COOLING PLATE FOR SHAFT FURNACES

摘要

The invention relates to a cooling plate (1) for a blast furnace, said plate being manufactured from a forged or rolled billet of copper or a lowalloy copper. A detachable cooling segment (4) containing its own vertical and horizontal blind bores (5, 6) is arranged at the top or the bottom of the cooling plate (1), which incorporates vertically arranged blind bores (3). The coolant flows to and from the blind bores (5, 6) of the cooling element (4) via separate pipe sections (2), while to and from the blind bores (3) it also flows via pipe sections (2), and both cooling circuits are connected to the cooling circuit of the blast furnace via the said pipe sections (2) running through the furnace shell (10).
