SMS Demag AG, Germany, has received from Ural Steel AG (Uralskaya Stal), Novotroitsk, Russia, an order for the modernization of its electric steelmaking plant for long and flat products with the aim of increasing the annual capacity from 0.75 to 2.0 million tons of quality steel.
Ural Steel is investing altogether around 300 million US Dollars for the modernization of the production units at the Novotroitsk location.
Through this comprehensive investment program, Ural Steel wishes to move away completely from old methods of steel production and invest in production units which will enable more sophisticated steel grades to be manufactured, which will then be able to be further processed into high-quality products in the downstream rolling mills.
The order comprises the modernization of the steel plant, of the continuous caster and of the downstream rolling mill. The first modernization stage was implemented already in 2004 with the commissioning of a continuous slab caster, built by SMS Demag, followed by the order for an electric arc furnace, including a process computer, at the beginning of 2005.
The supply scope of the order awarded in July 2005 includes a 120-t electric arc furnace equipped with change-vessel technology, a dust collecting facility, modernization of the existing bin system and the engineering for the hot-metal charging equipment.
For the extension of the secondary metallurgy facilities, a new 120-t ladle furnace is to be supplied, along with a swiveling electrode-arm system, two stationary covers for two independent treatment positions, and the technological equipment.
The supply scope also includes the four-strand continuous bloom caster, which can optionally cast rectangular sections in the dimensions 330 x 470 mm or round sections in diameters between 430 and 600 mm. The continuous caster is equipped with hydraulic resonance oscillation and with only one type of stirring coil. This can be utilized for all section sizes cast.
SMS Demag will be supplying the complete electrical and automation systems, including Level 2, for the above mentioned core components.
Concurrently, SMS Demag has received an order to modernize the existing rolling mill 2800 which, in the final extension stage, is designed for an annual production of 1.25 million t. The supply program initially comprises new furnaces, a two-high stand, a four-high stand, the quenching facility and the leveler.
The commissioning will be completed in mid-2007.
70 % of Ural Steel’s output is concentrated on the Russian market and the firm produces high-quality tube and pipe grades for the natural-gas and oil industries, for bridge construction and for heavy mechanical engineering.
SMS Demag AG forms part of the Metallurgical Plant and Rolling Mill Technology Business Area of the SMS group.
