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.

A method for venting a spray-cooled roof of a ladle metallurgical furnace having an integrated hood:
- processing molten metal materials in a ladle metallurgical furnace;
- the spray-cooled roof comprising a central opening having sidewalls defining the opening, the opening configured for one or more electrodes to pass there through;
- extracting process gases and fumes in the opening through a channel having an inlet formed in the sidewalls of the opening, wherein the channel has walls disposed within an enclosed space of the spray-cooled roof;
- and cooling the walls of the channel with a spray-cool system that extends between the walls of the channel and a top of the spray-cooled roof.
A method for cooling a channel for venting fumes in a spray-cooled roof of a ladle metallurgical furnace, the spray-cooled roof comprising a central opening having sidewalls defining the opening, the opening configured for one or more electrodes to pass there through the method comprising;
- extracting process gases and fumes in the opening through a channel having an inlet formed in the sidewalls of the opening;
- wherein the channel has walls disposed within an enclosed space of the spray-cooled roof;
- and cooling the walls of the channel with a spray-cool system that extends between the walls of the channel and a top of the spray-cooled roof.
