Solution

Papermaking machinery industry

The mechanical equipment in the papermaking industry works under high-speed, high temperature, high pressure, heavy load, corrosive media. The wear, scratches and scratches of its mechanical equipment and various rollers, and the damage of corrosion, high-temperature oxidation and other damages start from the surface, gradually causing failure of parts, which is the main factor restricting the production and quality of paper products.

Solution:

‌Thermal spraying technology is widely used in repairing and strengthening calendering rollers, drying cylinders, rubber applying rollers, multi-section rollers, rewinder rollers, corrugated rollers and other components. The preparation of functional coatings for papermaking equipment is a comprehensive and mature part of the company's service scope, and has created economic benefits for the papermaking industry over the years. Our company has experience in paper mirror drying cylinders and various roller processing, mature technology and strong technical strength, increasing the finish and hardness of the equipment surface, reducing production costs, and improving paper quality.
Repair of life enhancement and repair of inner walls of steamers, drying cylinders, and ovens; strengthening and repairing of various roller surfaces; repair of parts such as centrifugal pumps, axial flow pumps, steam boilers, valves and mixer shaft seals; strengthening of surface corrugated rollers (after strengthening treatment, the surface hardness of corrugated rollers can be increased to HV1200, and the working life of corrugated rollers can reach more than 40 million meters).
