Abstract

The invention discloses a commercial manufacturing method for directly producing iron and titanium aluminum alloy from vanadium-titanium magnetite placer deposits, and comprises the following procedures of: first, carrying out pellet preparation to the vanadium-titanium magnetite placer deposits extracted from nature; then, drying the pellets, reducing and fractional melting, and screening and extracting the block iron; last, adopting an aluminothermic reducing method to vanadium-titanium bearing slag so as to obtain vanadium-titanium aluminum alloy. The content of block iron obtained in the method is about 93 percent; the recycling rates of iron, vanadium and titanium are 90 percent, 85 percent and 85 percent respectively. The commercial manufacturing method has the advantages of high iron, vanadium and titanium integrated recycling and utilization rate, high production rate and no pollution to environment, thus being easy for industrialization promotion and having obvious social andeconomical efficiency.

Description

technical field [0001] The invention relates to mineral separation and alloy smelting methods, more particularly, refers to an industrialized production method that firstly separates lump iron from vanadium-titanium magnetite sand ore, and then smelts vanadium-titanium-aluminum alloy by adding aluminum. Background technique [0002] Titanium is an important structural metal. Because of its high strength, low density, good corrosion resistance and high heat resistance, titanium alloy is a good structural and functional material, and is widely used in aerospace, medical equipment, chemical industry Equipment, military industry and sports equipment and other fields. Many countries in the world have recognized the importance of titanium alloy materials, researched and developed them one after another, and obtained practical applications. Since Kroll successfully developed the smelting metal Ti in the 1950s, the industrial production method of titanium widely used in the world i...
