New Power Coilers for X100 Tubular Steels: Siemens VAI Modernizes Group of Coilers for Severstal in Russia
Severstal is the second largest producer of flat steel in Russia. In the company's hot rolling mill 2 in Tscherepowez in the Wologda district, around six million metric tons of strip steel are produced every year. Modernizing the group of coilers is aimed at expanding the product range, enhancing product quality and, at the same time, increasing both productivity and the availability of the plant.
The central feature of the project is the installation of two Siemens VAI Power Coilers to replace coilers 4 and 5. Thanks to the use of four pressure rollers, of which the first is a dual roller unit, the Power Coiler technology will enable coiling of thick and high strength steels up to X100 tubular steel. Moreover, Siemens will renew the lateral guides of coiler number 4, install a new roller table, including lateral guides, ahead of coilers 5 and 6, and equip coilers 4 and 5 with fully hydraulic drivers and new coil removal carriages. The associated electrical equipment and the automation system are also part of the project.
After modernization of the group of coilers and installation of the two new Power Coilers, the Tscherepowez hot rolling mill will be able to produce strips up to a maximum width of 1,850 mm and thicknesses of between 1.2 mm and 25.4 mm. After the two successful start-ups of Power Coilers at the ArcelorMittal facilities in Fos sur Mer, France, and in Cracow, Poland, this is the third order for this reliable and efficient coiler solution from Siemens VAI.
One important reason why the contract was awarded to Siemens VAI was the close cooperation that has existed between Siemens VAI and Severstal since 20 years. In June this year, Severstal nominated Siemens for the “Long-standing Partnership” award as part of the “Partnership 2008” competition.
