Tandem cold mills for aluminum

Cold Rolling
High productivity in aluminum strip production

Aiming to produce just short of half a million tpy of aluminum cold strip? Then tandem cold mills (TCM) from SMS group are the most efficient option for you. Designed in 4-high or 6-high configurations, they feature our well-known CVC® plus as well as other cutting-edge rolling technologies. Here you will experience the latest developments in cooling, strip-edge control, and roll bending to ensure excellent strip quality and profitable operation. Also available to you are highly advanced filter and exhaust air purification systems that meet even the strictest environmental regulations.

TCM - The most efficient solution

AA3xxx and AA5xxx-series aluminum grades are typically used for manufacturing beverage cans. This is where tandem cold mills (TCM) 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 400,000 tpy. That's why there is high market demand for TCM with two to four stands in CVC® plus design.

Solutions for combined reduction and skin pass / EDT rolling

There is an ever-growing demand from the automotive industry for aluminum. You can fully exploit this market with SMS group solutions. 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.

Coating technologies for rolling mills

Chrome plating of work rolls for longer service life

Chrome plating of work rolls

Chrome is one of the hardest metals, with excellent corrosion resistance and a low frictional coefficient. This combination turns the surface of work rolls to high-value and wear-resistant. SMS provides automated coating and carefully inspects the roll before and after chrome plating.

SMS uses EDT prior to chrome plating

Deformation behavior and appearance of the varnish depend on the structure of the strip surface. EDT (electric discharge texturing) is a machining process which removes particles from a work roll surface by energy of electric discharges. The electro-erosion leads to a higher number of peaks on the roll material's surface. This results in a roughness higher by 2-3 points compared to shot-blast-texturing (SBT). In combination with a 0.005 to 0.015 mm thick chrome layer, EDT is a successful solution for automotive sheets.

X-Roll® Oil Bearing

Hydrodynamic roll-neck bearings from SMS group are highly advanced and elementary components of modern rolling mill technology. That's because they support the load-bearing backup rolls. Even under extremely tough operating conditions, they ensure long roll service life and minimal maintenance outlay. This is how roll-neck bearings contribute substantially to meeting the high requirements for optimal final strip geometry.
