- 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.
- Effect of Magnesium Addition on Behavior of Collision and Agglomeration between Solid Inclusion Particles on H13 Steel Melts
Gang Du, Jing Li, Zhong-Bing Wang and Cheng-Bin Shi
Version of Record online: 14 JUL 2016 | DOI: 10.1002/srin.201600185
The formation sequence of MgO · Al2O3 cluster is the same as that of alumina cluster, but the MgO · Al2O3 clusters cannot form the outside branch and attract more distant particles. The collision, agglomeration and growth of inclusions, as well as the formation of clusters in H13 steel can be effectively impeded by the adding of magnesium.
- Early Stages of Cu Precipitation in 15-5 PH Maraging Steel Revisited – Part II: Thermokinetic Simulation
Georg Stechauner, Sophie Primig and Ernst Kozeschnik
Version of Record online: 11 JUL 2016 | DOI: 10.1002/srin.201600085
The authors investigate the Cu-precipitation and two DSC peaks in 15-5 PH steel by the means of thermokinetic modeling. The simulations indicate that the exothermic reactions come from the nucleation of Fe-rich Cu clusters and their subsequent transformation into pure Cu composition. The findings support the experimental findings of part I.
