Cutting of coils into sheets
Nova Trading S.A. has opened a service centre dedicated to processing stainless and galvanized steel and aluminium.
The CTL line cuts metal coils into sheets of non-standard length. Manufacturers using steel or aluminium sheets, can order sheets of varying lengths according to their needs, which, by minimising waste, reduce the costs of production. The lead time for non-standard material are also reduced. Nova Trading S.A. delivers metal sheet with non-standard dimensions within one week.
The CTL line cuts s coils with a weight of up to 25 tonnes, thickness ranging from 0.3 to 3.0 mm and a width ranging from 400 to 1,600 mm. The maximum speed of operation is 60m/min. The sheets produced have a length ranging from 400 to 6,700 mm. The smallest size cut is 400 x 400 mm. The tolerances guaranteed are ± 0.25 mm.

Straight angels while cutting
The line has several additional facilities to increase the quality of the final product, including ensuring straight angles while cutting.
Flatness
One of the most important factors determining the quality of the sheets cut is their flatness. To ensure flatness, not only do we need to straighten the steel coil, but we also need to remove internal tension from the material, which is of paramount importance in the later treatment/processing. For instance, details cut by laser off a sheet from which internal tensioning has not been removed become deformed after cutting, or lose their shape during cutting, which makes processing impossible. FIMI, based on years of experience, constructed its own leveller, which ensures that the parameters of the material cut are perfect.
Protecting the surface of the sheet from damage
The quality of the surface of steel or aluminium sheet is essential for many customers. Any scratches or marks render the material useless for many applications. FIMI’s – CTL has several solutions for protecting the surface of the sheet against damage at every stage – from the moment that the sheet is unfolded, through the transportation of steel sheet, right up to its final positioning on the pallet. To reduce the risk of surface demage, FIMI – unlike other producers – changed the technology of coil cutting, removing the so-called ‘loop’ which is seen as the line’s critical point.
