| Abstract: | We obtained humic acid sodium which moulded lignite semi-coke used in ferroalloy plan from brown coal riching in Yunnan province. We studied the fabricating method of humic acid sodium and forming process of lignite semi-coke and tested strength indexes of moulded coke of different proportioning.Result shows that when humic acid sodium is used as glue of lignite semi-coke, it has good composite index. According to experiments, all indexes of moulded coke are perfect when the addition of humic acid sodium is over 8%. And it identifies the requirement of ferroalloy furnace. |
