摘要
钠基土膨润土粘性大、配加量小,使用钠基土是球团减少膨润土消耗的有效措施之一。针对济钢球团粘结剂消耗较高的情况,本文在对钠基土产地考察的基础上,分析了钠基土的化学成分与物理特性,在实验室对8个钠基土样进行了造球试验和球团指标测试,并根据试验数据,对钠基土实用效果进行了综合评价。结果表明,钠基土能有效降低球团膨润土用量,在保证生球质量下,钠基土与钙基土的替代比能达到1∶1.6左右,其中5#钠基土最优。
Owing to higher viscocity and lower dose of the sodium bentonite, therefore, use of sodium bentonite is one of the effective measures for decreasing consumption of bentonite in the pelletizing process. Aiming at the practical situation of higher consumption of bentonite in the pelletizing plant, on the basis of investigating production base of bentonite, the chemical composition and physical property of sodium bentonite are analyzed. The pelletizing tests for eight kinds of sodium bentonite samples are earned out and the major teehnieal indexes of these pellets are determined. The test results show that using sodium bentonite can effeetively decrease dose of bentonite in pelletizing process. On the premise of ensuring quality of green pellet, the substitution proportion of Na - bentonite to Ca - bentonite can reach around 1 ： 1.6. Among 8 samples the result of No. 5 Na - bentonite is optimal.
