Abstract
The present invention relates to a method of preparing titanium and titanium alloy using furnace clinker containing titanium (blast furnace clinker containing titanium, etc. are included), which has a technical scheme that after the furnace clinker containing titanium of which the TiO2 content is 10 to 90 wt%, 0 to 50% of carbon, 0 to 40 wt/% of metallic aluminium, 0 to 40% of iron, 0 to 20% of magnesium are uniformly mixed, the fusing hot reduction is carried out, wherein the furnace clinker containing titanium is blast furnace clinker or smelting furnace clinker produced by using other methods. The melting hot reduction is carried out in equipment such as plasma furnaces, direct-current arc furnaces, alternate-current arc furnaces, etc. The compound containing titanium in the furnace clinker is resolved into the metallic titanium or the titanium alloy by the fusing thermal reduction process. The present invention can improve the recovery rate of the titanium in the furnace clinker, the recovery rate can reach 85 to 90 %, and the content of the residual titanium in the residual clinker can be less than 4%.
Description
Technical field
The invention belongs to the method for preparing titanium metal, relate in particular to a kind of method of utilizing Ti-containing slag to prepare (comprising titanium-containing blast furnace slag etc.) titanium metal.
Background technology
Since the sixties in last century, the scientific worker has been used as number of research projects to the comprehensive utilization of Ti-containing slag (comprising titanium-containing blast furnace slag etc.) both at home and abroad, from the research work content, most research work are carried out around extract metal titanium, titanium alloy and titanium-containing compound from Ti-containing slag, secondly are to utilize Ti-containing slag as material of construction.
Ti-containing slag is by its kind difference, TiO wherein
2Content is also different, and its fluctuation range can reach 10～90%, and titaniferous ore wherein is mainly uhligite, rutile and climbs titandiopside etc., and slag titaniferous amount is lower than at 30% o'clock, and the tiny disperse shape that is of its titaniferous ore crystallization is distributed in the slag, is difficult to separate.Extracting the representative research work of titanium or titanium alloy from Ti-containing slag is " silicothermic process reduction blast furnace slag direct current furnace is smelted ferro-silico-titanium ".
Adopt silicothermic process reduction blast furnace slag direct current furnace to smelt ferro-silico-titanium, carry out " the steel climbing high slag direct current furnace is produced the research of titanium silicon and cement " subject study, carried out " research of titanium silicon grade ", " titanium silicon application test ", " the steel climbing high slag direct current furnace is produced the research of titanium silicon smelting technology " and multinomial monographic studies such as " researchs of reduction residue system cement ".On the 200kVA single electrode direct current arc furnace, adopt and contain TiO
222.57% steel climbing high slag is a raw material, makes reductive agent with the ferrosilicon that contains 75%Si and smelts the ferro-silico-titanium test.Obtain alloy 2.996t altogether, 23.45%Ti, 44.06%Si in the alloy, the rate of recovery of titanium be 54.03% (Xu Chushao, Liu Tianfu. smelt complex ferroalloy with blast furnace titaniferous slag. mining metallurgical engineering .1988,11 (2)).But contain TiO in the reduction residue
27.09%, still higher, can not be used for activity of cement Additive, because the TiO in slag
2Content can obviously reduce the aquation intensity of cement greater than 4% o'clock.
Summary of the invention
The Ti-containing slag that utilizes that the purpose of this invention is to provide a kind of recovery rate that can improve titanium in the Ti-containing slag, can reduce the residual titanium amount in the residue prepares the method for titanium or titanium alloy.
For achieving the above object, the technical solution adopted in the present invention is with TiO
2Content is the Ti-containing slag of 10～90wt%, and the metallic aluminium, 0～40% iron and 0～20% the magnesium that add 0～50% carbon, 0～40wt% are reductive agent, and the add-on of reductive agent is not zero simultaneously, carries out the melting heat reduction after mixing.。
Wherein, Ti-containing slag or be blast-furnace slag or the smelted furnace cinder that produces for additive method.Described melting heat reduction is or carries out at plasma heating furnace or at direct current electric arc furnace or in ac arc furnace.
Owing to adopt technique scheme, by the melting heat reduction method titanium-containing compound in the slag is reduced to metal titanium or titanium alloy, can improve the recovery rate of titanium in the Ti-containing slag, its recovery rate can reach 85～90%, and the residual titanium content in the residue can be lower than 4%.
