DESCALING SYSTEM

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 (4...

Summary: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). La présente invention concerne un système de détartrage pouvant retirer le tartre plus efficacement. Les dispositifs de détartrage (40, 50, 60) du système de détartrage (1) possèdent des buses de détartrage (41, 51, 61) destinées à pulvériser de l'eau sur la surface d'une plaque d'acier (K), ce qui permet de retirer le tartre formé sur ladite surface. Les buses de détartrage (41, 51, 61) sont raccordées à des pompes (70) qui mettent sous pression l'eau provenant d'une source d'alimentation en eau (100) et qui pulvérisent l'eau mise sous pression dans les pompes (70) sur la surface de la plaque d'acier (K). Le côté entrée des pompes (70) est doté d'un dispositif de désaération (90) qui réduit la concentration en oxygène dissous dans l'eau à distribuer aux pompes (70) sous la concentration en oxygène dissous dans l'eau brute provenant de la source d'alimentation en eau (100).
