Flexibility and productivity in cold rolling of aluminum
SMS group offers single-stand cold rolling mills for a broad spectrum of aluminum alloys and thin strip and multi-stand tandem cold mills as the solution for a large production capacity. We completed our portfolio of cold rolling mills by the EDT rolling mill, especially designed for rolling and tempering of automotive grades.
EDT rolling
Customized surface properties for automotive sheets
There are extremely high demands on material for exposed car panels. Here, automotive manufacturers insist on excellent formability during pressing and a perfect surface appearance after painting. EDT rolling transfers this exact finish onto the strip during the final rolling pass.

Single-stand cold rolling mill (CRM)
Solutions from the market leader for a wide range of aluminum grades and thin strip
Main dataproducts up to an annual production capacity of up to 200,000 tons. There is nothing to beat the CRM when it comes to hard grades. This mill type rolls a material range from AA1xxx up to AA8xxx series. To suit your specific requirements, you can choose between CVC® plus 4-high or 6-high versions.

Combined reduction and EDT rolling mill
Flexible designs for special applications
There is an ever-growing demand from the automotive industry for aluminum. Highly formable 5xxx-series alloys are mainly used for inner car body parts, whereas 6xxx-series alloys are favored for exposed outer parts. To ensure you meet car manufacturers' requirements, we developed our innovative combined reduction and EDT rolling mill. It's available in single or twin-stand versions.
One great advantage is that Inner car body parts and exposed parts can be processed in the same mill. In EDT mode roughness is transferred onto the strip surface by EDT-machined work rolls during a soft reduction pass using lower rolling forces. The “combo mill” can be flexibly operated either in heavy-force reduction modes or in light-force EDT mode.

Tandem cold mill
Solutions for large volumes of high-quality strip
Main dataAA3xxx and AA5xxx-series aluminum grades are typically used for manufacturing beverage cans. This is where tandem cold mills (TCM) from the market leader offer you the most efficient solution. Operating several single-stand mills doesn't make economic sense, especially if you want a production volume of up to 450,000 t/year. Our tandem cold mills for aluminum are available as two stands, three stands or four stands in CVC® plus design.

Dry strip system (DS system)
Excellent surface quality
Now available to you is our new-generation DS system. It offers you an ideal, contact-free way to remove rolling emulsion residues from strip. What makes this system so highly efficient is that it needs less compressed air.
Installed in the exit of a cold rolling stand, the DS system simply blows cooling lubricant residues off the strip surface. This effectively prevents stain spots. High productivity is the hallmark of our latest-generation DS systems. That's due to the optimum combination of stationary and movable sealing elements as well as precisely balanced blow-off and extraction areas. One of the core components of the DS system is the wear-proof and contactless sealing of the roll barrel. This is also known as a COANDA nozzle.
