程潮球团配加毛粉的生产试验
|
摘要
采用程潮自产磁铁精矿、毛里塔尼亚铁精矿(简称毛粉)开展了球团配矿试验,考查了毛粉配比对生球、预热球及成品球质量的影响,观察了不同毛粉配比下热工参数的变化情况。试验结果表明,配加毛粉能改善生球质量,毛粉配比控制在15%以内,热工参数稳定,成品球质量满足炼铁需要。
The ore blending test was carried out by using Chengchao self-produced magnetite concentrate and Mauritania iron ore concentrate powder( referred to as Mao powder). The effects of Mao powder ratio on the quality of green ball,preheated pellet and finished pellet were investigated,and the changes of thermal parameters under different Mao powder ratio were observed. The test results show that the quality of green ball can be improved by adding Mao powder. The proportion of Mao powder can be controlled within 15%,the thermal parameters are stable,and the quality of finished pellet can meet the needs of iron-making.
