摘　　要：锰矿烧结具有燃耗高、烧损大、产品结构疏松等特点,在实践中利用系数一般较低。国内某铁合金厂为提高锰矿烧结产量,采用控制原料粒度等措施,使利用系数从0.95 t/(m^(2)·h)上升到1.05 t/(m^(2)·h)左右,取得较好效果。同时,为有效利用烧结过程中的余热,采用烧结余热利用烘干锰矿,每小时处理约50 t左右的锰矿,有效降低了能耗,创造了经济效益和社会效益。Manganese ore sintering has the characteristics of high fuel consumption,large burning loss,and loose product structure,and with lower utilization coefficient in practice in general.In order to increase the sintering output of manganese ore,a domestic ferroalloy factory adopted measures such as controlling the particle size of raw materials,which improved the utilization coefficient from 0.95 t/(m^(2)·h)to about 1.05 t/(m^(2)·h),achieving good results.At the same time,the use of sintering waste heat for drying manganese ore enables its fully utilization,which can process about 50 tons of manganese ore per hour,effectively reducing energy consumption and creating economic and social benefits for the factory.
