对采用有机粘结剂球团生产DRI产品的评价
Evaluation of DRI Produced with Organic Binder Pellets

摘要: 以氧化铁皮为原料,采用有机粘结剂"CC"和以皂土为粘结剂,生产球团作对比试验。结果表明:有机粘结剂"CC"和皂土均可降低生球长大速度,提高生球、干球落下和抗压强度,但生产同样质量的球团矿,"CC"的用量只有皂土用量的1/10。且其直接还原铁(DIR)产品质量优于皂土球团。Abstract: This paper compared "CC"-pellets(pellet with organic material as binder), using roll scale as raw material and low cost coal as reductant. The results showed that "CC" and bentonite may reduce growth speed of green pellets and increase strengths of green and dry pellets, but "CC" addition rates were only one-tenth of that of bentonite producing the same quality pellets. DRI (Direct Reduction Iron)produced with "CC"-pellets were superior to that of bentonite pellets.
