摘要： A shaft furnace, e.g. a blast furnace, has a bosh, a shaft and a mantle ring at the transition from the bosh to the shaft. At both the bosh and the shaft, there is a steel jacket and a refractory lining on the inside of the steel jacket. Cooling elements extend into the refractory lining from the steel jacket and are arranged for through-flow of cooling liquid. To provide additional cooling at the critical transition from the bosh to the shaft adjacent the mantle ring, there is at least one transition cooling element located near the mantle ring so as to cool a region of the refractory lining of the bosh adjacent the steel jacket at the transition. The transition cooling element has, as seen in plan view, a T-shape, with the cross-bar of the T-shape extending in the circumferential direction of the furnace.
