Article first published online: 20 JAN 2015 | DOI: 10.1002/srin.201400237
This work is focused on investigating burden descending behavior in a new-design COREX shaft furnace. The effects of operational parameters on solid flow pattern are examined. The influence of Areal Gas Distribution (AGD) beams on burden descending behavior is also evaluated. The investigation reveals that the AGD beams affect the solid flow significantly and lead to poor adaptability of furnace to abnormal operations.

A torsional vibration model of rolling mill main drive system driven by salient pole synchronous motor is established with the electromechanical coupling effect taken into account. The periodic solutions of the strongly nonlinear torsional vibration system are obtained by using the IHB method. The effects of different electrical and mechanical parameters on the system amplitude-frequency property and vibration displacement characteristics are analyzed.

Knowledge based approach to designing power plant steels calls for accurate information on high temperature phase & microstructural stability. In the present study, Dynamic Calorimetry, Electron Microscopy, together with Thermodynamic Simulations, have been carried out to rationalize the observed high temperature phase phase transformation behaviour of W and Ta added Reduced Activation Ferritic Martensitic (RAFM) Steel.
- Characterization of Low Cycle Fatigue Performance of New Ferritic P92 Steel at High Temperature: Effect of Strain Amplitude
Xiaowei Wang, Jianming Gong, Yanping Zhao, Yanfei Wang and Minghao Yu
Article first published online: 20 JAN 2015 | DOI: 10.1002/srin.201400246
Influence of strain amplitude on the low cycle fatigue behavior of P92 steel is studied. Continuous cyclic softening can be divided into three stages. Prediction of the low cycle fatigue life is performed based on a modified life prediction model and the newly adopted lifetime end criterion. The stress-strain hysteresis loops at different strain amplitudes are also modeled based on time-independent cyclic plasticity model.
- Interaction Between Deformation-Induced and Thermal Martensite in High-Manganese TRIP Steel
Haiyan Yang, Jing Li and Ping Yang
Article first published online: 8 JAN 2015 | DOI: 10.1002/srin.201400297
In-situ observation and EBSD reveal the interaction of deformation-induced and thermal martensite which is manifested by the formation means of deformation-induced α′-M. Two means exist: nucleation in the intersection of two thin ε-M plates and direct growth of existing thermal α′-M in thick ε-M plates. Good content consistency exists between thermal and deformation-induced martensite which quantitatively demonstrate the interaction between the two.
