冶金焦的质量是影响炼铁焦比和高炉操作的重要因素之一。焦炭整粒是高炉精料工作的重要部分。试验结果表明,如果用粒度为40～80mm的焦炭去代替含有20％大于100mm的普通焦炭,则在相同焦比情况下,其产量将增加10％;或者,在相同生产水平下,焦比将降低10kg/t铁。影响焦炭粒度的因素有;煤的质量、炭化室宽度、加热速度和火道温度。把过 The quality of metallurgical coke is one of the important factors that affect the iron-making coke ratio and blast furnace operation. Coke whole grain blast furnace concentrate is an important part of the work. Test results show that if coke with a particle size of 40 to 80 mm is used instead of ordinary coke containing 20% ​​of more than 100 mm, the yield will increase by 10% at the same coke ratio; or, at the same production level, the coke will be Reduce 10kg / t iron. Factors that affect the coke size are: coal quality, carbonization chamber width, heating rate and flue temperature. Put it over
