Products Metallurgy bimetallic wear resistant pipe is nearly two decades of rapid development of a foreign project pipeline, varieties, many functions, superior performance. Cooperation with well-known institutions to develop wear-resistant bimetallic tube metallurgy, centrifugal casting by bimetal coating material can be combined with metallurgical substrate interface and excellent quality, widely used in mining, power, chemical, and metallurgical coal industry. Bi-metal wear and metallurgical process characteristics in the production process pipe straight centrifugal casting technology, which is a fusion of the two metals are formed in the liquid state, to achieve a true metallurgical bonding purposes, combined interlaminar shear strength than the body metal, the full realization of the grassroots and mechanical wear layer complementary; elbows, tees, reducers and other fittings using vacuum suction casting EPC composite technology, advanced its technology to effectively solve complex problems can not bend, bend and other various special-shaped pipe can do the whole complex, does not change the material flow in the bend of the track, greatly reduce material handling resistance. In the material of choice centrifuge tube outer wall carbon steel pipe to ensure that the wear resistance with high mechanical strength and impact resistance; lining wear layer to choose our own research and development of anti-wear steel series, the steel major Add a Cr-Ni-Mo-Cu-RE alloy, after quenching and tempering heat treatment process, so that the steel has both a strong wear and corrosion resistance properties, have high mechanical strength and impact resistance. My company's entire process is a national initiative to fill the gaps in the industrial pipeline corrosion resistant, and has reached the international advanced level, has been widely used in mining, metallurgy, coal, electric power industry, is an ideal wear-resistant pipes . Centrifugal casting characteristics (1) centrifugal casting process is so far above the molten steel casting several times under normal gravity conditions of solidification molding, cast solved the problem of loose tube inside, high density metal, its row slag, good exhaust effect. High (2) centrifugal casting dimensional accuracy, uniform thickness, provide a favorable environment to ensure the accuracy of the size of the subsequent processing of the product. (3) centrifugal casting process for small-volume, multi-species multi-standard, high-quality, high value-added steel pipe production, with high flexibility. Application specific products industry and product content: Composite Wear straight pipe, composite wear-resistant elbow, composite three, four and composite diameter pipe fittings such as the power industry: transport coal, transport cinder composite wear-straight, bend tubes and other kinds of special composite wear-resistant pipe; mine system: filling underground engineering wearable straight pipe, pipe and other various Yixingguan pieces; concentrator: tailings pipeline, concentrator complex internal processes in the slurry transport wearable straight, elbow, tee, cross and other various shaped composite overcurrent pipe; coal industry: long-distance transport of pulverized coal in a straight pipe, elbow, tee, cross; washery coal washing process in straight pipe, elbow, tee, cross and other various shaped composite overcurrent fittings; smelting industry: mineral and solvent delivery composite straight, bend and and other kinds of special wear-resistant composite pipes. Since the mechanical properties of metallurgical bonding interface between the substrate and the cladding layer has a sufficient bonding strength, usually reaches more than 300Mpa; composite can enhance the strength or toughness of the corresponding base, to achieve mechanical properties complementarity; choose different properties of composite materials, to obtain excellent resistance to corrosion, or the ability to wear harsh environments, to extend the service life of steel.
