为鞍钢即将投产的200万t 球团厂选择合适的粘结剂,作者对品种选择及最佳配比进行了试验研究,从而得出这样结论:①在鞍山的原料条件下,东北地区的几种膨润土作为粘结剂时,以刘房子膨润土为最佳.其配比为0.8%时,生球落下强度达5.5次/个球,抗压强度达14N/个球,千球抗压强度为41.2N/个球,成品球团的抗压强度达到2625.3N/个球。配比增至1.0%和1.3%时效果更好;②凌源膨润土和黑山人工钠化膨润土的使用效果也较好。二者配比在1.0%时,生球、干球、成品球的强度指标和生球爆裂强度均能满足带式球团工艺要求;③用自产精矿代替大浮精矿配加刘房子膨润土所造生球各项指标若要满足工艺要求,粘结剂的配比只能在1.0～1.3%。
Anshan Iron and Steel is about to put into operation 2 million t pelletizing plant choose the right binder, the author of the species selection and the best ratio of the pilot study, which concluded: ① raw materials in Anshan, the Northeast a few When bentonite is used as a binder, bentonite of Liu house is the best.When the ratio is 0.8%, the dropping strength of green ball reaches 5.5 times / ball, the compressive strength reaches 14N / ball, the compressive strength of 1000 ball 41.2N / ball, finished pellets compressive strength of 2625.3N / ball. When the ratio is increased to 1.0% and 1.3%, the effect is better; ② The effect of using Lingyuan bentonite and Montenegro artificial sodium bentonite is also better. Both the ratio of 1.0%, the ball, dry ball, finished ball strength indicators and ball burst strength can meet the requirements of the belt pellet process; ③ with self-produced concentrate instead of floating ore plus Liu house Bentonite made balls all the indicators to meet the process requirements, the binder ratio can only be 1.0 to 1.3%.
