摘　　要：采用煤气发生炉供热、立窑碳还原连续焙烧、数字显示仪表指示炉内温度、隔绝空气冷却等新技术,解决了对二氧化锰还原高效、能源消耗节约、劳动强度降低、产品质量稳定和环境保护得到加强等的效果。实现了对低品位二氧化锰[MnO2≥25%(质量分数)]矿粉焙烧还原率在93%以上。特别是通过该研究为低品位二氧化锰矿的高效利用找到了途径,解决了过去使用其它窑炉还原焙烧二氧化锰矿中存在的很多技术难题。With heat supplied by gas producer,and roasted continuously in furnuee, temperature conditioning and refrigeration etc are of new technology. It seems a correct way, compared with another farnace, that has some advantages in high efficiency there in resources utilization. It decreases in energy consumption, labour improving and quality assurance. It reinforces environment protection and achievement of low grade powder of converting rate over 93%. And it solved the technial problems of any other with reducing roasting furnace method.
