Research on Preparation of Direct Reduction Oxidized Pellets for Hydrogen-rich Shaft Furnaces
The gas-based shaft furnace process in the steel industry has high requirements for the quality of pellets. In order to reduce the import volume of high-quality iron concentrate and thus lower the production cost of high-quality pellets for gas-based shaft furnaces, domestic high-grade iron concentrate is finely ground to improve its fineness, and is used in combination with high-performance composite bentonite while the process of pellet roasting is well controlled, which can produce high-quality pellets that meet the requirements for direct reduction in gas-based shaft furnaces.
