Abstract: A multi-fluid blast furnace model was used for the numerical simulation of some innovative ironmaking technologies to evaluate how the relevant operations affect blast furnace process and production indices. Those new ironmaking technologies included injecting hydrogen-bearing materials for hydrogen-enriched reduction, charging CCB for low-temperature ironmaking and recycling top gas to enhance the utilization of carbon and hydrogen. The simulation results of the model revealed that the application of those new technologies will bring the blast furnace process to super-high-efficiency operation, i.e. high productivity, lower energy consumption and lower CQ2 emission.
