摘要

When blast furnaces (BF) is operated under oxygen enrichment and high PCI rate, H_2, coal preheating and decomposition heat of coal volatile should be taken account as important factors for BF operation line. Based on basic theories, the authors modify calculation and plot methods of BF operation line with no coal injection, deduct calculation formulae and physical meaning of BF operation line with oxygen enrichment and high PCI rate. The modified operation line can be used for quantitatively describing mass balance, heat blaance and the relations among smelting parameters of BF with oxygen enrichment and high PCI rate.
