Hot rolled slab impact type mechanical scale removal device

A mechanical descaling device of a impact type for hot rolled slab, characterized in that the device comprises a front cooling water nozzle group, a descaling gear roller group of a impact type, a roller cooling device and a cleaning water nozzle group;

• the slab moves on a slab roller table;
• the front cooling water nozzle group, the descaling gear roller group and the cleaning water nozzle group are arranged in sequence in the moving direction of the slab;
• the descaling gear roller group is mounted on a support seat, and cooling water nozzle of the roller cooling device are provided corresponding to the descaling gear roller group;
• wherein, the descaling gear roller group comprises a main shaft, descaling gear assembly shaft and descaling gear group, a plurality of the descaling gear assembly shafts in a ring array with a center at central-axis of the main shaft are supported by fixed plates disposed on the main shaft;
• for each descaling gear assembly shaft, a row of descaling gears of one descaling gear group are mounted thereon in series;
• the descaling gear roller group is inclined at an angle with the moving direction of the slab.
