Abstract
The utility model pertains to a slide transport system, relates to a horniness alloy hard wearing scale board. The utility model is made up by a working face, a wedge storage material groove and a scale board matrix, the utility model is characterized in that the working face is made up by adopting carbonization tungsten matter agglutinant horniness alloy, the working face section shape is provided with a rows of roof tiles shape, wherein the inside, outside outline is roundness or polygon; the working face the fixed way on the scale board matrix is provided with a suit shape; the working face is evenly distributed and arranged, the wedge storage material groove is formed between the two working faces. The utility model is provided with a horniness alloy coverage type, the coverage rate reaches above eighty percent of the scale board working surface, thus utmost exploit the horniness alloy materials, reduce the manufacture cost. The wedge storage material groove structure forms an efficient material cushion, to protect the scale board matrix preventing the materials brushing. Can according to the concrete use demands and scale board section situations to flexibly arrange, thus reach the best use efficiency. The manufacture craftwork is simple, useful time is long.
Description
Technical field
The utility model belongs to the slip load transfer device, relates to a kind of hard alloy abrasion-proof backing block.
Background technology
Particle bulk material by gravity transports in the mode of carrying of sliding, and to be widely used and many occasions such as metallurgy, building, harbour, this class slip load transfer device is commonly referred to slide plate, chute, slide carriage, chute etc.A resistance to abrasion that the important techniques index is the liner plate surface of slip load transfer device, it has determined the use cost and the service life of equipment.At present, tradition is used following dual mode: 1, composite plate structure, promptly on common steel plate pile-up welding hard alloy as wearing layer, this mode belongs to the mode of production of casting hard alloy, not only the mechanical strength of hard alloy is low, and because technology is limit, will inevitably produce tortoise shape crackle when built-up welding reaches certain thickness, under the scouring action of material, its hard alloy layer can come off very soon.
2, inlay the shape structure, i.e. tungsten carbide button's piece on common steel plate, dense arrangement, form hard spot on the liner plate surface, reach anti abrasive purpose, but limit because of structure, the degree of utilization of its hard alloy is low, and the hard spot layout is close more, though the resistance to abrasion performance improves, the intensity of parent can reduce greatly, under the scouring action of material, parent can be worn very soon, and causes the damage of whole liner plate.
Summary of the invention
The slug type hard alloy is because itself high hardness and high strength, has been proved to be abrasion resistant material at present, but the characteristic that its existence involves great expense, can not weld, can not process.How that hard alloy failure-free on the liner plate parent of thermal sintering is fastening, can utilize hard alloy to greatest extent with cost-cutting, can not be subjected to washing away of material by actv. protection parent again, make it to become the abrasion-proof backing block of high life.The purpose of this utility model is for overcoming the shortcoming of above-mentioned existence, a kind of hard alloy abrasion-proof backing block being provided.
The utility model content Description:
The utility model hard alloy abrasion-proof backing block, form by driving surface, wedge shape material stock groove, liner plate parent, it is characterized in that: driving surface adopts carbonized tungsten thing slug type hard alloy to make, and the driving surface section form is " row of tiles on a roof " shape, and its inside and outside profile is circle or polygon; The fixed form of driving surface on the liner plate parent is nested form; The evenly distributed layout of driving surface forms wedge shape material stock groove between two driving surfaces.
The utility model hard alloy abrasion-proof backing block is the hard alloy cover type, and its coverage rate has reached more than 80% of liner plate running surface, has utilized Hardmetal materials to greatest extent, has reduced manufacturing cost.Wedge shape material stock groove structure has formed the actv. backing strap, is not subjected to washing away of material with protection liner plate parent.Can reach best result of use according to the section situation flexible arrangement of concrete operating needs and liner plate.Have simple, the long service life of manufacturing process, reduced the characteristics of productive costs widely.
Description of drawings
Fig. 1 is a hard alloy abrasion-proof backing block structural representation
Among the figure: 1 is that driving surface, 2 is that wedge shape material stock groove, 3 is the liner plate parent
The specific embodiment
The utility model hard alloy abrasion-proof backing block is to realize like this, be described further below in conjunction with accompanying drawing, see Fig. 1, driving surface 1 adopts carbonized tungsten thing slug type hard alloy to make, the section form of driving surface 1 is " row of tiles on a roof " shape, and its inside and outside profile is circle or polygon; The fixed form of driving surface 1 on liner plate parent 3 is nested form, is the hard alloy cover type, and its coverage rate has reached more than 80% of liner plate running surface, has utilized Hardmetal materials to greatest extent, has reduced manufacturing cost.Driving surface 1 evenly distributed layout forms wedge shape material stock groove 2 between two driving surfaces, wedge shape material stock groove structure has formed the actv. backing strap, is not subjected to washing away of material with protection liner plate parent.It is big that the utility model " row of tiles on a roof " shape hard alloy abrasion-proof backing block is specially adapted to the punishment in advance amount, require liner plate that the occasion of high-wearing feature, reliable operation is arranged, as be used for the distributor chute of iron-smelter bell-less blast furnace, can be improved more than three times the service life of the existing distributor chute of blast furnace.
