Abstract
The performance of coke could significantly impact the permeability of a deadman in a blast furnace (BF). The poor permeability of the deadman would increase the flow rate of molten iron near the carbon brick and increase the temperature of the carbon brick. In this paper, the relationship between the production parameters of a 3200 m3 BF and the lining temperature in a hearth was studied based on the Pearson correlation coefficient. The research results indicated that the main factor affecting the lining temperature in the hearth was the proportions of dry quenched coke (DQC) to wet quenched coke used. When the proportion of DQC used increased, the lining temperature decreased after approximately 95 to 120 days. The results could be used to expand our understanding of the mechanisms by which the lining temperature of BF hearth could be reduced and the BF service life could be prolonged.
