  Pelletization and sintering of New Zealand titanomagnetite …

  2022121 · This study reports an investigation of the pelletization and subsequent sintering behaviour of titanomagnetite (TTM) ironsand, which is the main iron ore feedstock for New Zealand’s steel industry. Initially green pellets were bound with bentonite and carboxymethyl-cellulose (Peridur), using an average ironsand particle size of 65 µm.

  An efficient method for iron ore sintering with high-bed …

  2021423 · Poor permeability and low sintering productivity restrict the development of high-bed sintering. An efficient method of the double-layer sintering process (DLSP) was proposed to achieve high-bed sintering and solve the aforementioned problems. Theoretical calculation and sintering pot experiments were implemented to investigate the double …

  Strengthening Granulating and Sintering Performance of Refractory Iron ...

  2023330 · May Concentrate Iron ore, as a refractory iron concentrate, deteriorates the permeability of the sintered layer during the sintering process due to its fine particle size and poor granulating performance. Therefore, it cannot be widely used in iron ore sintering. In this study, the strengthening granulation of May Concentrate Iron ore using pre-pelletizing …

  EVOLUTION AND GROWTH OF IRON ORE …

  201511 · Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction processes.

  Study on Sinter Iron Ores and Titanium Ores Used in Pelletizing

  2021217 · In this paper, study on sinter iron ores and titanium ores used in pelletizing was carried out. Bond work indexes of different sinter iron ores and titanium ores were measured. Ballability would be improved, and falling strength and compression strength of green pellets would be increased after fine-grinded sinter iron ores have been added.

  CO<SUB>2</SUB>-Free Flux for Sustainable Iron Ore Pelletizing

  The iron and steel manufacturing sector directly accounts for 7-9% of global CO 2 emissions. Raw material preparation, such as iron ore sintering, pelletizing, and cock making, is the major CO 2 emitter. As climate change becomes a bigger concern, steel manufacturers need to lower CO 2 emissions without hindering efficiency or increasing costs.
