Shishimirov M.V. et al. Melting Steel in an Arc Furnace to Increase Production Efficiency
There have been presented and proposed techniques aimed at enhancing the technical-and-economic indices of melting carbon and high-alloy steels in a 10-ton arc furnace by:

  • reducing waste of metal by feeding cooling medium onto the bath surface inside the electrode disintegration circle, which lowers the metal evaporation intensity (cooling medium components are specified);
  • forced mixing of metal, which reduces the time of electric arc action and increases the yield, reduces the specific electric energy and electrode consumption per ton of melt;
  • using maximum transformer capacity over the entire melting with screening electric arcs in a foamy slag layer to reduce the negative influence on the walls' lining.

  • The above-mentioned measures allow to increase the yield of a single melting by 0.5%, reduce the specific electric energy and electrode consumption, and obtain an economic effect in melting both carbon and high-alloy steels.

    Dzhandieri G.V. et al. Enhancing Durability of Troughs of Ferroalloy Casting Machines
    There have been developed methods of enhancing the durability of troughs of ferroalloy casting machines, which allow prolonging the operation life of troughs by 20% on average. The proposed alternative technical solution is also an effective method of improving such process parameters as casting rate and performance. The proposed methods can be used for manganese, silicon and chromium ferroalloys of virtually any grade and not only for conveyer-type casting machines, but also for carrousel-, screw-type semicontinuous and rotary continuous casting machines.

    Modern Materials

    Kabaldin Y.G. et al. Neuronet Modeling in Synthesizing Stable Nanosystems
    In the last years, nonomaterials and nanotechnologies have been considerably developed. There has been formed a new interdisciplinary line- nanomaterials science, the main objective of which is the creation of materials with predetermined properties. The important tasks being solved by that line include the determination of the nanoparticle (NP) size variation limits, in which the stability of nanosystems' structural state is maintained.

    Muravyov S.N. Application of Wavelet Analysis to Predict Fatigue Strength of Materials
    Nowadays, a trend of increasing demands on both structural materials and methods of evaluating their strength in real-time mode is observed. Such an approach suggests expansion of our conceptions of the nature of strength and mechanisms of destruction of materials, evaluation of their structural stability. This is possible only by using modern physical methods of investigation. One of such methods is the digital processing of acoustic emission signals of a dynamic materials system (wavelet analysis), emerging during their deformation and destruction, and in investigating the material deformation process during fatigue testing. The wavelet analysis is being used in many fields of science and technology: for image identification, numerical simulation of dynamically complex processes and others.

    Kuznetsov A.A. et al. About Possibility of the Study Structured Characteristic Material by Spectral Analysis Methods
    In work is considered possibilities of the checking material facility by atomic-emission spectral analysis expansion. Perspective directions connected with the possibility of the checking the structured particularities material and product, defining their physics and mechanical characteristic.
    For decision of the checking structured parameters and physics and mechanical characteristic problems is designed physical model of the spectral radiation source, linking measured parameters with under investigation. There is considered insulated and balanced checking systems for standard and investigation sample comparatively for the experiment conditions.
    The results of the study different structured parameter and physics and mechanical characteristic are given on example aluminum alloy samples with equal chemical composition. The given results are confirmed by traditional methods of investigation parameter testing.

    Semyonov V.I. Solidification and Growth of Nano-, Micro- and Macrocrystals in the Flow of Melt Being Cooled
    Natural (without forced mixing) development of phase transformation of pure substances, eutectics, hypo- and hypereutectic alloys in the flow is set forth. It is shown how the mechanism of melt solidification, localizing the thermodynamic driving forces in the macro areas of the flow, self-organizes the phase processes. As the macro areas with concentration and heterogeneous boundaries move with the flow, forces of particles' kinetic energy had to be engaged, and their role in local atomic rearrangements to be evaluated and determined.
    Studying of the principles of self-organization of phase processes opens a way to development of new schemes of combined technological impacts on the solidifying melt to produce billets with a desired structure and a predetermined set of properties.
