HOT ROLLED SLAB IMPACT TYPE MECHANICAL SCALE REMOVAL DEVICE

摘要

A hot rolled slab impact type mechanical scale removal device comprises a front cooling water nozzle group (4), an impact type scale removal gear roller group (5), a roller cooling device (6) and a cleaning water nozzle group (9). A slab (1) moves on a slab roller table (3). The front cooling water nozzle group (4), the impact type scale removal gear roller group (5) and the cleaning water nozzle group (9) are arranged in sequence along the movement direction of the slab. The impact type scale removal gear roller group (5) is arranged on a support seat (8). The cooling water nozzle of the roller cooling device (6) is arranged corresponding to the impact type scale removal gear roller group (5). According to the scale removal device, the oxide skins can be clearly removed, the temperature of the continuous casting slabs can be reduced and the hot rolling quality is improved.
