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.

Results are presented from mathematical modeling of the deformation of a thin slab in a continuous-caster mold with a conical cavity. The objective is to deform the slab in such a way that the free gap between the slab and the narrow wall of the mold changes linearly with a change in casting speed. It is established that the convexity formed in the central part of the slab's broad face may still be present on the slab when it leaves the mold. A process which involves compression of the slab is examined as a means of eliminating the residual convexity. © 2014 Springer Science+Business Media New York.

Rapid development of world automobile manufacture, and before the start of the 21st century failure of domestic automobile sheet steels to keep pace with the world level, determine the importance of carrying out this work. Manufacture of a new generation of more than thirty automobile sheet steel grades has opened up for domestic metallurgical enterprises. Engineering re-equipment of enterprises, use of original scientific approaches based on controlling precipitation of nonmetallic excess phases, comprising a solid solution and grain boundaries, and forms of impurities present, make it possible to develop highly efficient resource-saving technology providing the best set of mechanical properties with minimum expenditure. © 2014 Springer Science+Business Media New York.

A mathematical model has been developed to describe the cooling of steel in a pouring ladle as the steel is held in the ladle prior to its treatment on a ladle-furnace unit. The adequacy of the model is demonstrated, and calculations of the cooling of steel in a ladle are performed. It is shown that preheating ladle linings to 1400°C with the use of electric heaters is a cost-effective measure. © 2012 Springer Science+Business Media, Inc.
