介绍了2672烧结分厂1980年投产的2号烧结机的铺底料工艺,铺底料由振冷机分出,其粒度范围为9～20毫米;经三条皮带运输机倒运至铺底料矿槽;采用扇形闸门和摆动漏斗控制铺底料的布料,铺底料厚度为35毫米。生产实践表明,在全部用细精矿烧结、用生石灰作熔剂的条件下,使用铺底料效果显著:产量增加7.03%,FeO含量降低4.91%,转鼓指数提高4.30%,筛分指数降低0.73%,平均煤耗降低9.7公斤/吨,篦条消耗降低0.233公斤/吨。
Described the 2672 sintering plant put into operation in 1980 on the 2nd sintering machine sintering at the end of the material process, the bottom material from the cooling machine, the particle size range of 9 to 20 millimeters; transported by the three belt conveyor back to the bottom material trough; Gates and swinging funnels control the material at the end of the bedding. The thickness of the bedding is 35 mm. The production practice shows that under the condition of using all the fine ore sintered with quicklime as flux, the effect of using bottoming material is obvious: the output increases 7.03%, the content of FeO decreases 4.91%, the drum index increases 4.30% and the screening index decreases 0.73% , The average coal consumption decreased 9.7 kg / ton, grate bar consumption reduced 0.233 kg / ton.
