The present invention manufactures easily it, has obviously improved working efficiency and quality product, greatly save energy.Reduce maintenance and maintenance cost, save production cost; Guarantee to produce normal operation.Invest lowly, be convenient to promote.Concrete manifestation is following:
One. the selection of lubricating oil of the present invention
Because the stressed big temperature of rotary kiln tyre is high, and is therefore tight to the requirement of oil.What we selected now is under 100 ℃, and viscosity reaches more than 100 centistokes, and flash-point is higher than 320 ℃ ucon oil as the carrier of high temperature wheel band railway grease; Simultaneously, the dropping point of having selected petrochemical iy produced for use at controlled temperature, pressure, under the strict process condition, makes grease fused each other greater than 300 ℃ combined high temperature railway grease, and one is modulated into thickness paste or semi-fluid as required each other.As the such grease of carrier, can satisfy wheel band and the lubrication needs of associated components under 250 ℃ of left and right sides temperature conditionss.
Two. the selection of extreme-pressure additive of the present invention
Bring for wheel, because its special harsh process condition merely leans on grease lubrication can not fundamentally solve its " hard friction ", " metal to-metal contact " situation.Grease its vaporization losses when temperature surpasses 200 ℃ as carrier is quite serious, can only play limited lubrication in the short period of time.Therefore, select the solid lubricant of high temperature resistant, anti-extreme pressure, timeliness length very necessary.
Solid lubricant adheres to the friction surface of mutual motion, makes friction occur in solid lubricant inside, reduces greatly thereby make it frictional coefficient, is issued to good lubricating effect in bad working environments.Being only limited on the laminate structure materials such as sulfide, inorganics of the former employing of solid lubricant increases in fact and selects to have nanometer superfine soft metal powder and high molecular polymer powder, and they are combined with each other, and collaborative each other meeting produces better lubricant effect.
Soft metal powder with nanometer is as lubricant; It can be deposited on the rough tiny flaw of wear surface district at friction surface under high loading; Reach the filling repair, and molten spread becomes low shearing resistance, firm absorption protective membrane under contact surface high temperature, high pressure, the wearing and tearing of the critical surface that reduces to rub; Good anti-wear and wear-resistant performance is arranged, therefore select to have added the softer metals that quantitatively has nano particle.Our the various solid lubricants of selection all have good heat conductance simultaneously, help taking turns distributing of band heat.
Three. selection of binder of the present invention
Organically fused together several kinds of solid lubricants that we select, also need a kind of certain cohesive force be arranged at normal temperatures and pressures not only, and under high temperature, high pressure, also have the sticker (the former band oil of taking turns does not have adding additives) of quite strong cohesive force.This sticker will be treated with utmost dispatch generation physics or chemical transformation, to be bonded in wheel band and associated components surface to solid lubricant when most in lubricating oil evaporation, forms a kind of firm lubricant film.We mainly select high molecular polymer to mix as sticker; Like this under high-temperature and high-pressure conditions; It can make solid lubricants such as sulfide that we select, inorganics, soft metal, and compacting sintering forms the compound self-lubricating fricting polymerization film of diversification on the surface of friction of equipment; As being embedded in equipment surface, this film has the effect that chemistry is also arranged of physics; Strong, durable, difficult drop-off makes lubrication failure.
Four, because often being in relative temperature, high temperature wheel band changes environment work down greatly; And often there is the dust that contains the number of chemical element to get into lubricating oil; Therefore the present invention selects multiple heatproof oxidation inhibitor, adopts composite form to intercept and reduces to get into the detrimentally affect that lubricating oil brings because of temperature variation, dust; Because the mechanism of action of different oxidation inhibitor is different, compound use has the synergy synergy, so just makes lubricating oil that the antioxygen property of a wide region temperature is arranged, and has prolonged the work-ing life of lubricating oil.
A kind of rotary kiln tyre lubricating oil of the present invention abbreviates HF-high temperature wheel band lubricant as, and the TE through for many years proves, can be widely used in wheel band lubricated on aluminum oxide, cement, mine, chemical industry and the metallurgy industry large-sized rotary kiln; The improved band railway grease of taking turns has not only selected laminate structure materials such as sulfide, inorganics as solid lubricant, has also selected soft metal powder and high molecular polymer powder with nano particle for use; Through high temperature, high-pressure sinter they organically are combined with each other; Form firm fricting polymerization film, its wear-resistant, anti-extreme pressure, high temperature resistance, anti scuffing power can fully satisfy the lubricated of rotary kiln tyre and associated components, reduce wearing and tearing, scratch; Effectively reduce rotary kiln shake, distortion, distortion; Can play the effect that prolongs equipment life, guarantee that manufacture of cement is steady in a long-term, safety, for enterprise creates good economic benefit.

A kind of rotary kiln tyre lubricating oil of the present invention, its effect is carried out brief description through the following experiment of carrying out for example:
The wheel band oil of originally producing is mainly used on 2500t/d, the 3000t/d rotary kiln, at that time China 5000t/d production line and few.The improvement of high temperature wheel band railway grease mainly is to the 5000t/d of cement in China industry sudden emergence and lubricating of above new type nonaqueous cement rotary kiln tyre and associated components.External product costs an arm and a leg more than 200 yuan even one kilogram in hundreds of unit, is the several times that we take turns band railway grease price.The Yanshi petrochemical industry and with power cement cooperate jointly improve after, the present invention carries out application test on the 5000t/d production line of Hebi.About 5.8 meters of its tyre diameters, the about 50t of weight is with power group because to taking turns the lubricated shortage understanding of band and associated components; Field observation wheel band is in the unlubricated state of metal to-metal contact basically with each associated components; Find out that obviously wheel band and associated components have heavy wear, scuff mark, have the interlock impaired loci, ring washer greatest wear 6mm; There is the high temperature oxidation peeling phenomenon on wheel band, support roller surface; And be mixed with kiln body slight jitter, and so that can not realizing maximum speed running, maximum, rotary kiln feeds intake, can not accomplish the design productive target.What select for use with power cement is electronic petrol-feed pump, overhaul just at that time, and we are at first to having carried out abundant filling between wheel band and the backing plate.Because the maximum clearance between wheel band and the backing plate is at highest point; That is to say that the gap of having only the rotary kiln highest point to take turns between band and the backing plate is maximum, so we adopt 90 ° of the every runnings of rotary kiln, once (instrument can be with adding the manual oil atomizer gun of proboscis to abundant spray between wheel band and the backing plate;); Annotate altogether four times,, all have lubricant between wheel band and the backing plate and exist like this through running.Then, according to the regularly not timing spray of rotary kiln running lubrication circumstances, generally on every Tuesdays to three times, wheel is with about 2Kg, between wheel band and the support roller, between wheel band and ring washer, the shelves wheel etc., at ordinary times can be as the case may be several days or longer time spray.Wheel band railway grease soaks into that ability is strong, if lubricated maintenance is regularly smeared in wheel band side, this railway grease also can partly be immersed between wheel band and the backing plate, runs into to stop kiln maintenance fully filling again.Through the continuous operation of a wheat harvesting period, wheel band evenly covers for lubricated dose with the associated components contact surface, no longer includes scratch, interlock impaired loci under wear print that tangible metal to-metal contact stays and high temperature, the high pressure effect, and the kiln body turns round more steady.Provable thus this lubricant has formed the fricting polymerization film at each surface of friction, and this film has played wear-resistant, anti-extreme pressure, anti scuffing, self-repair function.
The present invention is also carrying out application test with power Xinxiang 5000t/d production line.Its former usefulness be imported product, nearly 200 yuan of per kilogram, it is good slightly that wheel band and the abrasive conditions of associated components are compared with the Hebi production line, used high temperature wheel band railway grease after, through running after a while, reached the good result of expection equally.This product is used on how tame 5000t/d production line at present, and obtains promoting.
