A coolant fluid chamber is affixed to the shell of an electric arc furnace to cool and decrease erosion of the refractory lining of the furnace caused by localized heating and arc flaring. The wall of the cooling chamber adjacent the furnace shell comprises a diaphragm or sheet of flexible material which is subject to deformation when the space between it and the furnace shell is evacuated and the sheet is pressed. The interface between the diaphragm and shell is coated with a flowable or deformable heat conductive material prior to attachment of the chamber to the furnace so that this material will flow into any void spaces in the interface to thereby enhance thermal conduction. |
