摘要:

通过气肥煤、肥煤与其他单种煤的共结焦试验,考察了二者的改质作用,试验结果证明肥煤改质作用优于气肥煤。在此基础上进行了气肥煤替代部分肥煤的捣固炼焦试验,结果表明在保持配合煤黏结性稳定的前提下,焦炭的反应后强度随着气肥煤替代量的增加先增大后减小,焦炭反应性的变化趋势与之相反,而焦炭的冷态强度随着气肥煤替代量的增加变化不大。

Abstract:

The modification effect of gas-fat coal and fat coal was studies through common coking test mixed with these two kinds of coals and other single coals.The test result shows that the modification effect of fat coal is better than that of gas-fat coal.Based on the test,stamp charging experimentation with gas-fat coal instead of partial fat coal was carried out,which indicated that on the premise thatcaking property of blending coal is stable,as increasing amount of replacing gas-fat coal,coke strength after reaction first increased and then decreased,but the change of coke reactivity index was in the opposite way,and the coke strength in cold condition changed little.
