Monitoring of the energy consumption in an arc smelting furnace when using various materials permits the optimization of the batch composition. To this end, the corresponding multicriterial optimization problem is analyzed, and a method is proposed for determining the energy-saving batch composition. This method consists of six main steps, including the following: collection and organization of the technological information; plotting of cause-and-effect diagrams; and description of the electrical consumption by means of a multicriterial optimization problem containing a system of constraints with empirical coefficients. © 2014 Allerton Press, Inc.

Theoretical and technological principles have been developed for the plastic deformation of the surface layer, with simultaneous application of a metal coating, by means of a flexible tool. This process is known as frictional plating. Resource-saving and environmentally benign technologies have been created for the manufacture of metal components with improved performance. © 2011 Allerton Press, Inc. Source

The selection of blast-furnace batch is considered. Software is developed for the calculation of the blast-furnace batch in forced startup (with controllable slag formation and reduction). In this approach, the first portion of slag-forming mixture and iron ore is introduced in the furnace shaft, and there is no need for gradual increase in the ore load. The software permits the compilation of reference material (the design characteristics of the blast furnaces, the parameters of preceding melts, the properties of the slag-forming mixture and iron ore, the properties of the coke, etc.); calculation of the batch composition and the properties of the hot metal and slag with specified additions of slag-forming mixture and fluxes and specified blast parameters; calculation of the optimal batch composition and selection of the blast parameters within the constraints on the thermal, slag, and gas-dynamic parameters and the quality of the hot metal produced; diagnostics; and presentation of the calculation results in tabular and graphical form, with subsequent storage in a database. © 2015, Allerton Press, Inc.

The surface microtopography of auto-industry sheet passed through rollers whose surface has undergone various kinds of treatment-shot blasting, electric-discharge texturing, electron-beam texturing, and TOPOCROM treatment-is compared. The amplitude and frequency parameters of the surface roughness are also compared, as well as the correlational, spectral, and fractal characteristics of the surface microprofile. It is shown that the microrelief of the sheet is best after TOPOCROM treatment and electron-beam texturing of the rollers. © 2010 Allerton Press, Inc. Source
