Abstract
An apparatus and method for cooling the interior wall of an electric arc furnace. The device is an extruded heavy-walled pipe having a base and a fin or plurality of fins.
Such pipes are attached to a plate in serpentine fashion and hung on the inside wall of the electric arc furnace above the hearth, thereby forming a cooling surface between the interior and the furnace wall. The fins are sized and arranged to retain splattered slag. The stags solidifies on the pipes, forming an insulation barrier between the molten iron material and the cooling pipes and, consequently, the wall of the furnace.
