Title
(EN) LINING AND COOLING ARRANGEMENT FOR A METALLURGICAL FURNACE
(FR) AGENCEMENT DE REVÊTEMENT ET DE REFROIDISSEMENT POUR FOUR MÉTALLURGIQUE
Abstract
(EN)
This invention relates to a lining and cooling arrangement for a metallurgical furnace. The arrangement includes a layer of refractory bricks located adjacent a furnace shell of the furnace, the layer of refractory bricks having a hot side that faces the inside of the furnace, and a cold side that faces the furnace shell. The arrangement also includes a cooling element located on top of the layer of refractory bricks, the cooling element having a hot side that faces the inside of the furnace, and a cold side that faces the furnace shell. A contact interface is defined between the top of the layer of refractory bricks and a bottom of the cooling element, and a containment ring, covering the contact interface, is located adjacent the cold sides of the cooling element and the layer of refractory bricks.

La présente invention concerne un agencement de revêtement et de refroidissement pour un four métallurgique. L'agencement comprend une couche de briques réfractaires située de façon adjacente à une enveloppe de four du four, la couche de briques réfractaires ayant un côté chaud qui fait face à l'intérieur du four, et un côté froid qui fait face à l'enveloppe du four. L'agencement comprend également un élément de refroidissement situé au-dessus de la couche de briques réfractaires, l'élément de refroidissement ayant un côté chaud qui fait face à l'intérieur du four, et un côté froid qui fait face à l'enveloppe du four. Une interface de contact est délimitée entre le haut de la couche de briques réfractaires et le bas de l'élément de refroidissement, et une bague de confinement, recouvrant l'interface de contact, est située de façon adjacente aux côtés froids de l'élément de refroidissement et de la couche de briques réfractaires.
