Description
Technical field
The present invention relates to technical field of aluminum electrolysis, be particularly suitable for aluminium cell wettability negative electrode with TiB2 (TiB
2) the particulate prilling process.
Technical background
Hall-Ai Lute aluminium metallurgy method is the unique method of industrial aluminium metallurgy in the worldwide from 1886 so far always, but its power consumption is high, and the negative electrode Years Of Service is not long, and electrolyzer is short work-ing life, thereby causes the aluminium production cost too high.Research shows, TiB
2The wettability cathode technique is the existing high temperature fused salt electrolysis legal system aluminium of innovation, realizes one of energy-conservation gordian technique significantly.
Current, TiB
2The application form of wettability negative electrode is more, by contrast, and TiB
2-C composite cathode material have bonding strength height, life-span long, be easy to characteristics such as maximizations, performance is excellence more, is one of the most potential wettability cathode material.And existing TiB
2The preparation method mainly contains from spreading method and carbothermic method, and its finished product are TiB
2Powder, general granularity is 1-100 μ m, is difficult to prepare the TiB of various volume particle sizes
2Particle.Therefore, present TiB
2-C composite cathode technology of preparing can only adopt fine-grained TiB
2Powder is as the source of titanium boride, because fine powder is too much, tiny crack appears in negative electrode easily behind the shaping and roasting, causes negative electrode intensity and corrosion resistance nature not to reach requirement, influences its work-ing life.For avoiding the appearance of composite cathode material crackle, improve material mechanical property and and high base strength, must reduce TiB
2The consumption of powder.Yet titanium boride content can not get effective raising in the composite cathode material, causes performances such as composite cathode and molten aluminum liquid wettability can't reach desirable requirement, is difficult to realize real water conservancy diversion negative electrode, and sodium and ionogen corrode big to the infiltration of composite cathode.
To TiB
2Propose TiB in the problem that-C composite cathode material too much causes because of fine powder material, patent (No.200710192546.1)
2-C composite cathode aggregate carries out grain size distribution, can fundamentally solve above-mentioned drawback.From the angle of grain size distribution, adopt macrobead carbon aggregate cheap and easy to get to substitute TiB
2It is feasible that particle carries out grain size distribution, but at TiB
2The lip-deep macrobead carbon of-C composite cathode aggregate is because of poor with aluminum-liquid wetting property, and influences the wettability between whole cathode material surface and the aluminium liquid, can't realize real wettability water conservancy diversion negative electrode.Above-mentioned showing, adopt TiB
2Particle is to TiB
2It is the effective way that realizes real wettability long life cathode that-C composite cathode aggregate carries out grain size distribution.Therefore, TiB
2The powder agglomeration technique is prepared sizes grating TiB
2The key of-C wettability composite cathode material.
Summary of the invention
To existing TiB
2-C composite cathode preparation and the deficiency that performance exists the invention provides that a kind of cost is low, intensity is big, anti-sodium perviousness strong, good conductivity, fully and the high-content TiB of aluminum-liquid wetting
2The particulate preparation method is in the hope of obtaining high-quality TiB
2-C composite cathode.
Technical solution of the present invention is following:
A kind of TiB
2The powder prilling process is characterized in that, may further comprise the steps:
Step 1: sticker, aggregate, charcoal fiber and organic solvent are mixed, and the mass ratio of each component is: aggregate: 80-95%; Sticker 5-20%; Thomel 0-3.0%; Organic solvent 0-5.0%;
Step 2: mix the moulding of kneading: the mixture of step 1 gained is mixed the moulding of kneading, make the moulding article;
Step 3: roasting:, make roasting product with the roasting under 900 ℃ of-1400 ℃ of temperature condition of moulding article;
Step 4: broken and screening:, obtain TiB with screening again after the roasting product fragmentation
2Particle.
Described sticker is organic binder bond, mineral binder bond or by the compound binding agent of organic binder bond and the compound preparation of mineral binder bond, and described organic binder bond is one or more the mixture in coal-tar pitch, petroleum pitch, epoxy resin, furane resin, polyimide resin, resol, carbolineum and the coal tar; Described mineral binder bond is the mixture of any one or multiple composition in alumina sol, Natural manganese dioxide colloidal sol, silica sol, the silit colloidal sol.
Described aggregate is by TiB
2Powder or TiB
2Powder and carbonaceous aggregate mix to be formed, wherein TiB
2Powder accounts for the 85-100% of total aggregate, and the carbonaceous aggregate accounts for 0-15%.
Described carbonaceous aggregate is forged at least a composition the in hard coal, metallurgical coke, needle coke, the carbon fiber powder by refinery coke, Graphite Powder 99, pitch coke, electric calcined anthracite, gas.
Described organic solvent is at least a formulated by in ethanol, ethyl acetate, the acetone.
Coal-tar pitch in the said sticker, petroleum pitch, furane resin, polyimide resin, resol mix with aggregate, charcoal fibre fractionation with the pressed powder form; Or mix with aggregate, charcoal fibre fractionation after adopting organic solvent dissolution to become liquid form, or mix and pinch with molten state form and aggregate, charcoal fibre fractionation.
Moulding process in the step 2 is to adopt vibratory compaction or compression molding, and the pressure magnitude range is: 0.5-10MPa (vibratory compaction), 50-180MPa (compression molding).
Described roasting process is: the speed with 8-15 ℃/h during beginning is warming up to 600 ℃, then with the speed of 15-25 ℃/h to 900-1400 ℃, insulation 6-15h is cooled to 600 ℃ with 30-40 ℃/h again, cools to room temperature then with the furnace.
Shattering process in the step 4 is carried out for adopting in jaw crusher, impact breaker, hammer mill, combined type crusher, impingement crusher, the cone crusher one or more.
The technical parameter explanation:
(1) forming pressure: 0.5-10MPa (vibratory compaction), 50-180MPa (compression molding).Pressure is crossed conference cracks the moulding article, and the too small moulding article density that then can cause is little, and intensity is low.
(2) heat-up rate: be lower than 600 ℃: 8-15 ℃/h; Be higher than 600 ℃: 15-25 ℃/h; Speed of cooling: 30-40 ℃/h is cooled to 600 ℃, cools to room temperature then with the furnace.When being lower than 600 ℃, the too fast meeting of heat-up rate causes a large amount of sticker volatile matters to overflow, and increases the sample porosity, reduces sample intensity; After being higher than 600 ℃, heat-up rate can be fast slightly, because should mainly be the sticker carbonization process in the stage; Cooling rate equally can not be too fast, can cause sample crackle or fracture to occur too soon; Intensification and cooling rate all can not be slow excessively, in order to avoid cause waste of energy.
(3) maturing temperature: 900 ℃-1400 ℃.Maturing temperature is too high high to equipment requirements, and cost is increased; Maturing temperature is low excessively to cause sample roasting degree not enough, and performance can not reach requirement.
Advantage of the present invention:
The present invention through the roasting crush method to TiB
2Powder carries out granulation, and technology is simple, cost is low, easy to operate, gained TiB
2Granule strength is big, TiB
2Content is high, anti-sodium perviousness strong, good conductivity, with aluminium liquid complete wetting.The present invention proposes electrolysis of aluminum wettability negative electrode is used TiB first
2Powder carries out granulation, has broken composite cathode and has used raw material TiB
2The situation of having only powder, the grain size distribution that can be large size composite cathode aggregate provides the TiB of controllable granularity
