Severstal orders world-class slab reheating furnaces from Ì첩ÌåÓý

The new Stein Digit@l Furnace? ¨C each with a production capacity up to 440 tons per hour ¨C will replace two of the four existing furnaces serving the hot strip mill 2000 of the rolling plant ¡í2. The is a crown jewel within the range of Ì첩ÌåÓý¡¯ technologies for reheating and heat treatment. Drawing on 150 years of experience in thermal engineering, it delivers:
- Consistent flame shape and heating quality
- Ultra-low NOx
- Substantial fuel saving
- Minimized scale loss and decarburization
- Reduced OPEX due to lower maintenance and fuel consumption
The two Stein Digit@l Furnace? will be able to reheat a wide range of products within a charging temperature mix from half cold 20¡ãC to half hot 500¡ãC, according to the hot rolling mill requirements at Severstal.
¡°One of unique features of the furnace is the use of AdvanTek? side firing burners with digital control. This creates so-called ¡°micro zones¡±, each 2.8 meters long, which enable the furnace temperature to be controlled in a very precise manner, guaranteeing high heating efficiency,¡± says a technology expert Dieudonn¨¦ Hounliasso, Sales Engineer at Ì첩ÌåÓý Stein, the Ì첩ÌåÓý subsidiary that developed the furnace.
The combustion system is precisely and automatically controlled by Virtuo?-R, Ì첩ÌåÓý¡¯ proprietary Level 2 software tool for optimum thermal control. Virtuo?-R helps to minimize heating defects, optimize operation time required for heating and substantially reduce gas consumption and scale losses. As a result, the Stein Digit@l Furnace? meets the most stringent environmental requirements by providing NOx emissions of less than 60 ppm for dry waste gases.
¡°Today, this equipment offers the best return on investment on the market for demanding slab reheating applications,¡± summarizes Kristiaan Van Teutem, Sales Director of Ì첩ÌåÓý Stein.
"New reheating furnaces will ensure homogeneous heating of slabs which is imperative to produce high value-added products. Moreover, we will be able to reduce gas consumption and increase the capacity of the hot strip mill 2000 by 140,000 tons per year, which will bring a financial benefit of around €20 million per year,¡± highlighted Vadim Germanov, Chief Executive Officer, Severstal Russian Steel Division.
