研究表明,在冷固结球团矿(文中简称冷球)中加入煤可改善球团矿的还原性。为了进一步探索加煤量对冷球性能的影响,在以前实验的基础上进行了配煤比分别为10％、15％、20％、25％的冷球在1000℃的温度下焙烧的实验。
Studies have shown that the addition of coal in cold-solidified pellets (referred to herein as cold pellets) can improve the pellet’s reducibility. In order to further explore the influence of the amount of coal on the performance of the cold ball, experiments were carried out on the basis of the previous experiments. The results show that the cold balls with 10%, 15%, 20% and 25% ration respectively are calcined at 1000 ℃.
