag-in impurities to types of steels and has positive promotion significance for deoxygenation alloying in the steel production.

Description

technical field [0001] The invention relates to a metallurgical method, more specifically, the invention relates to a method for preparing vanadium-iron alloy by smelting Panxi vanadium raw materials, which belongs to the field of metallurgy. Background technique [0002] Vanadium is an important alloying element and alloy additive in the steel production process, which can improve the structure of steel and improve the performance of steel. Ferrovanadium is a ferroalloy composed of vanadium and iron. As a catalyst, additive and additive, ferrovanadium is widely used in steel, alloy and chemical industries, and the market demand is huge. It is mainly used as an alloy additive in steelmaking, and high-vanadium iron is also used as an additive for non-ferrous alloys. Commonly used ferrovanadium contains 40%, 60% and 80% vanadium. Ferrovanadium is an important alloy additive in the iron and steel industry. It is divided into ferrovanadium containing about 50% vanadium, namely...
