Problems solved by technology

At present, the industry usually uses Q345-B steel as the material of the steel wheel of the road roller. The surface hardness is about 150HV, and the hardness is limited. After 3000 hours of compaction in the rockfill dam, the surface of the steel wheel is severely worn and deformed. Steel wheels need to be replaced, and for construction sites such as hydropower stations in remote mountainous areas, the transportation of steel wheels is inconvenient, and the replacement operation is difficult and time-consuming, which affects the construction progress of the roller and will lead to an increase in construction costs
The existing technology provides a scheme of adding a wear-resistant layer on the surface of the steel wheel, but the degree of wear of the wear-resistant layer needs to be tested. After the wear-resistant layer reaches a certain degree of wear, it is necessary to weld the wear-resistant material again. The precision and detection accuracy are difficult to guarantee, the operation is difficult, the reliability of the steel wheel is poor, especially when it is used in a construction site in a remote mountainous area, it is difficult to maintain later, and the actual application effect is not good
