A new water-air system for the secondary cooling of slabs on a continuous caster in the electric steelmaking shop at Ural Steel has been developed and introduced on the basis of an analysis of the operation of the caster as a whole. New schemes were devised for the locations of the manifolds and nozzles, the water distribution system, mixers, and nozzles were redesigned, and new secondary cooling regimes were instituted. Introduction of the new system for the secondary water-air cooling of slabs has made it possible to expand the production of special steels and improve the quality of the slabs' surface and macrostructure. © 2011 Springer Science+Business Media, Inc.

This article examines slag-forming mixture (SFM) feed regimes that provide for effective lubrication in continuous-caster molds and reduce the stresses in the skin of the continuous-cast semifinished product. It is shown that use of the mold oscillation regimes developed by the KORAD Corporation solves these problems and ensures dynamic balancing of the substantial loads that act on the structural elements of the caster during the vibration of massive molds. © 2011 Springer Science+Business Media, Inc.

The research reported here was directed toward saving thermal energy during the heating of steel semifinished products prior to their shaping. The research examined the use of temporary protective coatings that reduce oxidation losses of the metal, the degree of decarbonization of the semifinished products, and the rate of rejection of the finished rolled products for rolled-in scale. It was determined experimentally that use of the coatings increases rather than decreases the efficiency of the heating operation. It is shown that it is possible to save fuel by using coatings of the type described in the article. © 2011 Springer Science+Business Media, Inc.

The design of the secondary-cooling system of a continuous slab caster in the electric steelmaking shop at Ural Steel is analyzed. Defects in the slabs are studied and the effect of secondary cooling on the surface defects and macrostructure of the slabs is determined. Thermal calculations are performed of the slab crystallization process, and it is found that the existing design of the secondary-cooling system makes it impossible to use the caster to cast high-strength tube steels or ship plate. Technical recommendations are made for modernizing the system. © 2011 Springer Science+Business Media, Inc.

This article examines the warming of steel in a tundish during the continuous casting of grades of steel that are used in critical applications. The authors examine how the introduction of an organic addition to the powdered slag-forming mixture affects its thermal conductivity. Quantitative relations are obtained to describe the dependence of the thermal conductivity and bulk density of the mixture on its content of rice husks. A comparative analysis of the warming properties of heat-insulating mixtures used at the leading Russian combines and powdered assimilating mixtures containing rice husks shows that the latter can be used without additional insulation. © 2013 Springer Science+Business Media New York.
