1. Cooling plates for shaft furnaces, in particular, for blast furnaces, provided with a refractory lining, comprising cooling channels (2) loadable by a cooling medium, wherein at least the front sides facing the interior of the furnace are comprised of ingots, produced preferably of copper or a low alloy copper alloy and provided with grooves (4) for receiving and securing refractory material, and wherein for each cooling plate two trough-shaped rolled sections (1, 3) of different size are welded to one another with their domed area facing outwardly, respectively, for forming the cooling channel (2) and wherein the smaller backside supplemental section (3) is provided with bores for receiving the ends of pipe connector pieces (12) that are welded thereto, and the free ends of the rolled sections (1, 3) are closed by caps (11), and wherein the front parts of the cooling plate located laterally adjacent to the cooling channel (2) overlap with corresponding parts of the neighboring cooling plates, respectively, in order to form a closed lining of the shaft furnace. 2. Cooling plate according to claim 1, characterized in that the backside supplemental section (3) is provided with a stay (5) projecting away from the shield (1). 3. Cooling plate according to claim 2, characterized in that the inner wall (9) of the shaft furnace is connected with holders (8) enclosing the stay (5), that the holders (8) and the stay (5) have bores (6, 6') aligned with one another which are penetrated by bolts (7). 4. Cooling plate according to any of claims 1-3, characterized in that on the front surface the shield (1) has the horizontal grooves (4). 5. Cooling plate according to any of claims 1-4, characterized in that on the domed area the shield surface is provided with preferably expanded texture.
