【摘要】 利用物料平衡方程、热平衡方程和多元线性回归,计算出热损失,从而实现对焦比的预测。并通过分析建立的热损失与其生产参数之间的线性关系,深入讨论了生产参数与热损失的相关程度与该预测模型的可靠性、精确性和扩展性。研究发现,采用分区域计算热损失的方法,可以在入炉配料等生产参数发生较大变化时,保持该模型预测焦比的准确性。更多还原

【Abstract】 Adopted quality balance equations,heat balance equations and multiple linear regression,heat loss can be figured out and thus the prediction of coke rate can be fulfilled.By analyzing the linear regression relationship established between the heat loss and the production parameters,the correlation of the two has been discussed deeply and the reliability,accuracy and expansibility of the model have also been studied.Investigation shows the accuracy of the coke rate prediction in the model can be ensured by using sub-region methods to calculate the heat loss in case of charge composition and other production parameters changing.更多还原
