Title (EN) A METHOD FOR SEPARATING MILL SCALE FROM WASTEWATER
(FR) PROCÉDÉ DE SÉPARATION DE CALAMINE PRÉSENTE DANS DES EAUX USÉES
Abstract:
(EN) A method for collecting mill scale from a hot rolling mill is provided. The hot rolling mill includes a flume. The method includes transporting mill scale particles in wastewater, retrieving the wastewater from a flume of the hot rolling mill and separating the mill scale particles from the wastewater using a separator. A hot rolling mill and a method for retrofitting a hot rolling mill are also provided.
(FR) L'invention concerne un procédé de collecte de calamine à partir d'un laminoir à chaud. Le laminoir à chaud comprend une abée. Le procédé comprend le transport des particules de calamine dans les eaux usées, la récupération des eaux usées depuis une abée du laminoir à chaud et la séparation des particules de calamine et des eaux usées à l'aide d'un séparateur. L'invention concerne également un laminoir à chaud et un procédé d'équipement ultérieur d'un laminoir à chaud.
