Abstract
A cooling plate for shaft furnaces, in particular, for blast furnaces, provided with a refractory lining, comprising cooling channels loadable with a cooling medium, wherein at least the front side facing the interior of the furnace is comprised of an ingot, produced preferably of copper or a low-alloy copper alloy and provided with grooves for receiving refractory material, is to be further developed such that it can be produced with a minimal material expenditure and a minimal manufacturing expenditure and can be easily mounted, and that with it a higher cooling capacity with reduced cooling medium throughput can be realized, wherein the own heat uptake is limited such that a significantly longer service life can be obtained. For this purpose it is suggested that two through-shaped rolled sections with their domed areas facing outwardly, respectively, are welded together and that bores for receiving the ends of pipe connector pieces are introduced into the backside supplemental section and the ends welded thereto, and that the free ends of the rolled sections are closed off by caps.
