The process for secondary descaling steel strips, comprises uncoiling the steel strip while hot rolling the strip, projecting water on the surface of the strips under pressure using spray nozzles, and regulating the nozzles to deliver a water flow on the strip surface similar to the water flow delivered under high pressure. The nozzles are fed with a low hydraulic pressure of 4-10 bars to ensure a thermal effect of water. The secondary descaling is carried out in upstream of a finisher- and reducer enclosure, which are in upstream of a hot strip rolling train. An independent claim is included for an apparatus for secondary descaling the steel strips. |
