在2 kg试验焦炉开展配白煤炼焦试验，研究了煤粉改性剂（zzz）对配合煤、焦炭质量的影响。确定出白煤的最佳配加粒度、最佳配加量以及zzz的最佳配加量。通过试验确定出最佳配煤方案：白煤配加量达到8%（粒度小于3 mm），zzz量配加0.10%。由最佳试验方案炼得焦炭的冷态强度M40、M10和热态性质CRI、CSR都可以达到南钢生产焦炭质量的水平。试验方案在南钢40 kg试验焦炉中进行也取得了很好的效果。
The coking test of blending hard coal was carried out in 2 kg cokingoven.The influence of coal modifying additive (zzz) on blend coal and coke quality was studied.The optimal size and quatity of hard coal and zzz have been chosen.The experimental results show that the optimal proposal of coal blending is of that hard coal added up to 8%(its size under 3 mm) and zzz added to 0.10%.The value of M40、M10 and CRI、CSR of coke from the optimal proposal can be up to the level of coke produced in Nanjing Iron and Steel (group) Co.,Ltd.This test also gains a good result on 40 kg testoven.
