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 low, be convenient to promote.Concrete manifestation is as follows:
One. the selection of lubricating oil of the present invention
Because the stressed large temperature of rotary kiln tyre is high, therefore tight to oily requirement.What we selected now is at 100 ℃, and more than viscosity reaches 100 centistokes, flash-point is taken turns the carrier with lubricating grease higher than the ucon oil of 320 ℃ as high temperature; Meanwhile, the combined high temperature lubricating grease of having selected the dropping point of petrochemical iy produced to be greater than 300 ℃, is controlling temperature, pressure, in strict technology situation, makes grease mutually fused, and one each other, is modulated into thickness paste or semi-fluid as required.As the such grease of carrier, can meet wheel band and the lubrication needs of associated components under 250 ℃ of left and right temperature conditionss.
Two. the selection of extreme-pressure additive of the present invention
For wheel band, due to its special harsh process condition, merely can not fundamentally solve its " hard friction ", " metal to-metal contact " situation by grease lubrication.Grease its vaporization losses in the time that temperature exceedes 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, greatly reduces thereby make it frictional coefficient, is issued to good lubricant effect in bad working environments.Being only limited on the laminate structure such as sulfide, inorganics material of the former employing of solid lubricant, in fact increases and selects to have the ultra-fine soft metal powder of nanometer and high molecular polymer powder, and they are combined with each other, and collaborative meeting produces better lubricant effect mutually.
There is the soft metal powder of nanometer as lubricant; it can be deposited on the rough tiny flaw of wear surface district at friction surface under high loading; reach filling repair; and molten spread becomes low shearing resistance, firmly adsorbs protective membrane under contact surface high temperature, high pressure; the wearing and tearing of critical surface reduce to rub; there is good anti-wear and wear-resistant performance, therefore select to have added the softer metals quantitatively with nano particle.The various solid lubricants that we select simultaneously have good heat conductance, are conducive to wheel distributing with heat.
Three. the selection of binding agent of the present invention
To, organically indissoluble several solid lubricants that we select, also need one not only to have at normal temperatures and pressures certain cohesive force, and under high temperature, high pressure, also there is the binding agent (the former band oil of taking turns does not have adding additives) of quite strong cohesive force.This binding agent will evaporate when most at lubricating oil, with utmost dispatch generation physics or chemical transformation, solid lubricant is bonded in to wheel band and associated components surface, forms a kind of firm lubricant film.We mainly select high molecular polymer to mix as binding agent, like this under high-temperature and high-pressure conditions, it can make the solid lubricants such as sulfide that we select, inorganics, soft metal, compacting sintering is on the surface of friction of equipment, form the compound self-lubricating fricting polymerization film of diversification, as being embedded in equipment surface, what this film had physics also has a chemical effect; Strong, durable, difficult drop-off makes lubrication failure.
Four, because high temperature wheel band often changes under environment greatly and works in relative temperature, and often have containing the dust of number of chemical element and enter lubricating oil, therefore the present invention selects multiple heatproof oxidation inhibitor, adopts composite form to intercept and reduces to enter because of temperature variation, dust the detrimentally affect that lubricating oil brings; Due to the mechanism of action difference of different oxidation inhibitor, compound use has synergy synergy, so just makes lubricating oil have the antioxygen property of a wide region temperature, has extended the work-ing life of lubricating oil.
A kind of rotary kiln tyre lubricating oil of the present invention, referred to as HF-high temperature wheel band lubricant, proves through repetition test for many years, can be widely used in the lubricated of wheel band on aluminum oxide, cement, mine, chemical industry and metallurgy industry large-sized rotary kiln, the improved band lubricating grease of taking turns, not only select sulfide, the laminate structure materials such as inorganics are as solid lubricant, also soft metal powder and the high molecular polymer powder with nano particle have been selected, pass through high temperature, high-pressure sinter is organically combined with each other them, form firmly fricting polymerization film, it is wear-resistant, anti-extreme pressure, high temperature resistance, anti scuffing power can fully meet 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 in extension device life-span, assurance manufacture of cement long-term stability, safety, for enterprise creates good economic benefit.

A kind of rotary kiln tyre lubricating oil of the present invention, its effect is that example is carried out brief description by the experiment of carrying out below:
The wheel band oil of originally producing is mainly used on 2500t/d, 3000t/d rotary kiln, at that time China 5000t/d production line few.High temperature is taken turns the improvement with lubricating grease, is mainly for the 5000t/d of China's cement industry sudden emergence and lubricating of above new type nonaqueous cement rotary kiln tyre and associated components.200 yuan of external products, one kilogram, hundreds of unit even above, expensive, be that we take turns the several times with lubricating grease price.Yanshi petrochemical industry and with power cement jointly cooperate improve after, the present invention carries out application test on the 5000t/d production line of Hebi.5.8 meters of left and right of its tyre diameter, the about 50t of weight, with power group due to the lubricated shortage understanding to wheel band and associated components, field observation wheel band and each associated components are substantially in the unlubricated state of metal to-metal contact, obviously find out that wheel band and associated components have heavy wear, scuff mark, there is interlock impaired loci, ring washer greatest wear 6mm, there is high temperature oxidation peeling phenomenon on wheel band, support roller surface, and be mixed with kiln body slight jitter, so that rotary kiln can not be realized maximum speed running, maximum feeds intake, can not complete design productive target.With power cement selection be electric oil-filling pump, overhaul just at that time, first we carried out abundant filling between wheel band and backing plate.Because the maximum clearance between wheel band and backing plate is at highest point, that is to say the gap maximum of only having between rotary kiln highest point wheel band and backing plate, so we adopt 90 ° of the every runnings of rotary kiln, to abundant spray between wheel band and backing plate, once (instrument can be with adding the manual oil atomizer gun of proboscis,), annotate altogether four times, like this by running, between wheel band and backing plate, all have lubricant and exist.Then, according to rotary kiln running lubrication circumstances timing not timing spray, generally on every Tuesdays to three times, a wheel is with 2Kg left and right one time, between wheel band and support roller, between wheel band and ring washer, shelves wheel etc., at ordinary times can be as the case may be several days or longer time spray.It is strong that wheel band lubricating grease soaks into ability, if lubricated maintenance is smeared in side timing to wheel band, this lubricating grease also can partly be immersed between wheel band and backing plate, runs into and stops kiln maintenance fully filling again.By the continuous operation of a wheat harvesting period, wheel band and lubricated dose of uniform fold of associated components contact surface, no longer include scratch, interlock impaired loci under wear print that obvious metal to-metal contact stays and high temperature, High Pressure, and the running of kiln body is more steady.Provable this lubricant has formed fricting polymerization film at each surface of friction thus, and this film has played wear-resistant, anti-extreme pressure, anti scuffing, self-repair function.
The present invention has also carried out application test at same power Xinxiang 5000t/d production line.Its former use be imported product, nearly 200 yuan of per kilogram, the abrasive conditions of wheel band and associated components, with slightly good compared with the production line of Hebi, has been used after high temperature wheel band lubricating grease, through running after a while, has reached equally the good result of expection.This product is used on many 5000t/d production lines at present, and is promoted.
