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.
