Abstract:
1. A system for conditioning scale on the surface of a metal object comprising: at least one nozzle adapted to spray droplets of an aqueous caustic solution; at least one reservoir for containing said aqueous caustic solution communicating with said at least one nozzle; a driving mechanism positioned to move the metal object relative to said at least one nozzle; a temperature-sensing device positioned to sense the temperature of the surface of said metal object prior to the metal object passing said at least one nozzle, a temperature modifier mechanism adjacent said temperature-sensing device, and a computer control unit in communication with the said temperature sensing device, the said temperature modifier mechanism, the said reservoir and the said nozzle to control said temperature modifier mechanism responsive to the sensed temperature of the surface of said metal object, said temperature modifier mechanism configured to responsively modify the temperature of the metal object until the sensed temperature is in a specified temperature range.
