Mastery of the Production of Slag-Forming Mixtures at the Nizhniy Tagil Metallurgical Combine

A shop has been organized at the Nizhniy Tagil Metallurgical Combine to make slag-forming mixtures and a factory standard has been developed for its products. The quality of the mixtures is fully consistent with the requirements established for mixtures used in the continuous casting of steel. The mixtures reliably insulate the meniscus of the metal in the mold and provide the necessary degree of lubrication between the skin of the solidifying ingot and the walls of the mold. The technology used to prepare the mixtures makes it possible to change over from one type of slag-forming mixture to another without stopping production. __________ Translated from Metallurg, No. 4, pp. 42–43, May, 2005.     

Steelmaking and Rolling at the West Siberian Metallurgical Combine

Removing scale from the surface of wire rod before it is drawn is an important operation that affects the structure, mechanical characteristics, and commercial properties of the rod. The West Siberian Metallurgical Combine has worked with the Russian-Bulgarian consortium Ékomet to develop and introduce integrated lines WCM-05 and SCM-07 (for coiled rod) and SCM-02 (for uncoiled rod) to mechanically remove scale. The lines have several advantages over similar existing equipment: they can be installed directly in line with the draw bench; the scale can be removed by a combination of several methods; the installation costs are lower than for comparable facilities.
