- Attraction Force Estimations of Al2O3 Particle Agglomerations in the Melt
Changji Xuan, Andrey V. Karasev, Pär Göran Jönsson and Keiji Nakajima
Version of Record online: 26 JUL 2016 | DOI: 10.1002/srin.201600090
The influences of van der Waals force, wettability, and solid phase sintering are systematically studied for the Al2O3 agglomeration. A function of Hamaker constant of liquid iron changes with surface tension, which is pointed out. The difference between cavity bridge force and van der Waals force is smaller than seven times.

The microstructure and texture evolution between Cu-bearing and Nb-bearing silicon steel is compared. The mainly grain growth inhibitors in Cu-bearing and Nb-bearing silicon steels are CuMnS and NbCN, respectively. The results indicate that the pinning strength of Nb-particles is much stronger than Cu-particles, and the Goss zone (Region II) in Nb- bearing hot rolled sheets, which act as the nuclei for secondary recrystallization is reduced. Therefore, the magnetic properties of Nb-bearing silicon steel are inferior, compared to Cu-bearing silicon steels.
- The Oxidation and Decomposition Behavior of Carbonate Iron Ore
Yating Tang, Mansheng Chu, Jue Tang, Lin You and Zhenggen Liu
Version of Record online: 20 JUL 2016 | DOI: 10.1002/srin.201600129
In this work, the preoxidation part of a new beneficiation process for carbonate iron ore is studied by the single factor experiments. Besides, X-ray diffraction analysis and scanning electron microscopy are used to investigate the main phase and structure transformations during the oxidation. Meanwhile, through thermoanalysis, the thermal decomposition kinetics of carbonate iron ore are also conducted for this processing.
- A Theoretical Scaling Equation for Designing Physical Modeling of Gas–Liquid Flow in Metallurgical Ladles
Shan Yu, Zong-Shu Zou, Lei Shao and Seppo Louhenkilpi
Version of Record online: 19 JUL 2016 | DOI: 10.1002/srin.201600156
In the present work, a theoretical scaling equation embodying liquid density and surface tension is deduced by analyzing the governing equation of plume rise velocity for physical modeling of gas–liquid flow in metallurgical ladles. The advantage of the scaling equation is demonstrated by comparing the calculated order of prototype gas flow rate with the one based on measured gas fractions.
- Generating Mechanism of Large Heterogeneous Carbonitrides with Multiple Layers in H13 + Nb Bar
You Xie, Guoguang Cheng, Lie Chen, Yandong Zhang and Qingzhong Yan
Version of Record online: 14 JUL 2016 | DOI: 10.1002/srin.201600119
A great number of micron-sized precipitates exist in H13 + Nb bar. These precipitates include oxide cores and outer carbonitrides. The carbonitride can be further classified into Ti–V-rich one, Nb-rich one, and V-rich one. These large precipitates are generated in liquid steel during solidification. The generating mechanism can be well speculated by Thermo-Calc and be helpful to further control.
