Description
Technical field
The present invention relates to the lubricating grease field, be specifically related to a kind of railway grease that is exclusively used in the 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 is in special working conditions such as high temperature, many dirt, heavy duty and sour gas environment, makes that its requirement to railway grease is quite harsh.The sintering work of sinter machine is to realize through the high negative pressure operation, and the aeroseal sheet of sinter machine has deadweight and elastic force, under pressure, produces wearing and tearing and distortion owing to slide, thereby produces the gap on the contact surface, causes gas leakage.This phenomenon is except outside the Pass having with physical construction, and is also relevant with factors such as temperature (temperature of sealing element be up to about 200 ℃) and the raw material of agglomerate in sintering process, agglomerate dust.Under the high temperature railway grease softening, flow out and the confession fat that supplies the fat fault to cause bad, and dust is sneaked into the inordinate wear that the poor sealing that causes etc. all can quicken hermetic unit.
Seal device of sintering machine uses railway grease generally to supply with through automatic confession fat device, and present considerable smelter adopts traditional soap base class railway grease, but the high-temperature behavior of this type railway grease is poor; Softening easily the loss, contact surface produces the gap, and pressure reduction makes the formed sealed structure of railway grease destroy; Leak gas, accelerated wear test does not reach requirement lubricated and sealing; And soap base class railway grease metal ion, at high temperature being prone to coking and blocking pipeline, pumping is poor.Cause air leak rate of air curtain big so in use find bad lubricating; The 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 present running is generally 40-60%, except will improving equipment, also need 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.Railway grease to sinter machine uses is not had higher requirement, and sinter machine railway grease should have the good high-temperature performance, and vaporization losses reduces, and is thinning under the high temperature, do not run off and be difficult for oxidation, plays good lubricated and sealing function; Require to have advantages of high bearing capacity and friction resistant performance simultaneously, satisfy the requirement that equipment lubricates under many dirt and impact load; Have good barrier propterty, prevent acid attack property gas pickling metallic surface; Have good pump-conveying property and low coking tendency, blocking pipeline does not satisfy the grease lubrication system that supplies that concentrates; Has long work-ing life etc.
Summary of the invention

(8) with the mixture circulation shear of step (7) after 30-60 minute, homogeneous, the degassing, discharging under the 20-35MPa pressure promptly get product.
Application note of the present invention:
Railway grease of the present invention mainly is applicable to the lubricated of high temperature service such as each position bearing and other soaking pit, lehre, the stoving oven of the elastic slideway of metallurgical industry large-type sinterer; Also be applicable to bearing, gear, chain lubricated of various device under excessive temperature, heavy duty, the low-speed conditions, like the various rotary kilns of large-scale refractory factory, ceramics factory, electroceramics factory or tunnel kiln car bearing etc.Applicable temperature :-30 ℃ ~ 220 ℃
Beneficial effect of the present invention:
1, outstanding high temperature resistance and oxidation stability: the 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 ℃, but the long period uses under 220 ℃ of Working environments; The high temperature oxidation stability is one of main use properties of railway grease, and railway grease used and store bigger influence.The oxidation stability of railway grease is relevant with basic oil properties with the preparation grease thickener, and this product viscosifying agent can be avoided the metal catalytic effect of base oil oxidation under the high temperature, so have the good high-temperature anti-oxidative stability because of metal ion not.
2, the colloid stability and the pumping of excellence: railway grease colloid stability is to weigh a tool important indicator of a railway grease use properties and shelf characteric quality.This product viscosifying agent is an organism, with base oil good affinity is arranged, and 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 need lubricate product in the winter time and have good temperature pumping property, even this product under-30 ℃ condition, also can satisfy 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 good adhesive capacity, under 220 ℃ of Working environments, use noncoking, can not cause the slideway wearing and tearing; And water pouring loss is low; Water repelling property is good, contacting with water even mixing the back denseness with water and reduce very for a short time, can effectively get sealing function.
4, has 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 simultaneously to bear bigger impact load, the MO of the HV deep refining that this product is selected for use still can well form excellent oil film thickness under high loading; Test shows, P
BCan reach more than the 1000N P
DCan reach more than the 6000N.
5, the work-ing life of overlength: the high-temperature behavior of railway grease is meant railway grease bearing life at high temperature; Be the reflection of the comprehensive use properties of railway grease, the level of fundamental propertys such as colloid stability, mechanical stability and oxidation stability that can constitutionally reflection railway grease.This product is under 160 ℃ temperature; Life-span reaches (TP ASTM D 3336) more than 1000 hours, has good bearing working ability, has long work-ing life; Be more than 10 times of general soap base grease its work-ing life, therefore has high economic worth and use value.
