In order to establish the evaluation method of coke quality in the blast furnace, it is important to investigate the coke degradation behavior in the furnace.
From this point, the sampling of coke was done during the shut-down at three levels-lower shaft, bosh and tuyere. The degradation behavior of coke and the mutual correlation between the coke properties and operational conditions were investigated. From the operational results of the blast furnace, the degradation behavior of coke at the lower part of the blast furnace and the relation between the blast conditions and degradation degree of coke were discussed.
