Abstract
In order to improve the thermal properties of coke, an industrial experiment on the coke spraying with ZBS additive solution was carried out at coking plant and No. 6 blast furnace (2 000 m3) of Kunming Iron and Steel Co Ltd. The coke reaction index (CRI) of the coke spraying with ZBS additive solution decreases by 10. 56%. and the coke strength after reaction (CSR) increases by 7.80% in comparison with those of the un-sprayed coke. During the experiment, the average iron output increases by 66. 69 t/d, and the coke rate is reduced by 5.21 kg per ton iron, while the fluctuation of furnace temperture is small, and sulphur content in hot metal and 100% of hot metal are acceptable.
