摘要
因为环保和市场的需要,转底炉处理钢铁厂含铁尘泥及废弃物技术正在国内呈现出蓬勃的生命力。目前,国内已有多条转底炉直接还原生产线投入运行,转底炉技术能直接利用废弃粉尘中的碳还原氧化铁和氧化锌,金属化率达到70%,脱锌率达到80%,有效的解决了钢铁企业含锌粉尘的回收和利用。
Because of the need for environmental protection and market,furnace steel plant iron dust and waste technology is now full of vitality to the end. At present,there are a number of rotary hearth furnace direct reduction production line put into operation,the rotary hearth furnace technology can directly use the waste dust in carbon reduction of iron oxide and Zinc Oxide,metallization rate reached 70%,zinc removal rate reached 80%,effective solution containing zinc dust recovery and utilization of iron and steel enterprises.
