A trough is described for carrying molten metal, comprising an outer shell defined by a bottom wall and two side walls, an insulating layer filling the outer shell and a conductive U-shaped refractory trough body for carrying molten metal, the trough body being embedded in the insulating layer. At least one heating element is positioned in the insulating layer, adjacent to but spaced apart from the trough body, to provide an air gap between the heating element and the trough body.
La présente invention concerne une goulotte permettant de transporter du métal en fusion, comprenant une coque extérieure définie par une paroi de fond et deux parois latérales, une couche d'isolation remplissant la coque extérieure et un corps de goulotte réfractaire en forme de U destiné à transporter du métal en fusion, ce corps de goulotte étant confiné dans la couche d'isolation. Au moins un élément chauffant est placé dans la couche d'isolation, à côté mais séparé du corps de goulotte, de façon à fournir un vide d'air entre l'élément chauffant et le corps de goulotte.
