Effect of Iron Ore Size on Kinetics of Gaseous Reduction

Autor: Takeaki Murayama, Heung Won Kang, Won Sub Chung

Publikováno v: ISIJ International. 38:109-115

In order to investigate the size effect on the kinetics of the gaseous reduction of iron ore, two kinds of iron oxide pellets of different diameters were reduced with CO-CO 2 gas mixture. Results were analysed using two models, Ishida-Wen's model and

Ishida-Wen's Model for Non-spherical Particle

Autor: Won Sub Chung, Takeaki Murayama, Heung Won Kang, Yoichi Ono

Publikováno v: ISIJ International. 38:1304-1310

Thiele's modulus for non-spherical particle is assumed by introducing the concept of non-spherical radius. Based on this modulus, Ishida–Wen's model for non-spherical particle considering the shape effect is presented. An example of the application

Effect of Iron Ore Shape on Gaseous Reduction Rate

Autor: Heung Won Kang, Won Sub Chung, Yoichi Ono, Takeaki Murayama

Publikováno v: ISIJ International. 38:1194-1200

In order to clarify the effect of particle shape on the gaseous reduction rate of iron ores, iron oxide pellets of various shapes including the long cylindrical- and the disc shape are reduced with 10%CO-90%CO2 gas mixture. Experimental results show

Gas-Solid Reaction Model for Non-spherical Iron Oxide

Autor: Won Sub Chung, Yoichi Ono, Heung Won Kang, Takeaki Murayama

Publikováno v: ISIJ International. 38:324-331

Iron oxide pellets of various shapes are reduced from hematite to magnetite with CO-CO 2 gas mixture to investigate the shape effect on the gaseous reduction rate of an iron oxide pellet. Based on the observation result of the section of partly conve
