Abstract

Installation de traitement thermique de pièces métalliques. Elle comprend un châssis comportant des éléments horizontaux supérieurs 3, des éléments latéraux verticaux et, le cas échéant, des éléments horizontaux inférieurs. Les éléments horizontaux supérieurs du châssis sont constitués par des tubes qui présentent des orifices 12 destinés à projeter un gaz inerte pour former un rideau empêchant les fumées dégagees du bain de s'échapper à l'extérieur d'une hotte 7 munie d'un dispositif d'extraction. Le rideau de gaz inerte est dirigé vers ce dispositif d'extraction. Application : traitement thermique de pièces métalliques.Installation of heat treatment of metal parts. It comprises a frame comprising upper horizontal elements 3, vertical side elements and, where appropriate, lower horizontal elements. The upper horizontal elements of the frame are formed by tubes which have orifices 12 intended to project an inert gas to form a curtain preventing the fumes given off from the bath from escaping outside a hood 7 fitted with a device. extraction. The curtain of inert gas is directed towards this extraction device. Application: heat treatment of metal parts.
