摘要： A hearth for a metallurgical reactor, in particular for a blast furnace, has an outer shell and an annular wall lining of refractory material inside the shell, the wall lining having a lower region with a multi-layered construction a radially inner layer faces the interior of the hearth and includes at least one inner ring of refractory elements, radially outer layer faces the outer shell and has at least one outer ring of refractory elements, where in the at least one inner ring elements are made of a first carbonaceous refractory material that is different from one or more carbonaceous refractory materials of the elements in the outer layer such that, the first refractory material contains, in a proportion of at least 5% by mass in total, at least one property-enhancing additive other than metallic silicon or silicon carbide. In beneficial combination therewith, the at least one inner ring has a wall thickness of less than 45%, of the corresponding total wall thickness of the wall lining.
