In order to increase the proportion of pellets putting into the furnace and reduce the amount of blast furnace slag and fuel consumption, through laboratory tests and industrial tests, the flux and production process parameters that are beneficial to the production of low-silicon alkaline pellets are studied. The results show that slaked lime has good bonding properties, which is conducive to reducing the proportion of bentonite used in the pellets, and has less decomposition and heat absorption, which has little effect on the compressive strength of the pellets, and can realize the production of high-quality low-silica alkaline pellets, while it can meet the requirements of high ratio of blast furnace. After Shougang Jingtang three 5 500 m³ blast furnaces are equipped with high-quality and low-silicon alkaline pellets, the total pellet ratio increased from the original 28% to 55% ,and the CO₂ emissions per ton of iron is reduced by 10%.
