Abstract
Refractory wall structure for a blast furnace, in particular for a metallurgical furnace, such as for example a blast furnace with a high process temperature during operation, which wall structure is subjected to a high thermal loading. The wall structure comprises a steel outer wall, a refractory lining consisting of one or more layers of a well heat-conducting material on the inside of the outer wall, and a cooler for cooling the refractory wall structure, whereby the wall structure also comprises a permanent, well heat-conducting metallic filling in a gap in the refractory wall structure, which filling has been molten inside the gap and then after solidifying forms a low heat resistance across the gap.
