In the oil exploration industry, as the drilling pump pressure continues to increase, the erosion failure problem of oil drilling steel drill bits is becoming more and more serious. The working conditions of the drill bits are becoming more and more complex and harsh, and higher and higher requirements are placed on the wear-resistant layer of the drill bit cladding. At present, the wear-resistant cladding layer for oil drilling tools PDC drill bits mainly relies on imported welding ropes. The carbide wear-resistant flexible Welding Rope products developed by Luoyang Golden Egret has very excellent corrosion resistance and wear resistance, and high impact resistance, and have been successfully used in this field. Luoyang Golden Egret tungsten carbide wear-resistant flexible welding rope is made by extruding and coating a mixture of nickel-based alloy powder and irregular cast tungsten carbide particles, spherical cast tungsten carbide particles, cemented carbide balls, diamond particles, etc. on the surface of the nickel core. The product uses nickel-based alloy as the bonding phase and tungsten carbide as the hard phase. The product performance characteristics are as follows:tungsten carbide wear-resistant flexible welding rope surfacing layer diagram
Hard phase distribution: The hard phase is evenly distributed in the cladding layer, which makes the cladding layer have good corrosion resistance, wear resistance and impact resistance, and the performance reaches or even exceeds the standards of imported products.
The wear resistance test adopts ASTM G65 standard. The wear resistance of CTC flexible welding rope products is equivalent to that of similar products of imported brands.
Application:
Oil and gas drilling: stabilizer blades, PDC drill bits, etc.
Foundry and steel industry: sand mixer scrapers, press guide rails, etc.
Chemical industry: mixer blades and screws, cylinder scrapers, press jackets and casings, etc.
Method of Application:Oxyacetylene flame surfacing has the advantages of simple equipment, simple and flexible operation process, low cost, low dilution rate, and smooth and beautiful surface.
