Abstract
The utility model relates to a surfacing wear resistant composite steel pipe comprising an externally-located carbon steel pipe or stainless steel tube matrix layer, wherein a high chromium carbide wear resistant layer is welded at the inner wall of the matrix layer and the surface of the high chromium carbide wear resistant layer is provided with microcracks capable of preventing the stress deformation of the steel tube matrix layer. The steel pipe disclosed by the utility model belongs to material transmission pipelines in the technical fields of mining machinery and ferrous metallurgy; and compared with conventional transmission pipelines in the market, the surfacing wear resistant composite steel pipe disclosed by the utility model has the characteristics of high wear resistant property and long service life.
Description
Technical field
The utility model relates to the material conveying pipe in mining machinery, Ferrous Metallurgy field, relate in particular to a kind of build-up wear-resistant composite steel tube, have higher wear-resisting property and the characteristics of long service life, improve the transfer efficiency and the maintenance cost that has reduced equipment of equipment.
Background technique
The build-up wear-resistant composite steel tube is the vitals of mining machinery and iron and steel metallurgical industry material conveying pipe equipment, the structure that present existing conveyance conduit adopts is the individual layer thin-wall steel tube, normally improve wear-resisting property by modified and quenching, but after standing high temperature easily lower hardness, wear-resisting property obviously weakens and the easy deformed damaged of pipeline, there is certain potential safety hazard, the transfer efficiency of complete equipment is lower, and maintenance cost is higher.
?
Summary of the invention
The technical problems to be solved in the utility model is: what provide that a kind of conveyance conduit uses has higher hardness and a higher build-up wear-resistant composite steel tube of wear-resisting property.
For addressing the above problem, the technical solution of the utility model is: the build-up wear-resistant composite steel tube, comprise and be positioned at outside carbon steel tube or Stainless Steel Tube base layer, internal layer is and the high chromium carbide wearing layer of the tight built-up welding of base layer that described high chromium carbide wearing layer surface is the microscopic crack that prevents the base layer stress deformation.
Effective effect of the present utility model is: the build-up wear-resistant composite steel tube that above-mentioned material conveying pipe is used, high chromium carbide wearing layer in carbon steel tube or a kind of higher hardness of stainless steel inside pipe wall built-up welding, high chromium carbide wearing layer surface presents the microscopic crack that can prevent the distortion of steel pipe matrix stress, because the high chromium carbide wearing layer of internal layer has the stress deformation that the microscopic crack on higher hardness and compressive strength and wearing layer surface can prevent the steel pipe matrix, so the wear-resisting property of build-up wear-resistant composite steel tube and bearing strength are improved significantly.
Description of drawings
Fig. 1 is the structural representation of build-up wear-resistant composite steel tube described in the utility model.
Fig. 2 is the sectional structure schematic representation of Fig. 1.
Among the figure: 1, steel pipe base layer, 2, high chromium carbide wearing layer, the microscopic crack on 3 high chromium carbide wearing layer surfaces.
Embodiment
Below by specific embodiment the utility model build-up wear-resistant composite steel tube is further described.
As shown in Figure 1 and Figure 2, the utility model build-up wear-resistant composite steel tube, comprise being positioned at outside steel pipe base layer 1, the inwall of steel pipe base layer 1 is the high chromium carbide wearing layer 2 of built-up welding, and the surface of described high chromium carbide wearing layer 2 is provided with the microscopic crack 3 that can prevent 1 stress deformation of steel pipe base layer.
Effective effect of the present utility model is: above-mentioned material conveying pipe build-up wear-resistant composite steel tube, at carbon steel tube or the stronger high chromium carbide wearing layer of a kind of hardness of stainless steel inside pipe wall built-up welding, high chromium carbide wearing layer surface presents the microscopic crack that can prevent the stress deformation of steel pipe base layer, because the high chromium carbide wearing layer of internal layer has the stress deformation that the microscopic crack on higher hardness and compressive strength and wearing layer surface can prevent the steel pipe matrix, so the wear-resisting property of build-up wear-resistant composite steel tube and bearing capacity are improved significantly.
