- Effect of Glaze on the Corrosion Behavior of ZrO2–Graphite Insert of the Submerged Entry Nozzle in the Continuous Casting of Steel
Anup Kumar, Rita Khanna, Muhammad Ikram-ul-Haq, John Spink and Veena Sahajwalla
Article first published online: 14 NOV 2014 | DOI: 10.1002/srin.201400266
This work highlights the importance of compositional control and coating thickness of the glaze material on the ZrO2–graphite refractory insert in submerged entry nozzles (SEN). The degradation of the partially stabilized ZrO2 grains starts during pre-heating itself due to the formation of reaction products. Corrosion in later stages is caused by the fragmentation of the aggregate phase and structural damage.
- Five Ways to Determine the Initial Sheet Width in Bending
Peter Groche and Tilman Traub
Article first published online: 14 NOV 2014 | DOI: 10.1002/srin.201400249
Especially in roll-forming, designers are still challenged by determining the initial sheet width, since many different approaches exist for this calculation leading to different results. This article compares different experimental approaches to determine the initial sheet width and provides a starting point for further studies to improve the calculation methods.
- Reduction Process of Pellet Containing High Chromic Vanadium–Titanium Magnetite in Cohesive Zone
Jianxing Liu, Gongjin Cheng, Zhenggen Liu, Mansheng Chu and Xiangxin Xue
Article first published online: 11 NOV 2014 | DOI: 10.1002/srin.201400212
This paper discusses the softening and melting characteristics, peripheral textures, microstructure of internal core and phase transition of valuable components (Fe, V, Ti, and Cr) of pellet containing high chromic vanadium–titanium magnetite in the cohesive zone of the BF. The Ti(C,N), VN, VC, and FeCr2O4 can be generated in the reduction process.
- Flow and Solidification in Billet Continuous Casting Machine with Dual Electromagnetic Stirrings of Mold and the Final Solidification
Dongbin Jiang and Miaoyong Zhu
Article first published online: 11 NOV 2014 | DOI: 10.1002/srin.201400281
Coupling the electromagnetic field, fluid flow, heat transfer and solidification, a 3D numerical model is developed to simulate the billet continuous casting process of high carbon steel with dual electromagnetic stirrings in the this paper. The calculation results help us to understand the fluid flow and solidification during the strand solidification.
- Improvement of Microstructure and Mechanical Properties of a Low Alloy Cast Steel Processed by Direct Quenching–Partitioning–Tempering Technique
Zheng-Lian Tang, Shan-Shan Cao and Xin-Ping Zhang
Article first published online: 11 NOV 2014 | DOI: 10.1002/srin.201400244
A novel direct quenching–partioning–tempering (DQ–P–T) process is presented and applied to a low-alloy Mn–Si–Cr cast steel. DQ–P–T cast steels have higher volume fractions of the retained austenite than traditional reheat quenching and tempering (RQT) steel, and show the improved microstructure consisting of the dislocation-type lath martensite and nano-sized flake-like retained austenite between martensite laths, which results in enhanced mechanical properties of the cast steel.
