  1. Corrosion Behavior of Al2O3-C Refractories with Casting Mould Meniscus Slags at 1 550 °C

    Anup Kumar, Rita Khanna, Mohammad Ikram-ul-Haq, John Spink and Veena Sahajwalla

    Article first published online: 19 MAY 2015 | DOI: 10.1002/srin.201400590

    Several randomly oriented needle-like growths are observed in the upper interfacial region of Al2O3-15 wt% graphite substrates after contact with slag 1 for 7 min indicating the establishment of a compositional gradient within the slag mass. The lower interfacial region of long duration corroded sample (30 min) is composed of Al2O3 granules and reduced compounds composed of Mn and Si.

  2. Inclusion and Microstructure Characteristics in Steels with TiN Additions

    The present work provides a quantitative study of inclusion and microstructure characteristics in the steels with TiN additions. The effect of inclusion size on the probability of IGF nucleation in the present samples is mainly focused to be discussed. This figure shows a binary image of the typical microstructure containing intragranular ferrite and grain boundary ferrite in this work.

  3. Wrinkling during Cup Drawing with NUMISHEET2014 Benchmark Test

    The figure shows the simulated wrinkling profiles for AA5042 with NUMISHEET2014 Benchmark Test. A total of 13 wrinkles are generated consistently for both experiment and simulation. Finite element model contains 57 721 nodes and 57 540 four-node BWC shell elements based on an explicit time integration method. Barlat's Yld2000-2d material model is employed with isotropic hardening.

  4. CFD-DEM Study of Heat Transfer in the Reduction Shaft of Corex

    Qinfu Hou, Jian Li and Aibing Yu

    Article first published online: 12 MAY 2015 | DOI: 10.1002/srin.201400367

    Corex is a promising iron making process beside blast furnace. Using a combined approach of computational fluid dynamics and discrete element method transient heat transfer of gas–solid flow in reduction shaft of Corex is investigated. The effects of discharge rate and burden profiles are discussed. Useful information for the scaling of a discrete particle model is provided.

  5. Transferring Characteristics of Momentum/Energy during Oxygen Jetting into the Molten Bath in BOFs: A Computational Exploration

    Article first published online: 7 MAY 2015 | DOI: 10.1002/srin.201500034

    Transferring characteristics of momentum/energy during oxygen jetting into the slag–metal molten bath in BOFs are studied by a multi-fluid VOF model. The evolution of the momentum/energy and turbulence of jets along their axial travel are analyzed, and the efficiency of the momentum/energy transfer from the jets to the molten bath is assessed with respect to lance height and operation pressure
