铁矿烧结的现有方法有四个主要的缺点:1.用冷却空气烧结时会延长烧结过程的时间和降低设备的效率;2.能量平衡由于团矿中热的大量损失而恶化;3.炽热成品须在各种辅助设备中(如冷却带,回转冷却器,喷水咀等)冷却,因而增加了设备的投资和操作费用,提高了对空间的要求,并在某些情况下 The existing methods for sintering iron ore have four major drawbacks: 1. Sintering with cooling air prolongs the sintering process and reduces the efficiency of the equipment; 2. The energy balance deteriorates due to the massive loss of heat in the mines; The hot finished product must be cooled in a wide range of ancillary equipment (such as cooling belts, rotary coolers, water jets, etc.), thus increasing equipment investment and operating costs, increasing space requirements and, in some cases,
