- Influencing Parameter Study on Primary Breakup of Free Falling Steel Melt Jets Using Volume of Fluid Simulation
Sebastian Neumann, Tobias Dubberstein, Humberto Chaves, Clemens Kirmse and Rüdiger Schwarze
Version of Record online: 25 MAY 2016 | DOI: 10.1002/srin.201500338
The free falling liquid steel jet behavior is numerically investigated using implicit large eddy simulations and the volume of fluid approach. The research focuses on primary breakup phenomena near the nozzle, quantifying the influence of process and constructional parameters. The jet behavior shows distinct inflow and nozzle design dependencies, which influence the jet shape and disintegration into ligaments or droplets.
- Investigation on Improvement of Center Porosity with Heavy Reduction in Continuously Cast Thick Slabs
Zhigang Xu, Xinhua Wang and Min Jiang
Version of Record online: 25 MAY 2016 | DOI: 10.1002/srin.201600061
In order to improve the center porosity of slabs, the heavy reduction process of START (Solidification Terminal Advanced Reduction Technique) is developed. START is implemented with 9 mm heavy reduction in the first segment and 3 mm reduction in the second segment accounting for the uneven solidification. As a result, center porosities along the slab width are significantly improved.
- Mechanical Properties and Transformation Behaviors of Ti–Zr Killed Low-Carbon Steels with High-Temperature Hot-Rolling Process
Chao Wang, Guodong Wang, Zhaodong Wang and Raja Devesh Kumar Misra
Version of Record online: 23 MAY 2016 | DOI: 10.1002/srin.201600057
The experimental low-carbon steels are deoxidized with Ti and Zr to form effective inclusions for intragranular ferrite nucleation. High-temperature hot-rolling process is adopted and coarse prior austenite grains are formed. However, the as-transformed microstructure is significantly refined due to inclusion-induced acicular ferrite formation and, meanwhile, the mechanical properties are also remarkably improved.
- Casting of Fe–CrMnNi and ZrO2-Based Metal–Matrix Composites and Their Wear Properties
Richard Acker, Stefan Martin, Klaus Meltke and Gotthard Wolf
Version of Record online: 19 MAY 2016 | DOI: 10.1002/srin.201500471
A metal–matrix composite of a metastable austenitic–martensitic CrMnNi-TRIP-steel and 14% metastable zirconium dioxide ceramic is produced by gravity fed casting. The infiltration of the porous ceramic foam by liquid melt is increased through additions of sulfur. Its increased wear resistance is examined in a three-body abrasive wear test and compared to other wear materials.
- Prediction of Steady-State Strip Profile in Flat Rolling
Jae Sang Lee, Tae Jin Shin, Sung Jin Yoon and Sang Moo Hwang
Version of Record online: 18 MAY 2016 | DOI: 10.1002/srin.201600032
A mathematical model is proposed for the prediction of the effect of post-deformation on the strip profile in flat rolling. The model's prediction accuracy is examined through comparison with a finite element model. Also examined is the effectiveness of the proposed model, through comparison with actual measurements.
