高炉炼铁中使用小颗粒焦炭替代部分冶金焦波兰在３２００ｍ３高炉上进行了该项目的试验。试验时，按照每吨融熔金属投入小颗粒焦炭（粒径１０～２５ｍｍ）４０ｋｇ（占全部焦炭量的８％～９％），这时不会影响炉料的透气性。这种小颗粒焦炭既可以通过上料皮带加入，也可由... Small pellet coke used in blast furnace ironmaking to replace part of metallurgical coke Poland conducted a pilot project on a 3200m3 blast furnace. Test, according to the amount of molten metal into the small particles of coke (particle size 10 ~ 25mm) 40kg (accounting for all the coke amount of 8% to 9%), then does not affect the gas permeability of the charge. This small particles coke can be added through the feeding belt, but also by ...
