Tungsten carbide coated mirror dryer

Work piece name: Paper drying cylinder

Manufacturing process: supersonic spraying

Workpiece size: diameter 2500*2000

The mirror dryer uses thermal spraying technology to spray a tungsten carbide reinforced coating on its surface, and then grinds it. The resulting surface reinforced coating has good anti-corrosion, wear resistance, and high temperature resistance.

The papermaking dryer refers to the machine used by the papermaking machinery to continuously feed the paper blank after the pulp is formed into the dryer. Due to the high temperature and pressure it endures during operation, the dryer is prone to wear and high-temperature corrosion. For a long time, Damage will lead to a decrease in paper quality and affect production.

The tungsten carbide coated mirror drying cylinder prepared by thermal spraying technology can effectively enhance the strength of the drying cylinder surface.

Tungsten carbide has relatively high hardness, is a good conductor of electricity and heat, and has good chemical stability; the tungsten carbide coating prepared by thermal spraying technology has a dense coating, high bonding strength, high hardness, small porosity, and The material has a low degree of oxidation, which can effectively extend the service life of the dryer.
