Zhengzhou Lijia has developed the spraying process and equipment for the inner hole of tungsten carbide with a diameter of more than 100mm. As the core of the supersonic flame inner hole spraying equipment, Lijia company uses HV-80D type kerosene supersonic flame inner hole spraying gun.
Zhengzhou Lijia has developed the spraying process and equipment for the inner hole of tungsten carbide with a diameter of more than 100mm. As the core of the supersonic flame inner hole spraying equipment, Lijia company uses HV-80D type kerosene supersonic flame inner hole spraying gun. The inner hole spray gun adopts the global original design structure, has obtained the national invention patent, patent number: X and continuous design of structural innovation and optimization, the spray gun is today in the world, only using fuel and oxygen combustion of the minimum diameter of supersonic spray gun, gun front end diameter is only 80mm, can be deep within 100mm of the narrow space for spraying operations. At present, it has been successfully used in a variety of industries for small space spraying.
The technology is mainly used for inner hole, hydraulic parts, cylinder, valve body, the compressor bore, shell lumen, inside the container, eight hole and internal condition, in the narrow space can be realized by this technology in the inner diameter 100 mm above the wall coating cemented carbide coating, the coating hardness, vickers hardness above HV1100, wear-resisting, anti-corrosive, high temperature resistance, and other functions, At present, Zhengzhou Lijia is actively researching and developing for smaller inner hole spraying, and plans to develop the hard alloy spraying technology within the inner diameter of 80mm in the second half of this year. At present, our company undertakes a large number of inner hole tungsten carbide spraying business, welcome friends to visit.
