Abstract

The cupola consists of a shaft mounted above a hearth used for additional heating of the molten metal, the shaft and the hearth being sepd. by transverse, water-cooled tubes covered with a refractory and located at a sufficient distance from the side walls so that the hot gases can travel upwards and the molten metal can flow downwards. The novelty is that the water-cooled tubes are arranged as pairs, forming a "bridge", and at least two rows of bridges are used, the upper row being staggered so it covers the bridges in the lower row and rings of refractory matl. are used as the coating for the tubes. The amt. of stagger used in one row of bridges w.r.t. the underlying row is pref. 0.3-1.5 times the vertical distance between the rows. The arrangement gives even distribution of the hot gases across the entire cross section of the cupola and longer life of the bridges; more efficient operation of the cupola is achieved.
