Effect of Ti–V Magnetite Concentrate Pellet on the Strength of Green Pellets and the Quality of Sinter by Composite Agglomeration Process (CAP)

The composite agglomeration process is one of the most potential methods to effectively produce blast furnace burden with vanadium-titanium magnetite. In this work, effects V–Ti magnetite particle size, coke breeze ratio green pellets, pelletized feed, and feed basicity on quality CAP products were studied. results shown that drop strength compressive pellets are improved when pretreated by high-pressure grinding roll compared those prepared from raw material. With increase flux permeability mixed layer sinter yield increase. When 0.9, economic technical indexes sintering best. After finely powder for adding prepare carbon-containing amount should be controlled at about 0.4 mass%, considering compression pellets,. However, containing 0.4% in core produces perforated or molten pellets. Therefore, it not recommended use pellet.
