The wheelset of rail transit needs to withstand high-frequency vibration and heavy load friction. The surface hardness of traditional quenching treatment is only HRC50-55, with fast wear and excessive wheel flange wear. The service life is only 3-5 years, and the replacement cost is high.
The Daokedao laser cladding equipment melts a high hardness wear-resistant coating on the surface of the wheelset axle, with a hardness of HRC62-65, and the wear resistance is four times that of traditional quenching. The equipment has a low heat input and a wheelset axle deformation of ≤ 0.01mm, ensuring smooth track operation and increasing fatigue strength by 50%.
The service life of the strengthened wheelset axle has been extended to 8-10 years. After adopting this technology, a subway operating company has reduced the cost of wheelset replacement by 70%, saved over 1 million yuan in annual maintenance expenses, and improved the safety and economy of rail transit operations.
