摘要:

在焦煤中添加不同比例的钢渣进行炼焦,考察所得焦炭的热性能。焦炭反应性随着钢渣添加量增加逐渐增大,但存在一个饱和点,而焦炭反应后强度持续降低。比表面积和SEM研究显示反应性过大,焦炭的微孔扩大而相互贯通导致比表面积减小和反应后强度降低。钢渣颗粒在焦炭中均匀分布。

Abstract:

Different proportions of steel slag were added to coking coal to produce coke.Thermal property of coke produced was studied.The result showed that coke reactivity increased with the addition amount of steel slag until it reached a saturation point,while the coke strength after reaction decreased continuously.Specific surface area and SEM study showed that higher reactivity resulted in bigger pore size,which may link up each other,and consequently the specific surface area and coke strength after reaction were reduced.It was also observed that steel slag particles were uniformly distributed in coke.
