摘要： 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.

摘要： To diminish cracking due to differential expansion of refractory channels conducting molten materials, e.g. in an iron runner or iron trough, lateral pressure is exerted inwardly on the wear lining of such a channel through intermediate layers of permanent lining. These may include low friction slide plates and at least one layer having a high thermal conductivity. The means exerting the pressure react against an external frame structure and are preferably such that the pressure exerted is independent of the degree of expansion of the channel.
