Abstract
The utility model relates to a rotary kiln carrier roller, particularly to a rotary kiln component, which belongs to the field of mechanical components. The rotary kiln carrier roller comprises a roller carrier shaft and is characterized in that an adhering layer and a wear-resistant layer are arranged sequentially in an inside-outside order on the peripheral wall of the roller carrier shaft. The adhering layer and the wear-resistant layer are arranged on the peripheral wall of the roller carrier shaft, wherein the wear-resistant layer is fixedly adhered to the peripheral wall base material through the adhering layer, and therefore the wear-resistant layer is not easy to pell off and is wear-resistant, and the service life of the components can be effectively prolonged.
Description
Technical field
The utility model belongs to the component of machine field, is specifically related to a kind of rotary kiln parts.
Background technology
The periphery wall of rotary kiln carrying roller is as working face in industrial production, its work under bad environment of living in, and very easily wearing and tearing are when serious even can influence the transmission transportation system paralysis of integral device.Roller carrier shaft mostly is single base material of planting and makes, and the wearing and tearing that long-time high strength operation causes are difficult to repair, and generally needs to change whole parts, and have only 2～3 months the service life of common carrying roller.If adopt the high-strength abrasion-proof material to make whole rotary kiln carrying roller, can prolong its service life, yet not only processing difficulties and cost of manufacture are high like this, lose more than gain.If common coating is set on working face, itself and base material bonding effect are poor, easily peel off, and be impracticable.Therefore, the rotary kiln carrying roller of design the wear-resistant and economic saving of a kind of working face, easily processing has been the task of top priority.
The utility model content
The technical problem that the utility model solved is: designed a kind of rotary kiln carrying roller, working face is wear-resistant, long service life.
The technical scheme that its technical problem that will solve the utility model adopts is: design a kind of rotary kiln carrying roller, comprise roller carrier shaft, it is characterized in that being provided with in proper order from inside to outside adhesive layer and wearing layer on the periphery wall of roller carrier shaft.
A kind of rotary kiln carrying roller described in the utility model, the periphery wall that it is characterized in that roller carrier shaft is a scored surface.Adhesive layer is the aluminium-based alloyed powder sprayed coating.Wearing layer is a nickel tungsten powder sprayed coating.
The beneficial effect that the utility model had is:
1. the utility model is provided with adhesive layer and wearing layer on the roller carrier shaft periphery wall, and wearing layer passes through the adhesive layer strong bonded on the periphery wall base material, and is incrust and wear-resistant, can effectively prolong the service life of parts.
2. roller carrier shaft periphery wall is a scored surface, can make adhesive layer more tight with combining of body base material.
3. adhesive layer is the aluminium-based alloyed powder sprayed coating, and wearing layer is a nickel tungsten powder sprayed coating, and make process operation easy and meet the aspect speciality and require: aluminium-based alloyed powder sprayed coating quality is softer, and adhesive force is good, and bonding effect is good; Nickel tungsten powder sprayed coating quality is hard, wear-resisting anti-damage.
4. the utility model is reasonable in design, and cost of manufacture is low, suitable penetration and promotion and industrialization volume production.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion partial structurtes enlarged drawing of Fig. 1;
Among the figure: 1. roller carrier shaft, 2. wearing layer, 3. adhesive layer.
The specific embodiment
A kind of rotary kiln carrying roller described in the utility model, order is provided with adhesive layer 3 and wearing layer 2 from inside to outside on the periphery wall of roller carrier shaft 1, and wearing layer 2 passes through adhesive layer 3 strong bonded on inwall, and is incrust and wear-resistant.The periphery wall of roller carrier shaft 1 is a scored surface, can make adhesive layer 3 more tight with combining of roller carrier shaft base material.Adhesive layer 3 is the aluminium-based alloyed powder sprayed coating, and wearing layer 2 is a nickel tungsten powder sprayed coating, and make process operation easy and meet the aspect speciality and require: aluminium-based alloyed powder sprayed coating quality is softer, and adhesive force is good, and bonding effect is good; Nickel tungsten powder sprayed coating quality is hard, wear-resisting anti-damage.The utility model can utilize the rotary kiln carrying roller of scrapping of excessive wear to process, the not only economic development of saving but also helping recycling economy.Its specific process is as follows:
1) cleans the roller carrier shaft 1 of scrapping the rotary kiln carrying roller with metal cleaner;
2) roller carrier shaft 1 is contained on the lathe and centering, car removes the surface fatigue layer;
3) use oxygen, acetylene with roller carrier shaft 1 first preheating, temperature is at 60 ℃--about 100 ℃;
4) plucking is with alligatoring roller carrier shaft 1 surface, through the surface ability and the combination of coating generation favorable mechanical of roughening treatment;
5) spraying adhesive layer 3, adhesive layer 3 adopts aluminium-based alloyed powder, and temperature is at 100 ℃--and 150 ℃, coating is wanted evenly to increase adhesion;
6) the spraying abrasion-proof layer 2, and wearing layer 2 adopts the nickel tungsten powder, and temperature is no more than 150 ℃, and required size stays 0.25mm-0.35mm mill amount;
7) after the spraying, be normal temperature but part must naturally cool to processing temperature;
8) going up grinding machine is milled to required size and gets final product.
Claims (4)
1. a rotary kiln carrying roller comprises roller carrier shaft, it is characterized in that being provided with in proper order from inside to outside on the periphery wall of roller carrier shaft adhesive layer and wearing layer.
2. a kind of rotary kiln carrying roller according to claim 1, the periphery wall that it is characterized in that roller carrier shaft is a scored surface.
3. a kind of rotary kiln carrying roller according to claim 1 and 2 is characterized in that adhesive layer is the aluminium-based alloyed powder sprayed coating.
4. a kind of rotary kiln carrying roller according to claim 1 and 2 is characterized in that wearing layer is a nickel tungsten powder sprayed coating.
