- 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.
- Conventional and Tailored Mn-Bearing Alloying Agents for the Production of High Manganese Steels

Concerning the industrial production of high manganese steel melts, conventional Mn-bearing alloying agents are reviewed. A modified process route for pyrometallurgical winning of special silicomanganese grades tailored for high manganese steelmaking has been conceived. For each individual process step, namely manganese slag production, silicomanganese production, and optional desiliconization of silicomanganese, results of lab-scale experiments are discussed.
- URANS Simulation of Continuous Casting Mold Flow: Assessment of Revised Turbulence Models
Christoph Kratzsch, Klaus Timmel, Sven Eckert and Rüdiger Schwarze
Article first published online: 20 AUG 2014 | DOI: 10.1002/srin.201400097
A time resolving numerical model of a single-phase mold is formulated in the frame of Reynolds-averaged Navier–Stokes (RANS) simulations. Thereby the performance of various turbulence models is evaluated focusing the jet flow. The results show, that it is necessary to have higher order discretization with either the RNG k–ϵ model or the k–ω SST model.
- Research and Application of Ultra-Fast Cooling System and Velocity Controlled Strategy for Hot Rolled Strip
Zhen-Lei Li, Hai-Jun Li, Guo Yuan, Guo-Dong Wang and Xue-Qiang Wang
Article first published online: 19 AUG 2014 | DOI: 10.1002/srin.201400077
Ultra-fast cooling is an advanced technology in hot rolling strip for development of low-cost and high-performance steels. Key components, sequential control structure, and mathematical model for ultra-fast cooling are described. Velocity controlled strategy for each strip element is developed. The temperature fluctuation affected by velocity variation is effectively eliminated and the system realizes accurate temperature control of UFCT and CT.
