In Ti-containing slag, " high temperature cabonization-low temperature chlorination produces TiCl4" technique in, high temperature cabonization mainly will be in clinker
Titanium dioxide is changed into titanium carbide, obtains titanium carbide clinker, is further used for low temperature chlorination and prepares titanium tetrachloride.By in raw material
TiO2The influence of content, the TiC grade in titanium carbide clinker obtained is lower, leads to chlorination efficiency during subsequent low temperature chlorination
Low, chlorine consumes big, chlorination higher cost, therefore needs further to sort or be enriched in titanium carbide slag before low temperature chlorination technique
TiC.However, since the TiC particle size in titanium carbide clinker is smaller, usually 0.2 μm~10 μm, and Dispersed precipitate exists
In slag, when the TiC in titanium carbide clinker is sorted or is enriched with, the difficulty using techniques such as magnetic separation, acidleach is larger.
Various dedusting ash, including sintering dust separation ash, blast furnace dedusting ash, converter dust-removing ash, electric furnace can be generated in steel production
Dedusting ash etc..If the dedusting ash generated in titanium slag smelting process contains 25%~40% ilmenite concentrate, can with after pelletizing back into
Furnace is smelted.Patent document CN104310535A discloses the resource utilization method of a kind of blast furnace dedusting ash and coking dedusting ash,
Blast furnace process dedusting ash and coking dedusting ash are granulated and are sintered, the degradation for organic matter in coking wastewater.Patent document
CN107385222A discloses a kind of utilization method of carbon containing dedusting ash of rotary kiln, carbon containing dedusting ash is covered in pelletizing surface or
Person and the balling process for being directly used in lateritic nickel ore.Dedusting ash is different according to its source technique, and ingredient is also corresponding different, partially removes
For dust since valuable element content is low, utilization is at high cost, is mostly handled using heap abandoning.
Summary of the invention
Present invention solves the technical problem that being that TiC partial size prepared by Ti-containing slag carbon thermal reduction is smaller, lead to subsequent purification
The difficulty for being enriched with TiC is big.
Technical proposal that the invention solves the above-mentioned problems is to provide the method for promoting that TiC grows up in slag, in titaniferous materials
During preparing titanium carbide clinker by carbon thermal reduction, the electric stove dust ash generated in smelting process is added in electric furnace, with
Titaniferous materials, reducing agent are smelted together, and cooling of slagging tap after smelting obtains titanium carbide clinker.
Wherein, in titaniferous materials content of titanium dioxide between 15%~45%.
It wherein, include fixed carbon 10~45%, K in dedusting ash2O 5~18%, Na2O 5~15%.
Wherein, reducing agent is carbonaceous reducing agent, selects coke powder, lean coal, at least one of anthracite, usage amount by C with
TiO21.3~1.4 times of determinations of chemical reaction metering ratio.
Wherein, reducing agent control adds in 50~75min, and the control of present invention temperature is added 1550 DEG C~1600
℃。
Wherein, it is 1620 DEG C~1670 DEG C that bath temperature is promoted after reducing agent adds, 25~50min of duration.
Wherein, it is slagged tap cooling after smelting by slag pan.
Wherein, single slag pan volume > 8t, single > 10h slag pan cooling time.
Beneficial effects of the present invention:
The present invention by titanium slag smelting process be added smelting process generate dedusting ash, through carbon thermal reduction, slag tap it is cold
But the titanium carbide granule being prepared is up to 7~30 μm；The titanium carbide that the present invention is prepared is available higher through wet magnetic separation
The carbonization titanium products of grade can reduce chlorine consumption and level of residue for producing titanium tetrachloride, improve chlorination efficiency, final to realize
The efficient utilization of titanium carbide slag, improves the comprehensive utilization ratio of titanium resource；The present invention can carry out the dedusting ash that smelting process generates
It is effective to recycle, alleviate environmental pressure.
Specific embodiment
Electric furnace smelting titaniferous materials prepare the electric stove dust ash of generation 1%~3% during titanium carbide slag, pass through detection point
