ABSTRACT:
A system for descaling a strip of metal includes a nozzle assembly mounted within a spray box for spraying descaling product on the strip. The nozzle assembly includes a spray chamber; nozzles mounted directly to the spray chamber; and a heater for heating the chamber, the descaling product in the chamber, and the nozzles by conduction through the chamber. The nozzles are oriented to direct the descaling product in a spray against the upper and lower surfaces of the metal strip for an amount and a time sufficient to descale the metal strip. The nozzle assembly is attached to the spray box and can be easily removed therefrom for inspection.
