Title
(EN) DRAIN PUMP FOR A SPRAY-COOLED METALLURGICAL FURNACE
(FR) POMPE DE DRAINAGE DE FOUR MÉTALLURGIQUE REFROIDI PAR PULVÉRISATION
Abstract
(EN)
An apparatus is disclosed for a spray-cooled roof of a tilting metallurgical furnace having a drain pump. The spray-cooled roof has a hollow metal roof section. The hollow metal roof section has an outer metal covering member, an inner metal base member spaced from and opposite the outer metal covering member, an enclosed space disposed between the outer metal covering member and the inner metal base member, and a spray-cooled system disposed in the enclosed space. An evacuation drain is fluidly coupled to the enclosed space and a pump is integrated into the spray-cooled roof and coupled to the evacuation drain.
(FR)
L'invention concerne un appareil prévu pour un toit refroidi par pulvérisation d'un four métallurgique basculant comportant une pompe de drainage. Le toit refroidi par pulvérisation comporte une section de toit métallique creuse. La section de toit métallique creuse comporte un élément de revêtement métallique externe, un élément de base métallique interne espacé de l'élément de revêtement métallique externe et situé à l'opposé de ce dernier, un espace fermé disposé entre l'élément de revêtement métallique externe et l'élément de base métallique interne, et un système refroidi par pulvérisation disposé dans l'espace fermé. Un drain d'évacuation est en communication fluidique avec l'espace fermé et une pompe est intégrée dans le toit refroidi par pulvérisation et est raccordée au drain d'évacuation.
