为探索铁矿粉配比和煤种对铁焦制备的影响，以40 kg 焦炉实验方式进行了现场混合煤和1／3焦煤的铁焦制备。研究表明：在1／3焦煤配比为50％～90％（质量分数）范围内，以1／3焦煤：铁矿粉为9∶1的效果最佳，M40为54．3％，M10为8．8％，金属化率可以达到60％左右，所得焦炭反应性 CRI 为42．5％，提高铁矿粉配比，则铁焦内部孔洞尺寸和数目增加，M40指标下降，M10指标上升，但 CRI 指标增加。
In order to explore the influence of iron ore proportion and coal type on the preparation of iron coke bri-quette,an investigation on iron coke preparation with mixed coal and 1/3 low quantity coal by 40 kg coke oven was carried out.The results show that when 1/3 coking coal was in the range of 50% to 90%,iron coke with 10% iron ores and 90% coking coal was be the best M40 and M10 were 54.3% and 8.8% separately,and the metal rate of iron coke was about 60%,CRI index reached 42.5%.The pore size and number increased in iron coke with increasing of iron ore proportion,and the quantity index M40 and M10 of iron coke deteriorated,whereas the CRI index improved.
