     · Descaling is a key process of hot rolling especially when a good surface quality of the hot rolled products is demanded. Many studies have been made on the descaling technique of the hot strip mill (HSM) process (1-3). The key descaling parameters include the facility the descaling performance and the descaling conditions (Figure 1).

    Hot Rolling Mill. The present invention provides a descaling system for hot strip or plate mills. The descaling system includes upper and lower spray headers which are offset from each other along the pass line. Each spray header is adapted to direct a high-pressure water spray on the metal product to descale the upper or lower surface thereof.
