Calender steel rod damaged choose supersonic spray tungsten carbide

Improve wear resistance

Tungsten carbide has very high hardness and wear resistance. Supersonic spraying of tungsten carbide coating can significantly improve the wear resistance of calended-steel rod and prolong its service life. In the process of paper production, the calendering steel roll plays an important role in the appearance quality and physical properties of paper. After the treatment of the calendering steel roll with supersonic spray tungsten carbide technology, the wear resistance of the steel roll is greatly improved, and the service life is extended from less than one year to more than three years.

Enhanced corrosion resistance

The supersonic spray tungsten carbide coating has good corrosion resistance, which can effectively resist the corrosion of the corrosive medium in the working environment to the calended steel rod, and improve its working stability in the harsh environment.

Improve surface quality

The supersonic spraying of tungsten carbide can make the surface of the calender steel rod more smooth and even, improve the gloss and smoothness of the paper, and improve the calender quality of the paper. For example, after a large paper enterprise uses supersonic spraying tungsten carbide technology to process the calender steel roller, the gloss of the paper is increased by more than 15%, the smoothness is significantly improved, and the thickness uniformity error is controlled within a small range.

High bonding strength

The combination strength of supersonic spraying tungsten carbide coating and matrix is high, which can ensure that the coating is not easy to fall off during use, and ensure the long-term stable operation of the calended steel rod.

Process maturity

The technology of supersonic spraying tungsten carbide is a mature surface engineering technology, which has the characteristics of simple operation, stable work, low fuel consumption, good coating performance, etc., and can meet the needs of the repair and strengthening of the calended steel rod.
