Title:
DESCALING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/136734
Kind Code:
A1
Abstract:
Provided is a descaling system capable of removing scale more efficiently. The descaling devices (40, 50, 60) in the descaling system (1) have descaling nozzles (41, 51, 61) for spraying water on the surface of a steel plate (K) thereby removing scale formed on said surface. The descaling nozzles (41, 51, 61) are connected to pumps (70) that pressurize water from a water supply source (100) and spray water pressurized in the pumps (70) onto the surface of the steel plate (K). The entry side of the pumps (70) is provided with a de-aerating device (90) that reduces the dissolved oxygen concentration in the water to be delivered to the pumps (70) below the dissolved oxygen concentration in the raw water from the water supply source (100).
