Description
Technical field
The present invention relates to lubricating grease field, be specifically related to a kind of lubricating grease that is exclusively used in metallurgy industry sinter machine and preparation method thereof.
Background technology
The sintering work Production Flow Chart of sinter machine is longer, and equipment is comparatively numerous and diverse, adds that it,, in special working conditions such as high temperature, many dirt, heavy duty and sour gas environment, makes it quite harsh to the requirement of lubricating grease.The sintering work of sinter machine is to realize by high negative pressure operation, and the aeroseal sheet of sinter machine has deadweight and elastic force, under pressure, produces wearing and tearing and distortion, thereby on contact surface, produce gap owing to sliding, and causes gas leakage.This phenomenon is except outside the Pass having with physical construction, and also the factor such as the temperature in sintering process (temperature of sealing element is up to 200 DEG C of left and right) and raw material, agglomerate dust is relevant with agglomerate.Under high temperature lubricating grease softening, flow out and cause for fat fault bad for fat, and dust is sneaked into the poor sealing that causes etc. and all can be accelerated the inordinate wear of hermetic unit.
Seal device of sintering machine is generally supplied with for fat device by automatic with lubricating grease, current considerable smelter adopts traditional soap base class lubricating grease, but the high-temperature behavior of this class lubricating grease is poor, easily softening loss, contact surface produces gap, pressure reduction destroys the sealed structure that lubricating grease forms, leaks gas, and accelerated wear test, do not reach requirement lubricated and sealing, and soap base class lubricating grease metal ion, at high temperature easy coking and blocking pipeline, pumping is poor.Cause air leak rate of air curtain large so in use find bad lubricating, slideway serious wear, production efficiency is low, it is reported, the maximum air leak rate of air curtain of external sinter machine is no more than 30%, and the air leak rate of air curtain of the sinter machine of domestic current running is generally 40-60%, except will improving equipment, also need to strengthen the improvement to PERFORMANCE OF GREASES.
In recent years, along with China's metallurgy industry develop rapidly, the energy-saving and cost-reducing problem that becomes concern.The lubricating grease that sinter machine is used is not had higher requirement, and sinter machine lubricating grease should have good high-temperature behavior, and vaporization losses reduces, thinning under high temperature, do not run off and not oxidizable, plays good lubricated and sealing function; Require to there is higher supporting capacity and friction resistant performance simultaneously, meet equipment lubricated requirement under many dirt and impact load; There is good barrier propterty, prevent acid attack gas pickling metallic surface; Have good pump-conveying property and low coking tendency, not blocking pipeline, meets and concentrates for grease lubrication system; There is longer work-ing life etc.

Application note of the present invention:
Lubricating grease of the present invention is mainly applicable to the lubricated of the high temperature services such as each position bearing of elastic slideway of metallurgical industry large-type sinterer and other soaking pit, annealing furnace, stoving oven, also be applicable to bearing, gear, chain lubricated of various device under excessive temperature, heavy duty, low-speed conditions, as various rotary kilns or the tunnel kiln car bearing etc. of large-scale refractory factory, ceramics factory, electroceramics factory.Applicable temperature :-30 DEG C～220 DEG C
Beneficial effect of the present invention:
1, excellent resistance to elevated temperatures and oxidation stability: dropping point index is one of index directly perceived of its high-temperature behavior of reflection, and this product dropping point can reach more than 300 DEG C, can use under 220 DEG C of Working environments the long period; High-temperature oxidation stability is one of main use properties of lubricating grease, and lubricating grease used and have larger impact.The oxidation stability of lubricating grease is with to prepare grease thickener relevant with basic oil properties, and this product viscosifying agent, because of metal ion not, can be avoided the metal catalytic effect of base oil oxidation under high temperature, so have good high-temperature oxidation resistant stability.
2, excellent colloid stability and pumping: lubricating grease colloid stability is to weigh a tool important indicator of a lubricating grease use properties and shelf characteric quality.This product viscosifying agent is organism, has good affinity with base oil, contains aryl simultaneously, and adds a certain proportion of synthetic ester lubricant, so have excellent colloid stability; Sinter machine centralized lubrication system pumping line is very long, particularly needs in the winter time lubricated product to have good temperature pumping, even if this product, under the condition of-30 DEG C, also can meet the requirement of sinter machine centralized lubrication system.
3, excellent sealing property: not thinning under this product high temperature, do not run off, ferrous metal is kept to good adhesive capacity, under 220 DEG C of Working environments, use noncoking, can not cause slideway wearing and tearing, and water pouring loss is low, water repelling property is good, contacting with water, even mix with water after denseness reduce very littlely, can effectively get sealing function.
4, there is excellent lubricated and extreme pressure and antiwear behavior: the sintering work work low speed high temperature sliding friction of sinter machine, and with a large amount of dust, want to bear larger impact load simultaneously, the mineral oil of the high viscosity deep refining that this product is selected, under high loading, still can well form excellent oil film thickness, test shows, P
bmore than reaching 1000N, P
dmore than reaching 6000N.
5, the work-ing life of overlength: the high-temperature behavior of lubricating grease refers to lubricating grease bearing life at high temperature, the reflection of lubricating grease Integrated using performance, the level of the fundamental propertys such as colloid stability, mechanical stability and oxidation stability that can constitutionally reflection lubricating grease.This product is at the temperature of 160 DEG C, life-span reaches 1000 hours above (test method ASTM D 3336), there is good bearing working ability, there is longer work-ing life, be the more than 10 times of general soap base grease its work-ing life, therefore has high economic worth and use value.
