Mold operation with spring suspension and a programmable hydraulic drive is considered. Computer methods of investigating the mold-billet interaction are developed. A new mold with longitudinal-transverse vibration and dynamic stabilization has been developed for continuous-casting machines. © 2011 Allerton Press, Inc.

Selection of the optimal blank in the rolling of profiles with a rhombic cross section may be based not only on the consumption of metal and the rolling force but also on the utilization of the material's margin of plasticity and the profile's margin of stability in rolling. Calculations of four groove configurations permit the identification of the rectangle-rhombus configuration as optimal. The performance of the product is more stable in that case. © 2013 Allerton Press, Inc.

This article examines a system developed to assist decision-making in the control of blast-furnace operation. The system is designed to prevent accidents, improve the qualifications of furnace personnel, and train students in upper-division courses at vocational schools. It was developed on the basis of the principle of heterogeneous modeling, i.e., combining dissimilar models. © 2011 Springer Science+Business Media, Inc.

Electroslag remelting of a high-alloyed steel with high contents of nitrogen, chromium, and manganese in an electroslag furnace has been studied. CaF2-MgO-SiO2 slag developed at TsNIITMASh and allowing remelting process at a temperature of 1520-1560°C is used as a flux. It is found that electroslag remelting of high-alloyed steels with a high nitrogen concentration does not change the nitrogen content. © 2013 Pleiades Publishing, Ltd.

This paper continues the work begun in a previous paper [Eur. Phys. J. B 71, 85 (2009)]. To treat the equations that describe a crystal with condensate that can be superfluid, a method termed the Kirkwood approximation is used. Earlier, the method was found to be rather seminal when applied to a classical crystal. In the case of a simple cubic lattice, solutions to the equations under study can be expressed in terms of the well-known Mathieu functions. A more realistic case of the face centered cubic lattice is also considered although in this case the three-dimensional equations cannot be reduced to one-dimensional ones. Condensate crystals without superfluidity are studied first and then the same crystals in a superfluid state. It is shown in particular that a crystal in which the condensate is formed is energetically preferable with respect to the same quantum crystal without condensate at absolute zero of temperature. Therefore, on lowering the temperature there must somewhere occur Bose-Einstein condensation in the crystal. In the concluding section, we discuss various physical aspects of the problem. © 2010 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

The electroslag remelting (ESR) of the metal wastes of nickel alloys is studied. It is shown that the chemical composition, physicomechanical properties, and service properties of the formed castings meet the requirements of the specifications for these alloys. ESR workpieces are used as a charge for remelting in a vacuum induction furnace according to a standard technology. © 2011 Pleiades Publishing, Ltd.

Methods for calculating the bulk modulus of glasses with homogeneous and heterogeneous structures are proposed within a model that takes account of the different degrees of interaction between structural elements comprising two-component glasses. Lead-silicate and lead-borate glasses are studied as examples of the application of these computational methods. © 2012 Springer Science+Business Media, Inc.

The paper is devoted to the elaboration of a mathematical apparatus for studying second-order phase transitions, both commensurate and incommensurate, and the properties of emerging phases on the basis of the approach in equilibrium statistical mechanics proposed earlier by the author. It is shown that the preliminary symmetry analysis for a concrete crystal can be performed analogously with the one in the Landau phenomenological theory of phase transitions. The analysis enables one to deduce a set of transcendental equations that describe the emerging phases and corresponding phase transitions. The treatment of an incommensurate phase is substantially complicated because the symmetry of the phase cannot be described in terms of customary space groups. For this reason, a strategy of representing the incommensurate phase as the limit of a sequence of long-period commensurate phases whose period tends to infinity is worked out. © 2013 International Union of Crystallography Printed in Singapore-all rights reserved.
