Abstract

The invention belongs to the technical field of ferrous metallurgy, particularly relates to a Taihe vanadium-titanium pellet and a production method thereof, and aims to solve the technical problem ofproviding the Taihe vanadium-titanium pellet and the production method thereof. The production method comprises the following steps: according to the percentage by weight, uniformly mixing 50-90% ofTaihe concentrate, 10-50% of superfine grain-size vanadium-titanium magnetite concentrate and a binder, wherein the weight of the binder is 2.0-2.5% of the total weight of the concentrate, pelletizingto obtain green pellets, and carrying out drying, preheating, roasting and cooling on the green pellets to obtain the Taihe vanadium-titanium pellet. The Taihe vanadium-titanium pellet prepared through the production method is uniform in particle size and high in compressive strength.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a Taihe vanadium-titanium pellet and a production method thereof. Background technique [0002] Taihe Mining Area is located in the northwest of Xichang City, 12km away, and is under the jurisdiction of Taihe Town, Xichang City. After detailed survey, the mining area has accumulated proven reserves of 890 million tons and industrial reserves of 279 million tons. It is a super-large vanadium-titanium magnetite deposit. At present, the annual output of Taihe Mine is 800,000 tons, TFe is about 55%, and TiO 2 The content is about 12.5%, V 2 o 5 The content is about 0.55%, which belongs to the high-titanium vanadium-titanium magnetite concentrate. The ore is currently mainly used in the Xichang Steel Vanadium Sintering Plant. However, due to its poor particle size composition and high titanium content, perovskite is formed during the sintering process...
