Description

Technical Field

[0001] This application relates to the field of descaling machine technology, and more particularly to a dust-blocking roller for a finishing descaling machine in a steel rolling mill. Background Technology

[0002] In a conventional hot rolling production line, the slab needs to be passed through a flying shear head and then enter the finishing descaling mill for descaling. During descaling, high-pressure water is sprayed onto the surface of the slab to remove the iron oxide scale generated on the surface of the slab due to high temperature. Therefore, the descaling machine is also called an oxide scale cleaning machine.

[0003] Currently, Chinese patent announcement CN117505559A discloses a descaling machine with a water-blocking roller device. This descaling machine includes a frame and an inlet roller mounted on the frame. A water-blocking roller is positioned above the inlet roller, making rolling contact with it. A connecting structure is provided between the water-blocking roller and the frame. The frame has an elongated hole, the length of which aligns with the height of the frame. One end of the connecting structure is hinged to the elongated hole, and the other end is rotatably connected to the water-blocking roller. This allows the water-blocking roller to rotate by the movement of the slab. Furthermore, the hinged connection between the water-blocking roller and the elongated hole on the frame allows the water-blocking roller to move and deflect above the inlet roller via the movement of the slab. This ensures that the water-blocking roller adheres to the upper surface of the slab during descaling, effectively blocking the descaling water and preventing it from splashing into the flying shears.

[0004] In practical use, it was found that the existing device uses a water-blocking roller to block descaling water and metal shavings, but the height of the water-blocking roller cannot be automatically adjusted for slabs of different thicknesses, resulting in low applicability and inconvenience in use. Therefore, we proposed a dust-blocking roller for a finishing descaling machine in a steel rolling mill to solve the above problems. Utility Model Content
