COOLING PLATE FOR SHAFT FURNACES

摘要

A cooling plate for shaft furnaces, particularly blast furnaces, is provided with a refractory lining and is composed of copper or a low-alloy copper alloy with cooling medium ducts, wherein the cooling plate is made from a wrought or rolled ingot, and wherein the cooling plate has on one side thereof, i.e., the front side, grooves for receiving refractory material. Cooling ducts are provided on the rear side of the cooling plate, wherein the cooling ducts are defined in part by the cooling plate itself and in part by sheet metal or sheet steel, wherein the cooling ducts are produced by milling cutting in the rear sides of the cooling plate and/or the sheet metal or sheet steel.
