Abstract
The present invention concerns a slab (1) for cooling a blast furnace and made of a mass of copper or high-copper alloy forged or rolled into a blank. The edges of the slab accommodate narrower vertical and horizontal part-way bores (13 & 14) disposed around vertical part-way bores (3). Coolant is supplied to and removed from the narrower bores through sections (5 & 5') of pipe and to and from the other bores though connections (2 & 2'). The slab can be additionally secured to the furnace's armor by way of a cutout (12) in the surface facing away from the interior of the furnace and engaged by a bolt mounted on the armor. The slab is secured to the furnace by fasteners that engage threaded bores (9) in the slab.
