Abstract

A cooling device for use with a refractory lining in a smelting plant, such as a blast furnace and particularly a shaft furnace, includes an inner refractory lining, an outer steel jacket, and a plate member located between them. Preferably, the plate member is cast and anchoring members are cast into each plate member and extend only from the plate member surface facing toward the steel jacket. The anchoring member secures the steel jacket and plate members together and also holds them in spaced relation. Various embodiments of anchoring members can be used. In one embodiment a blind bore is provided within the anchoring member and a thermocouple extends into the blind bore from the steel jacket for measuring the operating temperature of the plate member.
