Description
Technical field
The present invention relates to a kind of roasting kiln wheel belt special lube and its preparation method, belong to equipment maintenance field.
Background technology
Roasting kiln belongs to chemical metallurgy rotary kiln, is widely used in the poor iron ore magnetic roasting of metallurgy industry Steel Plant, magnesium-smelting silicothermic process, chromium, josephinite oxidizing roasting etc., and load is big, and temperature height, working condition is severe.
Cylinder of rotary kiln is sectional welding, wheel belt is suit, so the internal diameter size of wheel belt need to be designed to bigger than the external diameter of cylinder, after such installation in position, there is gap between wheel belt internal diameter and cylinder (containing backing plate) external diameter because of diameter difference, circumferential motion lower shell can produce " displacement of relatively rolling " phenomenon with wheel belt because girth is different. ideally, when rotary kiln runs well, the radial thermal expansion amount of cylinder can just offset the gap between wheel belt and backing plate, and reality is, rotary kiln is a dynamic process when operating, because fluctuation of operating conditions, or the differences such as cylinder rigidity difference, gap between each shelves cylinder and wheel belt fails to offset with cylinder radial thermal expansion amount, this gap outwardness, even can strengthen gradually along with the growth of rotary kiln runtime, " displacement of relatively rolling " phenomenon can be all the more obvious, if lubricating improper between wheel belt and cylinder or not lubricating, rolling displacement will be occurred abnormal, stuck or skidding can be there is in contact surface, this phenomenon can cause the abnormal friction between backing plate and wheel belt, shake when cylinder operates, aggravation cylinder of rotary kiln distortion, bring out the breakage of resistance to material in kiln body and come off, thus cause rotary kiln stop production to overhaul, the windfall losses such as cylinder life-span minimizing.
For the moment of friction reduced between wheel belt and backing plate, reduce or eliminate " rolling displacement " abnormal, it is necessary to have a kind of special lube to protect the contact surface between wheel belt and backing plate.
Rotary kiln tyre backing plate lubrication is a kind of novel lubricating theory, because until recent years, the producer that the hazardness of wheel belt " displacement of relatively rolling " is just got more and more payes attention to, and the high temperature wheel belt oil that can buy on market is substantially by the monopolization of external lubricating oil brand as (Fu Si, doubly can, Ke Lubo, rub magnitude), a domestic line brand is (such as Great Wall, the Kunlun etc.) there is not high temperature wheel belt oil product board to release up to now yet, even and foreign brand name, strict, still not having a is really special high temperature wheel belt oil. With existing compare conventional doubly can BechemBERULUBVPN13 lubricating oil, this lubricating oil only is used to lubricate the bolt under fully loaded transportation condition, socket or stainless steel bayonet socket connection etc. at first, prevents bolt and nut stuck. Perhaps more should being called the anti-card oil of composite bolt, this is also the reason that this oil additive contains superfine copper powder particle, and copper powder can form solid metal film in the junction of bolt and equipment, can effectively prevent stuck and oxidation.
In addition, the existing wheel belt oil being applicable to wheel belt backing plate lubrication, generally expensive, unit price is generally not less than 200 yuan/kilogram, for the star RINGLUBE600M wheel belt oil that rubs, purchasing price reaches 5700 yuan/barrel (25kg dresses), and doubly can BechemBERULUBVPN13, purchasing price is then 2600 yuan of/barrel (10Kg dress) left and right.
Summary of the invention
It is an object of the invention to solve above-mentioned deficiency, it is provided that one can be allocated at random according to different operating mode, has handiness and economy concurrently, energy-saving and cost-reducing, cost-saving roasting kiln wheel belt special lube and its preparation method.
The present invention is achieved through the following technical solutions.
The present invention is a kind of roasting kiln wheel belt special lube, it is oil based on heavy-duty industry enclosed gear oil, solid additive is served as with Graphite Powder 99 and molybdenum disulphide powder, mix even rear stirring according to the fixed proportion of weight percent 7:2:1 to be deployed into, wherein, described heavy-duty industry enclosed gear oil selects model to be L-ckd220 according to according to viscosity index, L-ckd320, one in L-ckd460 or L-ckd680, Graphite Powder 99 selects model to be 300 orders according to fineness, one in 500 orders or 1500 orders, molybdenum disulphide powder selects model to be that 2000 objects are a kind of according to fineness.
Preferably, described heavy-duty industry enclosed gear oil selects model to be the one of L-ckd220 according to according to viscosity index, and Graphite Powder 99 selects model to be that 1500 objects are a kind of according to fineness, and molybdenum disulphide powder selects model to be that 2000 objects are a kind of according to fineness.
