In 2013 FATA Hunter, Division of FATA S.p.A. (a Finmeccanica Company) was awarded a contract for the supply of a 2m wide cold rolling mill and a tension leveling line to Eurometal S.A., Stalowa Wola, Poland. The equipment is being installed on schedule at a greenfield plant located in the new Kleszczów Industrial Parkin Poland.
All the equipment for this new plant has been selected on the basis of its design to make the facility one of the most modern, efficient and environmentally friendly aluminum rolling plants in Europe. The mill features controls that allow it to roll a wide variety of products from foil stock to can body with tolerances that meet or exceed the quality from leading producers.
Eurometal is currently a leading European supplier of aluminium extrusions. The company belongs to the Eko-Swiat Group - a major Polish producer of extrusion billets, primary and secondary alloys, produced through continuous casting technology.
Main characteristics of rolling mill
The rolling mill is designed for the production of strips made from aluminium alloys of the 1 xxx, 3xxx, 5xxx, 6xxx and 8xxx groups, in widths up to 2100mm and in the thickness range 0.15 to 7.0mm starting from hot rolled or continuous cast strips with a maximum thickness of 10mm.
The rolling of continuously cast strip requires different knowledge than the rolling of hot rolled strip. Specifically, a high reduction on the initial rolling passes is necessary in order to remove the oxide layer and smut from the cast strip surface and thus produce high quality strip. This is critical if foil is to be produced downstream in the future and defects are to be avoided. Accordingly, FATA Hunter supplies cold rolling mills with a high rolling torque capability and the work rolls are sized accordingly in order to transmit this high torque. Similarly, the company's mills have coolant filters with a large surface area in order to accommodate the higher coolant dirt loading caused by the removal of these oxides.
The rolling mill has been designed with a maximum speed of 1200m/min, with single drive motors for the mill and...
