Change in Oxidizing and Reduction Roasting of Complex Iron-Titanium Ores

Abstract:

The questions of oxidizing roasting of iron ore raw materials with production sinter and pellets are considered. The question of reduction roasting of iron ore raw materials is studied. Phase transformations of oxidizing and regenerative roasting are considered. Features of phase transformations of iron ore raw materials containing titanium are discussed. The reducibility, durability and temperatures of softening and melting of metallurgical iron ore raw materials are studied In Vitro. The effect of the durability of burned iron ore pellets on compression is also defined.
