摘要
研究了程潮铁矿球团原料条件下,配加膨润土、有机粘结剂—羧甲基纤维素钠(CMC)、以及二者的复后粘结剂对球团生产及球团矿质量的影响。结果表明,在1.5%膨润土+0.05%羧甲基纤维素钠(CMC)复合的条件下,取得了良好的试验效果,生球落下强度>6次/个,抗压强度>10 N/个,爆裂温度>600℃,成品球抗压强度>2 500 N/个。
The effect of adding bentontie,organic binder-sodium carboxymethyl cellulose （CMC）and compound binder of the two on pellet production and pellet quality under raw material condition of Chengchao pellet was studied. The result shows that,with addition of 1.5% bentonite ＋ 0.05% CMC,good experiment result is achieved with green ball drop number 〉 6 times/piece,the compression strength of green ball 〉 10 N/piece,shock temperature 〉 600 ℃ and compression strength of product pellet 〉 2 500 N/piece.
