When metal melt is discharged into the ladle, the metal surface is constantly renewed, on account of the fluxes that form. Calculations show that the manganese formed in direct alloying may modify the surface layer of the metal melt. (In certain conditions, sulfides are formed thanks to the sulfur dissolved in the metallic melt.) The efficiency of this process increases with increase in ladle radius and the discharge time, since the depth of the active zone declines. © 2011 Allerton Press, Inc.

Magnetic diagnostics of the working layer on rollers is considered. A diagnostic method is proposed on the basis of the coercive force (the residual magnetization of the material) and employed by means of the robotized Valok 2000 diagnostic complex. The diagnostic results are presented in graphical and numerical form, by means of charts of roller properties. The basic approach to interpretation of the magnetic charts is outlined. Sample charts are presented for rotors with various defects. The potential of magnetic diagnostics in intake and periodic monitoring of the rollers is demonstrated. The stability of roller manufacture and subsequent roller operation may be assessed by this means. The results permit the identification of rollers with problems, reduction in the accident rate, and optimization of roller preparation. © 2011 Allerton Press, Inc.

On the basis of the relation between magnetic and lattice degrees of freedom, it is of interest to consider a special structured state with spatial scale of the order of tens of nm at the beginning of polymorphic γ-α transformation in steel. Supercooling of this state leads to the formation of disperse structures that are stronger and harder than bainite and pearlite and more plastic than martensite. © 2010 Allerton Press, Inc.
