Abstract

The invention relates to the technical fields of titanium iron material formula and preparation, and especially relates to a preparation method of a low-aluminum-consumption titanium-iron alloy; the preparation method comprises that 95-108 parts by weight of rutile, 35-55 parts by weight of aluminum particles, 13-26 parts by weight of potassium chlorate, 8-22 parts by weight of lime and 0.6-1.8 parts of fluorite powder are adopted to be subjected to melting production in a cast iron furnace cylinder by an upper ignition method, and at the same time, molten steel of 30-70 parts by weight of silicon steel molten by an intermediate frequency furnace is flushed into the cast iron furnace cylinder for melting. The aluminum component in the method can be used for reducing titanium dioxide and maintaining heat required for normal reaction, low-value iron is not required to be reduced, aluminum resources can be effectively saved, energy is saved, the environment is protected, and the cost is effectively reduced. The preparation method adopts the technical scheme that the intermediate-frequency furnace molten silicon steel molten steel is flushed into the cast iron furnace cylinder for melting, so that the microstructure of the product can be uniform and dense; and the preparation method is short in flow and low in energy consumption, and is suitable for industrialized popularization and application.

Description

technical field [0001] The invention relates to the technical field of formulation and preparation of ferrotitanium materials, in particular to a method for preparing a ferrotitanium alloy with low aluminum consumption. Background technique [0002] Ferro-titanium refers to an iron alloy containing 25%-45% titanium, which is often used as a deoxidizer, degasser and alloying agent. The traditional ferro-titanium production adopts the out-of-furnace method, which is also called titanium concentrate metal thermal reduction method, which uses metal aluminum powder to react with titanium concentrate (containing titanium dioxide and ferric oxide) to produce titanium by reduction. Ferroalloy has the steps of batching, mixing, smelting and producing products. This method is the standard production process of traditional ferro-titanium 30 (FeTi30) or ferro-titanium 40 (FeTi40). [0003] The traditional formula of ferro-titanium 30 (FeTi30) includes two parts: the main material and t...
