Laser cladding Co-based alloy powder for conductor roll

InactiveCN101187022ASolve repair problemsImprove performanceMetallic material coating processesChemical compositionAlloy substrate

Provided is cobalt-based alloy powder for laser cladding electricity conducting roller, the weight percentages of the chemical components of the material are that Cr is 24-30%, W is 6-10%, Mo is 3-6%, Ni takes 6-12%, Fe holds 2-10%, Mn is 0.5-2%, Si holds 0.2-2%, V is 0.1-0.6%, B takes 0.3-1.5%, C holds 0.5-2.5%, Y2O3 is 0-0.5%, Hf takes 0-0.5%, La2O3 holds 0-0.5%, Ce is 0-0.5%, and the rest is Co. The invention has the advantages that with multiple strengthened methods, the alloy substrate is strengthened and the crystal boundary quality is improved, which enables the alloy to achieve perfect combination property, thereby achieving medium rigidity and relatively high intensity of the alloy, simultaneously forming self-fluxing alloy and reducing alloy melting point, and increasing properties of oxidation resistance, abrasion resistance, corrosion resistance, and certain electricity conduction.

Gradient alloy material and method for laser strengthening of copper plate of crystallizer of continuous casting machine

InactiveCN103805813AImprove toughnessStrong metallurgical bondMetallic material coating processesWear resistantHigh-temperature corrosion

The invention provides a gradient alloy material and method for laser strengthening of a copper plate of a crystallizer of a continuous casting machine. The method comprises the following steps: enabling transition of a nickel-based alloy material and a substrate on the working surface of a narrow chromium zirconium copper plate of the crystallizer by a laser cladding technology; and then cladding a special cobalt-based alloy material on the nickel-based alloy transition layer to form a new gradient alloy layer on the working surface of the narrow chromium zirconium copper plate of the crystallizer, wherein the gradient alloy layer is resistant to high temperature corrosion and wear resistant and is of an ultrafine and high-toughness metallographic structure. The cobalt-based alloy material is the novel cobalt-based alloy material prepared from the cobalt-based alloy by adding Hf, B and Si elements on the basis of satellite, and then properly lowering down the melting point of the alloy. Compared with the prior art, the gradient alloy material and method have the beneficial effects that the resistance to high-temperature corrosion and the wear resistance of the working surface of the narrow plate of the crystallizer are improved, the laser repair and reproduction of a crystallizer out of work are realized, and the use performance of the crystallizer can also be recovered and improved; in addition, the problem due to the repair of a chromium zirconium copper crystallizer out of work can be effectively solved; the quality of a casting blank is improved; the casting cost of steel per ton can be decreased.

Method for repairing converter supporting ring

InactiveCN104439877AFix minor issuesSafe and reliable connectionEngineeringSpare part

The invention relates to a method for repairing a converter supporting ring. The method comprises the following steps that (1) an old converter supporting ring is disassembled, and a transmission side trunnion and a non-transmission side trunnion assembly are obtained; (2) a tangential key on the transmission side trunnion is removed; (3) a large gear on the transmission side trunnion is dismounted; (4) new supporting ring fan-shaped sections are designed and made optimally; (5) two trunnion assemblies are repaired and the ends of the trunnion are sealed; (6) the two trunnion assemblies and the two fan-shaped sections are assembled on site; (7) the two trunnion assemblies and the two fan-shaped sections are welded and annealed on site. The method is used for repairing the converter supporting ring, greatly shortens the manufacturing period of the supporting ring, guarantees repairing quality and saves a great number of spare part expenses for enterprises.

Structure type impeller breaker

InactiveCN101837312ANo prone castingNo processingGrain treatmentsImpellerWear resistant

The invention relates to a structure type impeller breaker, comprising a rotor; the structure type impeller breaker is characterized in that: the rotor comprises a bottom plate (1), a ring-shaped top plate (2), a material dividing cone (3) and a plurality of connection plates (4); the material dividing cone (3) is fixed on the bottom plate (1) by a fastening piece, the connection plates (4) are arranged between the bottom plate (1) and the ring-shaped top plate (2), and a material blowing opening (5) is formed between the adjacent connection plates (4); a discharging outlet protecting ring (6) is arranged at the center of the ring-shaped top plate (2), an upper protecting ring (7) is welded at the outer ring of the ring-shaped top plate (2), a lower protecting ring (8) is welded at the outer ring of the bottom plate (1), and a wear resistant material layer is arranged on the outer surface of the connection plate (4); a replaceable injection orifice lining plate (9) is arranged at the same sides of all material blowing openings (5), and an upper padding plate (13) and a lower padding plate (14) are respectively welded on the upper and lower surfaces of the material blowing opening (5). The structure type impeller breaker radically solves the difficult problem that a rotor wear-out part is hard to be used repeatedly after being worn out, a great amount of raw material can be saved and the cost is reduced.
