Abstract：The successful implementation of canceling central coking charging in Taisteel No.1 BF was summarized. The emphasis was on the specific method of canceling the central coke charging. It was considered that in order to successfully cancel the central coke charging, ensuring the good active state of the hearth before implementation was the foundation, the improvement of the raw fuel quality was the guarantee, and the optimization of the operation system of the upper and lower parts was the key to realize the smooth conversion of the gas flow. Through a careful and detailed plan in the early stage, the operation parameters were revised in time by closely following the change of gas flow in the process of implementation, and the central coke charging was successfully canceled at one time, without the slider, collapse, suspension, slag peeling and other furnace condition fluctuation. The results showed that the dead coke heap of the hearth becomes smaller after canceling the central coke charging, which played an important role in improving the hot metal circulation and reducing the sidewall temperature of the hearth, and at the same time, the utilization of blast furnace gas was increased and the fuel ratio was reduced.
