A COOLING PANEL FOR A FURNACE

摘要

A fabricated cooling panel (1) for a furnace or a cupola comprises a metal, preferably steel, backing plate (2) to which is secured a metal, preferably copper, cooling pipe (3). The pipe (3) has at least one outwardly extending fin (4) that is integrally formed therewith. In a first embodiment, the fin (4) catches slag and debris which circulate in the interior of the furnace during use. Alternatively, in a second embodiment, fin (4) assists in anchoring a refractory layer (9), which is applied to the interior side of the backing plate (2) and in which the pipe (3) and its integral fin (4) is embedded. The panel is particularly suitable for use in the reducing atmospheres found inside blast furnaces and iron smelting furnaces.
