The surface of the hook roller is strengthened by thermal spraying

       There are many types of functional rolls used in the paper industry, such as rewinder rolls, sizing rolls, calender rolls, guide rolls, etc. Hook rolls are also one of the functional rolls that assist paper production. With the continuous upgrading of papermaking technology, machinery and equipment in the papermaking industry work under high speed, high temperature, high pressure, heavy load, corrosion and other media. Therefore, the requirements for the performance of mechanical surfaces are getting higher and higher.



This time, entrusted by the customer, the surface strengthening of the company's hook roll is carried out. For the surface strengthening of roller workpieces, there are many optional processes, such as supersonic spraying, plasma spraying, arc spraying, spray welding, etc. It should be noted that different functional rollers need to be based on their respective work. The parameters such as medium and surface strength requirements are used to select the spraying process and spraying material. For example, for the surface repair of the rewinder roll, the supersonic flame spraying process can be used to prepare the tungsten carbide coating on the surface; for the guide roll with high requirements on wear resistance and corrosion resistance, supersonic spraying or plasma spraying can be used first to prepare Anti-corrosion and wear-resistant alloy coating to meet surface requirements; in addition, Teflon coating can also be prepared by supersonic spraying process.



In the repair of the hook roller, the technicians of wococarbide.com will comprehensively consider the surface conditions of the workpiece, the material of the workpiece, the operating medium and other issues, and formulate a corresponding thermal spraying process plan to improve its surface strength.

For the preparation of functional coatings for papermaking equipment, the thermal spraying technology of wococarbide.com is relatively mature, and it has also saved customers a lot of economic costs over the years. For the surface strengthening and repair of workpieces in various industries, wococarbide.com will continue to carry out technical upgrades and strive to provide customers with better technical services.
