Continuously operating liquid-cooled panel

摘要

The present invention is a dual section liquid-cooled panel that lines a portion of the interior surface of a metallurgical furnace. The invented panel has a primary section disposed proximate to the center of the furnace and a secondary or back-up section adjacent the primary section. A three-way valve is controls the flow of fluid to the operating section of the panel. Initially, the primary section is operational and the valve is set to permit the flow of fluid to the primary section. If the primary section suffers structural damage, the valve can be used to re-direct the cooling fluid to the secondary section of the invented panel and the secondary section becomes operational until regular maintenance is scheduled to occur. Also disclosed is a method for repairing a damaged dual section liquid-cooled panel.
