To reduce coke consumption in blast furnace ironmaking, this study proposed a new method of applying iron-coke briquette prepared using and hematite powder and pulverized coal to protect coke in BF iron making. Results showed that, with a ratio of hematite to coal of 2.0, the iron-coke briquette could obtain a satisfying compressive strength of more than 1500N both before gasification and after being gasified by CO2 for 1h. The activation energy of the iron-coke briquette was 93-135kJ/mol, which is lower than the coke and therefore could protect the coke in BF. The agglomeration and stratification of iron particles occur in the course of iron-coke briquette gasification and is beneficial to the improvement of the iron-coke briquette strength.
