加料的方式也必須兼顧生成母球和母球長大，要防止形成過多的母球。在保證生球達(dá)到要求尺寸的前提下，應(yīng)使母球的生成速度與生球的長大速度達(dá)到平衡。滾動(dòng)成球的時(shí)間，與對球團(tuán)礦粒度的要求，以及原料成球的難易有關(guān)。球團(tuán)礦的粒度大，要較長的造球時(shí)間；原料成球性差，造球時(shí)間也會(huì)延長。一般的規(guī)律是：延長造球時(shí)間，有利于提高生球的強(qiáng)度，特別對于粒度很細(xì)的原料，更須要較長的造球時(shí)間，才能使生球具有更高的強(qiáng)度。生球品質(zhì)的控制生球不是終產(chǎn)品，但是它的品質(zhì)，在很大程度上決定了下一步焙燒工序能否順利進(jìn)行，以及成品球團(tuán)礦的品質(zhì)。

周而復(fù)始地這樣操作高爐，使高爐形不成合理爐型，高爐一直在波動(dòng)之中生產(chǎn)，也不會(huì)有好的生產(chǎn)指標(biāo)。爐溫波動(dòng)大的現(xiàn)象經(jīng)常出現(xiàn)，爐溫一低，有的高爐就臨時(shí)加焦，防止?fàn)t溫下滑太大。實(shí)際上，爐溫低是錯(cuò)誤操作所造成的，如崩料、連續(xù)滑尺，有管道行程，煤氣流分布不合理等。臨時(shí)加焦抵達(dá)爐缸后，爐況已恢復(fù)正常，會(huì)使?fàn)t溫升高，導(dǎo)致高爐難行。建議一般不進(jìn)行臨時(shí)加焦處理。調(diào)劑負(fù)荷時(shí)，采取調(diào)劑焦炭量的方法是錯(cuò)誤的操作。焦炭在高爐內(nèi)是個(gè)透氣窗，希望焦批量固定（焦炭在爐喉處有400mm以上的厚度），使煤氣流穩(wěn)定、通暢。
