Application of Tamping Coke on Large-Scale BF Smelting

Abstract:

At present, domestic and international large-scale blast furnace applications of tamping coke is still in its exploratory stage. Part of the BF applications tamping coke, there are some problems, including high-temperature zone upward, feeding speed slows , air flow along edge enhancement and heat exchange being inadequate. Through analysis of tamping coke combustion performance and the effects of tamping coke on the material column permeability, The following measures are suggested; using a suitable charging system to open center airflow, stable gas distribution, combined to increase the oxygen-rich rate, increasing the amount of wind, improving coal injection rate. The stable operation of BF is realized, hot metal increased and coke conserved.
