A method is proposed for constructing the profile of the expanded upper working cavity of the mold to allow it to accommodate the pouring nozzle in the casting of thin slabs. A relation is presented to determine the angle of inclination of the narrow faces of the mold. © 2012 Springer Science+Business Media, Inc. Source

A mathematical model is formulated for deformation of a thin slab shell in a mold with a nonlinear internal profile taking account of metal volumetric stressed state and friction between a slab shell and mold surface. Values of axial stresses within a shell and the amount of change in slab broad face size are analyzed. © 2014, Springer Science+Business Media New York. Source

This article examines the main types of surface defects on slabs and their causes. A general explanation is given for the nucleation and growth of surface cracks. An analysis is made of the possibility of applying criteria from the fracture mechanics of deformable solids to the conditions that exist during the continuous casting of steel slabs. © 2012 Springer Science+Business Media, Inc.

The objectives of the study discussed in this article were to analyze production data and construct regression models that can describe the changes in the concentrations of manganese and silicon in reinforcement steel during its treatment outside the steelmaking furnace. The results that are obtained can be used to devise a new technological scheme for the ladle treatment of reinforcement steels at mini-mills. © 2012 Springer Science+Business Media, Inc. Source

Experimental values have been determined for the integral emissivity (blackness) of periclase-carbon refractories used in the working layer of the lining of steel-pouring ladles. The values were found for the range 500–900°C. It was established that the emissivity of periclase-carbon refractories is considerably higher than that of periclase refractories. Use of the data which were obtained is making it possible to more accurately measure the temperature of such linings by the pyrometric method. © 2014, Springer Science+Business Media New York.
