Chromium Carbide Hardfacing Welding Wear Rotor Blades

Rotor blade is mainly used for crushing hot sinter at 700~800℃ at the end of sintering machine. In order to extend the service life of single tooth roller, our company has chosen the method of reforming the metal composition at the worn part of single tooth roller. Chromium carbide overlay composite surface is adopted, and wear-resistant materials are added to the wear-resistant parts. The wear resistant alloy is welded in the worn part by surfacing repair.

 

Overview:

Chromium carbide is a hard and wear-resistant material that is ideal for protecting rotor blades in high-wear environments. 

By applying a layer of chromium carbide through welding, the rotor blades are able to withstand the abrasive forces that they are subjected to during operation.

 

The hardfacing process involves carefully preparing the surface of the rotor blades, ensuring that they are clean and free of any contaminants. 

The chromium carbide is then applied to the surface of the rotor blades using a welding process, creating a strong bond between the material and the blade.

 

Once the chromium carbide has been applied, the rotor blades are ready to be put back into operation. 

The hardfacing layer provides a protective barrier that helps to extend the lifespan of the rotor blades, reducing the need for frequent replacements and maintenance.
