Reconstruction of vertical continuous lab casters–An optimum solution for astering the production of flat-rolled products for critical applications

Existing vertical continuous casters have outlived their normal service life of 30–35 yrs, and they are physically worn out and technically obsolete. This limits the possibilities for using them to cast metal that goes into products intended for critical applications (thick plates, ship plate, skelp for gas and oil pipelines, etc.). However, there are several technical and technogical innovations that could be used to rebuild these units. One example is the reconstruction of the vertical caster used by Severstal’ to cast slabs in its electric steelmaking shop. Severstal’ itself, the Korad Corporation, and the company Ormeto-YuUMZ were the main organizations involved in the design, rebuilding, and startup of the modernized caster. __________ Translated from Metallurg, No. 5, p. 60–62, May, 2006.     

Continuous slab-casting of steel in Russia

The production of cast slabs in Russia is reviewed, and means of improving continuous casting are proposed.     

Analyzing the performance of the secondary water-cooling system of a single-strand continuous slab caster in the electric steelmaking shop at ural steel

Metallurgist - 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...     

Efficient lubricant supply to molds in continuous-casting machines

Software to provide information on continuous steel casting is based on a rheological model of the system consisting of the mold, the lubricant, and the casting. Using this software, the most effective mold configurations and parameter ranges may be selected; their influence on factors such as the formation of the mold surface and the resistance to steel passage through the mold may be investigated; and the supply of slag-forming mixture may be optimized.     

Heat-insulating slag-forming mixture for tundishes for the casting of a wide range of steels

New heat-insulating slag-forming mixture P-4 has been developed and introduced for casting different sizes of semifinished products composed of a wide range of steels. The mixture has low contents of fluorine and carbon and contains additions of organic agricultural wastes. __________ Translated from Metallurg, No. 2, pp. 48–50, February, 2007.
