什么叫未燃煤粉?它對(duì)高爐冶煉有何影響?高爐噴煤實(shí)踐和研究表明,在高爐煉鐵的條件下,噴入爐缸的煤粉在有限空間和短暫的時(shí)間內(nèi)不可能100%完全氣化,而且揮發(fā)分中碳?xì)浠衔镞€不可避免地產(chǎn)生有很高抗表面氧化能力的炭黑微粒,這些就是噴煤操作中稱為未燃煤粉的來源。未燃煤粉數(shù)量與煤粉的燃燒性能,特別是煤粉的粒度、鼓風(fēng)中含氧、風(fēng)口工作的均勻性等有關(guān)。一般要求未燃煤粉量應(yīng)低于噴煤量的!15~20%。超量的未燃煤粉隨煤氣進(jìn)入料柱將會(huì)產(chǎn)生對(duì)高爐行程不利的影響,它們是:大量進(jìn)入爐渣超過直接還原所要求的數(shù)量,以懸浮狀存在于爐渣中,會(huì)增加爐渣的黏度,嚴(yán)重時(shí)造成滴落帶渣流不順利和爐缸堆積,這對(duì)攀鋼等特殊礦冶煉影響尤為嚴(yán)重。
