Customized hardware elevator bracket-guide rail bracket

The surface treatment process during the manufacturing process of elevator guide rail brackets includes the following key steps:
1. Cleaning: First, clean the elevator guide rails to remove impurities and oil on the surface to prepare for subsequent surface treatment.
2. Laser cladding: Use a specific ratio of cemented carbide powder (including titanium carbide powder, tungsten carbide powder, molybdenum powder, nickel powder and cobalt powder) for laser cladding to enhance the hardness and wear resistance of the elevator guide rail surface .
3. Nitriding treatment: After laser cladding, the elevator guide rails are surface nitrided to improve their hardness and wear resistance. This step is completed in a hot isostatic pressing furnace, using nitrogen as the working gas, and the working pressure It is 80MPa, and the nitriding time is about 80-120 minutes.
4. Heat treatment: The nitrided elevator guide rail is heat treated at a temperature of 440-480 degrees Celsius to further optimize its surface properties, and the heat preservation time is 1-2 hours.
In addition to the main steps mentioned above, the surface treatment of elevator guide rail brackets may also include the following auxiliary measures:
Coating - Plating: Improve the durability and corrosion resistance of the guide rail by adding wear-resistant coatings, anti-corrosion coatings or other special coatings.
Anodizing: Suitable for aluminum alloy guide rails. Anodizing improves surface hardness and corrosion resistance.
Polishing: Improves the smoothness of the guide rail surface, reduces friction and wear, and is often used in high-precision and low-friction applications.
