Background

The rolls are the main equipment for rolling steel, and the quality of the rolls plays a very critical role in the quality and quantity of the produced steel. At the same time, the rolls are also consumable parts of the rolling mill. After the roller is used for a long time in a rolling way, the radius of the middle part of the roller is reduced, and pits are formed on the surface of the roller, which can seriously affect the quality of rolled steel. To extend the useful life of a roll, it is often necessary to repair the working surface of the roll.

When the roller is repaired by laser cladding, the coaxial powder feeding head is driven by the mechanical arm to move to adjust the angle, and the alloy powder sent out by the coaxial powder feeding head is rapidly heated and melted on the surface of the matrix under the action of the laser beam emitted by the coaxial powder feeding head to form a surface coating of the matrix material and the metallurgical combination. Because the roller continuously rotates in the cladding process, the powder sprayed by the coaxial powder feeding head continuously falls off from the roller, so that a large amount of cladding powder is wasted, and meanwhile, the falling powder is not easy to clean. The existing powder collecting device needs to adapt to the size of the roller, so that when the different positions of the roller are repaired, the unused powder can be collected, the size of the collecting device is large, the occupied space is large, the application range is small, and the device is inconvenient to use flexibly.
