<p>In a furnace wall cooling device used for cooling blast furnace walls, etc., a blast furnace wall cooling panel, substituted for a stave cooler, which is lighter in weight, more inexpensive, and easier to produce. A blast furnace wall cooling panel which has no welded portions in a refrigerant path, the least possibility of water leakage, low cooling water pressure-loss, no stagnation, the capability to dispense with expansion pipes, and the capability to reduce the length of the pipe through which the refrigerant passes. A furnace wall cooling panel installed around the inner surface of a blast furnace wall, comprising a refrigerant pipe (2) of copper or copper alloy for passing a refrigerant therethrough, a plate (1) of copper of copper alloy having a cutout made to suit the size of the refrigerant pipe (2), the refrigerant pipe (2) being fitted in the cutout, the line of contact with the plate being welded. The cooling panel is provided with ribs (3, 4) for reinforcement.</p> |
