Abstract
The utility model discloses a blast furnace slag treatment granulation wheel blade which comprises a connection end and a blade body. The connection end is arranged at one end and on the outer side of the blade body, at least one protruded tooth is arranged on an end face of the inner side of the blade body, and the protruded tooth is in a semicircle shape is integrally poured with the blade or fixed on the blade body through a bolt. The blast furnace slag treatment granulation wheel blade improves wear resistance of the granulation wheel blade in structure, improves wear resistance, heat resistance and toughness of the granulation wheel blade in materials, and can work on the work conditions of shock heating, shock cooling, furnace slag friction and partial explosion. Compared with traditional high-chromium iron, the service life of the blast furnace slag treatment granulation wheel blade is prolonged by 3 to 5 times.
Description
Technical field
The utility model relates to a kind of blade, is specifically related to a kind of blast furnace slag and handles the granulation impeller blade.
Background technology
The granulated blast-furnace residues processing technique is as a kind of imported technology, and each big steel manufacturing enterprise is used widely in the whole nation.In the blast furnace slag treatment system, the granulation wheel plays keying action, the fragmentation of slag, granulation, and the reasonable drop point of grain slag, distribution are taken turns by granulation entirely and are accomplished.And the granulation impeller blade is the major critical component of granulation wheel; It receives the effect of high-temperature slag and cryogenic impact (slag) water at work; Bear frequent rapid heat cycle; And the blast that partial molten iron can produce small area in the slag when running into flushing cinder water, granulation impeller blade surface is produced than the macro-energy impact, Working environment is very abominable.Existing granulation impeller blade is generally thin lamellar body; Its material adopts heat resisting iron or rich chromium cast iron; When blade bear frequent rapid heat cycle, than the flow of the impact blast of macro-energy and slag become big, when flow velocity is accelerated; Will cause that the granulation impeller blade breaks, slagging scorification, scaling loss and come off, cause the granulation wheel to be scrapped too early.The granulation wheel is keeped in repair, changed to the slag treatment system regularly, both influenced the blast furnace ordinary production, increased production cost again.
Summary of the invention
The purpose of the utility model is to provide a kind of being applicable in rapid heating and cooling, slag friction, confined explosion to impact under the operating mode to above-mentioned deficiency, has well wear-resisting, heat-resisting, impact-resistant blast furnace slag and handles the granulation impeller blade.
The purpose of the utility model is achieved in that a kind of blast furnace slag processing granulation impeller blade, comprises coupling end and blade body, and coupling end is arranged on an end and the outside of blade body, it is characterized in that: the inboard end face of blade body is provided with at least one double wedge.
The length of said double wedge equates with the width of blade body, lacks 20%-25% near the length of blade body right-hand member double wedge than the width of blade body.
Said double wedge is semicircle, is cast into one with blade body or through being bolted on the blade body.
The material of said blade body and double wedge is low alloy steel.
Compared with prior art, the utility model has the advantages that:
1, improved the wear resistance of granulation wheel blade lamellar body from structure.The utility model has not only increased the thickness of blade body, and has increased several double wedges at the medial surface of blade body, whole intensity and the wear resistance that has improved granulation wheel blade lamellar body on the structure.
2, wear resistance, thermotolerance and the toughness of granulation wheel blade lamellar body have been improved from material.The utility model blade body material adopts the low alloy steel integral cast, contains alloying elements such as chromium, nickel and rare earth in the material, thereby has improved wear resistance, thermotolerance and the toughness of cast steel material, and have good comprehensive use properties.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the plan structure synoptic diagram of Fig. 1.
Among the figure: coupling end 1 and 3, blade body 2, double wedge 21.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Referring to Fig. 1, a kind of blast furnace slag is handled blade, comprises coupling end 1,3 and blade body 2, double wedge 21; Coupling end 1 is arranged on the left end of blade body 2; Coupling end 3 is arranged on the outside of blade body 2, and blade body 2 inboard end faces are provided with at least one double wedge 21, and present embodiment is provided with three double wedges 21.The length of double wedge 21 equates with the width of blade body 2, and shorter by 20%-25% than the width of blade body 2 near the length of the double wedge 21 of blade body 2 right-hand members, present embodiment is short by 20%, the resistance when reducing blade body 2 rotations.Double wedge 21 is semicircle, with blade body 2 integral casts be one.Also can double wedge 21 and blade body 2 be cast respectively, double wedge 21 is convenient to change, to reduce maintenance cost after double wedge 21 wearing and tearing through being bolted on the blade body 2.
The material of blade body 2 and double wedge 21 all adopts low alloy steel, and the casting back obtains tempered martensite through low-temperaturetempering behind shrend or the oil quenching.
The utility model is simple in structure, and long service life is worked under rapid heating and cooling, slag friction, confined explosion's impact operating mode, compares with traditional high-chromium iron its work-ing life and can improve 3-5 doubly.
