Abstract
A method for venting a spray-cooled roof of a ladle metallurgical furnace is provided herein. The method begins by processing molten metal materials in a ladle metallurgical furnace having a spray-cooled roof with an opening configured for one or more electrodes to pass there through and an integrated hood. Process gases and fumes are extracted through a channel having walls disposed within an enclosed space of the spray-cooled roof. The walls of the channel are cooled with a spray-cool system extends between the walls of the channel and a top of the spray-cooled roof.
