Abstract: The present invention concerns a plate (1) for cooling a blast furnace and forged or rolled out of a blank of copper or mainly-copper alloy.Vertical bores (3) extend into the plate. A detachable furnace-cooling component (4) with vertical bores (5) and horizontal bores (6) extending into it is attached to the top or bottom of the plate.Coolant is pumped into and out of the bores in the furnace-cooling component through sections (2) of pipe and into and out of the bores in the plate through other sections (2) of pipe. Both cooling systems communicate with the furnace's cooling system by way of the pipe sections (2), which extend through the furnace plating (10).

Abstract: A cooling element for shaft furnace walls including a metallic plate body with interior coolant-carrying tubes. The lower edge of the plate body includes a holding nose for refractory brickwork. The nose has at least one additional cooling tube. The cooling element according to the present invention may be assembled completely outside the furnace in a shop. The refractory brickwork consists of small bricks which are adhered or cemented to the plate body in concentric ring sections. The refractory bricks are advantageously provided with predetermined breaking notches and the layers of brick of the brickwork are provided with expansion joints. It is possible to use bricks with different thermal conductivities for the refractory brickwork.
