| 摘要 |
The invention relates to a method and apparatus for sintering finely divided material, containing manganese compounds with a particle size less than 6 mm and a high degree of oxidation, by means of some carbon-bearing material in a conveyor-type sintering apparatus (9) in an essentially continuous operation. According to the invention, through the material (8) to be sintered in the sintering apparatus (9), there is conducted hot gas (15, 18), which causes combustion reactions between the manganese compounds contained in the material and having a high degree of oxidation and the carbon contained in the burning material. Thus the sintering (18) is carried out essentially by means of the combustion heat released from the material (8). Moreover, the sintered material (8) is subjected to cooling (17) prior to removing the material from the sintering apparatus (9).
