Abstract
In a smelting plant including two melting furnaces which are arranged in juxtaposed relationship and which are operated alternately, wherein the furnace gases which are produced in the melting process are respectively introduced into the other melting furnace for the purposes of preheating the charging material, associated with each melting furnace is a shaft which is loaded with charging material, and the waste gases from the furnace which is in the melting mode of operation are introduced from the shaft, after charging of the other furnace, through the cover of the other furnace, and are removed from the shaft thereof. That procedure, throughout the entire smelting operation, permits preheating of charging material and filtration of the furnace gases when they are passed through the charging material.
