Description
Technical field
The present invention relates to a kind of carbon dust bend pipe structure, especially relate to a kind of carbon dust bend pipe structure for carbon-oxygen gun, belong to metallurgical production equipment duplicate design and manufacturing technology field.The invention still further relates to a kind of manufacture method manufacturing described carbon dust bend pipe structure.
Background technology
Carbon-oxygen gun is the visual plant in the middle of electric arc furnace smelting, and how efficiency utilization then directly affects is smelted rhythm, reduces production cost.Be blown in electric arc furnace at the carbon dust of smelting process high speed flowing by the carbon dust bend pipe of carbon-oxygen gun, at high temperature the oxonium ion of replacing in molten steel reaches the object of smelting.Carbon dust is being blown in the process of electric arc furnace at a high speed, owing to continuing in granular carbon dust described bend pipe, rubbing for a long time, is being easy to the tube wall of described carbon dust bend pipe is bored a hole because of wearing and tearing, especially all the more so at the turning of carbon dust bend pipe.Just can wear and tear a bend pipe for usual 24 hours, and after the tube wall of bend pipe is worn perforation, if not instantaneously changing, not only cause four of carbon dust loosely to spray, waste resource, affects service efficiency, also there is great potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is: provide one to extend using period, and reduces the carbon dust bend pipe structure for carbon-oxygen gun of production cost.Present invention also offers a kind of manufacture method manufacturing described carbon dust bend pipe structure.
For solving the problems of the technologies described above adopted technical scheme being: a kind of carbon dust bend pipe structure for carbon-oxygen gun, comprising S type carbon dust elbow body, the inner side-wall of described S type carbon dust elbow body is provided with wear-resistant components.
Further, described wear-resistant components is be coated in the wearing layer on described S type carbon dust elbow body inner side-wall.
The optimal way of such scheme is, described wearing layer is be plated on the ceramic layer on described S type carbon dust elbow body inner side-wall.
Further, the thickness being plated on the ceramic layer on the inner side-wall of described S type carbon dust elbow body bending place is greater than the thickness of the ceramic layer being plated on this other position of S type carbon dust elbow body.
Further, also weld at the two ends of described S type carbon dust elbow body and be associated with joint nut.
For the manufacture of a manufacture method for described carbon dust bend pipe structure, comprise the following steps,
A, blanking bend tube, according to arranging drawing blanking, be then bent into the S type carbon dust elbow material that drawing specifies;
B, coated with wear resistant layer, coated with wear resistant ceramic layer on the inner side-wall of the S type carbon dust elbow material obtained in step a;
C, be welded to connect nut, first joint nut is assembled to by drawing the end that plating completes the described S type carbon dust elbow body of wear-resistant ceramic layer, then described S type carbon dust elbow body is placed in water coolant, the a bit of described S type carbon dust elbow body only exposed described joint nut and be connected with this joint nut, then by as a whole for the welding edges of described joint nut and described S type carbon dust elbow body, then the described joint nut of another end of field weld is in accordance with the law reversed end for end, complete the manufacture work of the carbon dust bend pipe described in.
Further, in step a, when the S type carbon dust elbow material described in bending, tube-bending machine machinery is adopted to bend.
Further, in step c, described water coolant is anti-oxidation mixing solutions; The welding process adopted during welding is CO
2shielded welding.
The invention has the beneficial effects as follows: by adopting described working method, first prepare S type carbon dust elbow material, then plating one deck wear-resistant ceramic layer on the inner side tube wall of described S type carbon dust elbow material, is finally welded to connect a joint nut respectively at the two ends of described S type carbon dust elbow material.Because on the inner side tube wall of described S type carbon dust bend pipe, plating has the wear-resistant ceramic layer described in one deck, especially tie thicker mutually at the wear-resistant ceramic layer of the turning point plating of described S type carbon dust bend pipe, like this, when swiftly flowing particulate state carbon dust is more fast with described S type carbon dust bend pipe pipe friction, first rub with described wear-resistant ceramic layer, thus effectively can improve the wear resistance of described S type carbon dust bend pipe, extend its work-ing life, and then reach the object reducing production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention for the carbon dust bend pipe structure of carbon-oxygen gun.
Be labeled as in figure: S type carbon dust elbow body 1, wearing layer 2, joint nut 3.
Embodiment
Be that one provided by the invention can extend using period as shown in Figure 1, reduce the carbon dust bend pipe structure for carbon-oxygen gun of production cost.Described carbon dust bend pipe structure comprises S type carbon dust elbow body 1, and the inner side-wall of described S type carbon dust elbow body 1 is provided with wear-resistant components.Described wear-resistant components can be the hard material layer inlayed on the inner side-wall of described S type carbon dust elbow body 1, also can be brushing wear-resistant paint layer on the inner side-wall of described S type carbon dust elbow body 1, can also be plated on described S type carbon dust elbow body 1 inner side-wall on hard metal high-abrasive material.According to manufacturing cost, manufacture process requirement, conveniently manufacture, to reduce manufacturing cost, then combine the situation of the carbon dust used, the wearing layer 2 described in the application is for being plated on the ceramic layer on described S type carbon dust elbow body 1 inner side-wall; And the thickness being plated on the ceramic layer on the inner side-wall of described S type carbon dust elbow body 1 bending place is greater than the thickness of the ceramic layer being plated on this other position of S type carbon dust elbow body 1.
