在总结国内外炼焦配煤控制方法的基础上 ,确定了宝钢焦炭强度预测和配煤煤质控制方法的基本思想 ,构筑了一种新的预测焦炭强度的参数CCI。根据试验获得的数据 ,采用多元逐步回归进行了焦炭强度的预测 ,宝钢焦炉焦炭的DI1 501 5 、CRI和CSR的预测值与实测值有着很好的相关关系 On the basis of summarizing the control methods of coke blending at home and abroad, the basic idea of ​​predicting the coke strength of Baosteel and the control method of coal blending quality is established, and a new parameter CCI for predicting the coke strength is established. Based on the data obtained from the experiments, the multivariate stepwise regression was used to predict the coke strength. The predicted value of DI1 501 5, CRI and CSR of Baosteel Coke Coke has a good correlation with the measured values
