高炉喷煤对焦炭质量的要求及改善焦炭质量的途径

Requirement of BF PCI for coke quality and ways to improve coke quality

高炉喷煤对焦炭的质量要求是:M_(40)>83％,M_(10)<7％,CRI<28％,CSR>60％,平均粒度50mm。为了满足高炉大喷煤量对焦炭质量的要求,可以采用配煤技术、装炉煤预处理技术和干熄焦技术来提高焦炭质量。

The requirement of BF for coke quality is getting higher with the increase of coal rate. To improve coke quality, the following techniques can be adopted : coal matching, coal pretreating and dry coke quenching .
