- Effect of Oxygen-Coal Lance Configurations on Coal Combustion Behavior
Zhenfeng Zhou, Hailong Huo, Guang Wang, Qingguo Xue, Xuefeng She and Jingsong Wang
Version of Record online: 22 AUG 2016 | DOI: 10.1002/srin.201600197
A three-dimensional coal combustion model is developed to simulate the lance–blowpipe–tuyere-raceway of a blast furnace. The coal flow and combustion behaviors are investigated under different oxygen enrichment ways of oxygen-coal and oxygen-coal double lances. The burnout is very different under different oxygen enrichment ways. The increase in the coal burnout is very obvious under special local oxygen enrichment ways.
- Usefulness of Non-Uniform Heating and Quenching Method for Residual Stress of Bimetallic Roll: FEM Simulation Considering Creep Behavior
Nao-Aki Noda, Kejun Hu, Yoshikazu Sano, Katsma Ono and Yusuke Hosokawa

The residual stress is investigated for bimetallic roll after non-uniform heating and quenching in comparison with the one after uniform heating and quenching. The usefulness of non-uniform heating quenching is discussed for reducing the risk of thermal barrel breakage. In this FEM simulation, the effect of creep on stress relaxation is also considered.
- Influence of Cr2O3 and B2O3 on Viscosity and Structure of High Alumina Slag
Ren Ze Xu, Jian Liang Zhang, Zhi Yu Wang and Ke Xin Jiao
Version of Record online: 17 AUG 2016 | DOI: 10.1002/srin.201600241
The viscosity of slag containing 2 wt% Cr2O3 and 1 wt% B2O3 is similar to the viscosity of Cr-free and B-free slag, which indicates the viscosity increment resulted from the addition of 2 wt% Cr2O3 can be eliminated by adding 1–2.5 wt% B2O3. So the addition of B2O3 can reduce the viscosity and improve the fluidity of Cr2O3-containing slag.
- Characterization of MnS Particles in Heavy Rail Steels Using Different Methods
Xuewei Zhang, Lifeng Zhang, Wen Yang and Yuanchi Dong
Version of Record online: 17 AUG 2016 | DOI: 10.1002/srin.201600080
The morphology of MnS changed from elliptical and spherical near the surface of bloom to strip-like, petal-like, polyhedral, and irregular in the center of bloom gradually. The size of both pure MnS particles and complex inclusions which consisted of a MnS outer layer and an oxide core increased from the edge to the center of bloom.
- Numerical Simulation of Supersonic Oxygen Jets at High Ambient Temperature
Ziliang Li and Daqiang Cang
Version of Record online: 12 AUG 2016 | DOI: 10.1002/srin.201600209
The applicability of existing two-equation turbulence models has certain limitations on simulating supersonic jet at different ambient temperatures. The standard k–ϵ model and the realizable k–ϵ model are applicable to the simulation of supersonic jet at room temperature. Meanwhile, the standard k–ω turbulence model is superior to the other models when simulating the supersonic jet at high temperature.
