Patent attributes
A process for sintering metal-containing materials, such as iron ores or manganese ores, on a sintering machine including a sintering belt for transporting the sinter mix during sintering thereof. The sintering belt has first, second and third portions. Sintering waste gas from the third portion is transported to and unified with sintering waste gas from the first portion in a mixing region to form a mixed gas, wherein the transporting distance of the sintering waste gas from the third portion to the mixing region is greater than the transporting distance of the sintering waste gas from the first portion to the mixing region. An apparatus for carrying out the process is disclosed, including the sintering belt, suction boxes operative at the portions of the belt, and lines for conveying the gas produced and the gases used in the process.
