摘　　要：本文介绍了原料粒度、粘结剂用量、配碳量时铬铁矿球团生球性能的影响以及温度和还原时间对金属化率的影响，结果表明：１３５０℃还原１５ｍｉｎ，铬金属化率达９０％以上；配碳量应比理论配碳量过量２０％；用１：３的Ｈ２ＳＯ４对还原球团采用加热回流法溶样，解决了金属铬和金属铁的化学分析问题。Balling and reducing experiments of carbon-bearing chromite powder were carried out in laboratory. The effect of grain size of raw materials .amount of binder and carbon and other factors on the green pellet properties and the influence of reducing temperature and time on the metallization rate of carbon bearing chromite pellet were investigated.The results from laboratorial experiments have shown that the metallization rate of carbon-bearing chromite pellet of up to 90% and more can be reached under the r...
