A Commercial Production Test of Iron Ore Sinter Using High Amounts of Pisolite Ores and Quality Evaluation of the Sinter Products

摘要

To utilize pisolite ores as raw materials of iron ore sinter, a commercial production trial was carried out by designing the structure of quasi-particles. Main results obtained from the trial are summarized as follows: (1) The commercial production test using 40 mass/100 pisolite ores in raw materials showed that high Quality sinter was produced by making quasi-particles having duplex structures; the inner core is granulated By raw materials containing the pisolite ores and the outer shell is coated with both coke fine and high Grade magnetite ore fines.
