<p>A blast furnace cooling panel 1 comprises a metal backing plate 2, to which is secured a metal, preferably copper, cooling pipe 3 which has at least one outwardly extending fin 4 that is integrally formed with the pipe. In a first embodiment the fin 4 assists in catching slag and debris that circulates in the furnace during use, which protects the pipes and fins. In a second embodiment fin 4 assists in anchoring a refractory compound 9 in which the tubes and fins are embedded. The refractory material may be a cement-free refractory material containing no calcium aluminate cement and may be a colloidal silica refractory material. The backing plate 2 is preferably made of steel and may be copper clad steel, and the pipes 3 may be fixed to the plate with an interfacing pad 8 which may be of aluminium bronze material.</p> |
