  1. Experimental Study on the Refining Desulfurization Slag Made from the Reduced Red Mud

    Dong Kai, Wu Long, Liu Wenjuan and Zhu Rong

    Article first published online: 2 SEP 2014 | DOI: 10.1002/srin.201400181

    Refining desulfurization slags made from the reduced red mud are studied by thermodynamic simulation, orthogonal experiments, and verification experiment. The results of the optimal combination slag with the best desulfurization and the metal Fe separation from the reduced red mud prove that, manufacture refining desulfurization slag is a feasible method on the disposal and recycling of the red mud.

  2. Optimization of Midrex Direct Reduced Iron Use in Ore-Based Steelmaking

    Kaisa Huitu, Mikko Helle, Hannu Helle, Marko Kekkonen and Henrik Saxén

    Article first published online: 2 SEP 2014 | DOI: 10.1002/srin.201400091

    The potential of using direct reduced iron as a partial substitute of pellets in a blast furnace is studied. The main objective is to analyze the prerequisites for an economically feasible operation of a steel plant integrated with a direct reduction plant. The results illustrate the conditions under which it will be economical to use DRI in the blast furnace.

  3. Dissimilar Metal Active Gas Welding of TWIP and DP Steel Sheets

    Pasquale Russo Spena, Paolo Matteis and Giorgio Scavino

    Article first published online: 1 SEP 2014 | DOI: 10.1002/srin.201400154

    New austenitic high-manganese TWIP steels have been proposed for the fabrication of car-body components, due to their excellent combination of strength and ductility. A widespread usage of TWIP steel grade is conditional on the employment of resistance spot welding to assemble body components made of dissimilar steel grades. For this reason, this work aims at investigating the mechanical and microstructural response of dissimilar butt weld seams of TWIP and dual phase steel sheets, with an austenitic filler, made by MAG welding.

  4. Influence of the Sulfur Content on the Sintering Behavior and the Mechanical Properties of a CrMnNi-TWIP-Steel

    Sabine Decker, Katja Lange, Lutz Krüger and Tobias Dubberstein

    Article first published online: 1 SEP 2014 | DOI: 10.1002/srin.201400141

    Sulfur reduces the surface tension of steel melts and enables the generation of very small steel particles during gas atomization. Results show, that high-alloyed steel with sulfur contents in the range of 0.02–0.1 wt% exhibits a high strength and a good deformability under quasi-static compression despite the formation of a large fraction of sulfur precipitations.

  5. Applicability of Top Gas Recycle Blast Furnace with Downstream Integration and Sequestration in an Integrated Steel Plant

    Rajeev Kumar Sahu, Sanat Kumar Roy and Prodip Kumar Sen

    Article first published online: 22 AUG 2014 | DOI: 10.1002/srin.201400196

    Global warming has led to consideration of the top gas recycle (TGR) blast furnace with significant potential to reduce CO2 emissions. A TGR system model has been developed to simulate the behavior of TGR furnace under different operating conditions. Under optimal conditions, the estimated total carbon requirements can be brought down substantially. But simultaneously there is a considerable reduction in the available downstream energy as well as an increase in sequestration load.
