"A shaft furnace, particularly the refractory construction of the bottom thereof" ABSTRACT OF THE DISCLOSURE The refractory bottom of a shaft furnace, e.g. a blast furnace has a graphite layer, above it an intermediate layer of lower coefficient of thermal conductivity ( .lambda. -value) and above the intermediate layer a third layer of yet lower .lambda.-value. To control the penetration of molten metal into the bottom and in particular to achieve a stable location of the solidification isotherm in the intermediate layer, the material of the intermediate layer is one having a .lambda. -value of 12 to 30 kcal/m.h.°C. This material may be semi-graphite. Such material does not undergo a change of .lambda. -value when permeated by the molten metal.
