The drying cylinder shaft of a paper machine is subjected to high temperatures (above 180 ℃) and axial loads. Traditional arc welding repair requires a large amount of heat input, and the deformation of the shaft exceeds 0.3mm, resulting in eccentric operation of the drying cylinder and paper wrinkling. The success rate of repair is less than 60%.
The Daokedao laser cladding equipment adopts high-temperature environment precise cladding technology, with low heat input and controlled drying cylinder shaft deformation within 0.05mm, without the need for subsequent calibration. High temperature resistant alloy powder is selected, and the strength retention rate of the cladding layer reaches 95% at a high temperature of 200 ℃.
The service life of the repaired dryer shaft has been extended to 3-4 years. After a certain paper mill adopted this technology, the pass rate of paper flatness has increased by 18%, and the annual waste loss has been reduced by more than 300000 yuan, which is suitable for the continuous production needs of the paper industry.
