Abstract
The utility model relates to a wearable alloy casting and melting elbow of two metals with the technical proposal of that: based on the prior art of casting and melting elbow with two metals comprised of an elbow and a wearable alloy layer that is cast and melted on the inner surface of the elbow, an alloy steel band or a reinforced steel bar having a trapezium section is welded on the inner surface of the elbow between the elbow and a wearable layer, and the wearable alloy layer cast and melted on the inner surface wraps the alloy steel band or reinforced steel bar. The utility model has the advantages of that the strength of connection between the steel band or reinforced steel bar welded on the inner surface of the elbow and the elbow is strong.; at the same time, the wearable alloy layer wraps the alloy steel band or reinforced steel bar which form an integer; thereby the strength of the connection between the wearable alloy layer and the elbow is increased, and the phenomena of skin branch and dropping during the utilization of the elbow with two metals is avoided; therefore, the utility model can be applied as the elbow on the tubes of coal powder transferring and clinker discharge in the thermal power trade to ensure a safe and normal production.
Description
Technical field
The utility model belongs to
Background technique
In order under the situation that keeps the binding performance that is welded to each other of pipe element, comprehensive mechanical strength and lower cost, to improve the scratch-resistant performance or the decay resistance of inner surface of pipeline, occurred some successively and adhered to the wearing layer of different materials or composite pipe, the composite elbow of anticorrosion layer at original pipe element internal surface.As adhere to anti-corrosion plastics pipe element, adhere to the pipe element of wear-resistant alloy layer.In elbow, adhere to the alloy wear-resisting layer with seamless steel pipe mechanism, usually adopt be with the abrasion resistance alloy founding on elbow interior wall.Because the materials flow that pipeline endoparticle material is formed is forced to change flow direction in the elbow position, formation is to the impact of elbow internal surface, make the elbow internal surface be subjected to bigger active force, the inside and outside two-layer adhesive strength of the bimetal elbow that aforementioned preparation process obtains is lower, often string skin, obscission that the wearing layer in the elbow occurs, what influence was produced normally carries out.
Summary of the invention
The purpose of this utility model provides the molten elbow of a kind of bimetal wear resistant alloy casting, overcomes these type of elbow above shortcomings in the prior art.
The technical solution of the utility model is: comprise that existing elbow and casting melt on the basis at the molten elbow of bimetal casting of the alloy wear-resisting layer of elbow internal surface, increasing between elbow and wearing layer has trapezoid cross section Alloyed Steel Strip or the reinforcing bar that is welded on the elbow internal surface, and founding is surrounded Alloyed Steel Strip or reinforcing bar at the alloy wear-resisting layer of elbow internal surface.
Good effect of the present utility model is: owing to be welded on the steel band of elbow internal surface or reinforcing bar and elbow very high join strength is arranged.The alloy wear-resisting layer is wrapped in Alloyed Steel Strip or reinforcing bar simultaneously, forms whole.The adhesive strength of alloy wear-resisting layer and elbow is strengthened, eliminated the phenomenon of adhering to wearing layer string skin, coming off during the bimetal elbow uses, be applicable to the powder of delivering coal in the thermoelectricity industry, go out the elbow on the lime-ash pipeline, can guarantee production safety, normally carry out.
Description of drawings
Fig. 1 looks sectional view for the utility model master.
Fig. 2 is an elbow cross-sectional view of the present utility model.
Embodiment.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
By existing technology material is that Q235 or 16Mn seamless steel pipe are made the elbow 1 in the accompanying drawing, and selecting thickness is 2/3 of definite wearing layer thickness, and width is the trapezoid cross section Alloyed Steel Strip 2 of 3 times of self width.The ratio on two bases, steel band trapezoid cross section is 4/5-3/5.Be interrupted welding alloy steel band 2 along elbow 1 axis at internal surface.The short base of steel band is towards the elbow internal surface.Steel band also can be in elbow internal surface spiral or oblique layout, but can increase the integrated artistic difficulty.The fusion length of steel band on elbow is no less than 1/4 of steel band length overall.4 Alloyed Steel Strips of the equidistant welding of elbow that diameter 500mm is following.The elbow that diameter 500mm is above, the corresponding increase of the quantity of used steel band.Manufacture and be welded with the polystyrene mold that steel band elbow inner chamber matches by the thickness of the wearing layer of setting, mold is placed in the elbow,, form wearing layer 3, promptly finish of the present utility model manufacturing by existing lost foam casting process casting High Chrome Alloy Steel.Elbow between the utility model application diameter 133-2000mm.
Claims (1)
1, the molten elbow of bimetal wear resistant alloy casting, comprise elbow, cast and melt at elbow internal surface De Gao Chrome alloy wear-resisting layer, it is characterized in that: the Alloyed Steel Strip or the reinforcing bar that are welded on the trapezoid cross section on the elbow are arranged between elbow and wearing layer, and the high-chromium alloy wearing layer surrounds Alloyed Steel Strip or reinforcing bar.
