Tandem cold mills for aluminumCold Rolling
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.
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.
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.

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.
The Integrated Maintenance Management System (IMMS) is a combination of a CMMS software and valuable data based on decades of SMS experience. From elaborate analyses and existing documents, SMS creates a plant specific, customized package of component- related maintenance strategies for technically and commercially effective maintenance.
IMMS® - steps required for a complete maintenance system
The Genius Condition Monitoring includes a modularly designed, permanent online monitoring system. It controls and records the current condition of wear-prone plant components and notifies when situations become critical.
1. Monitoring of toothing
(Gear mesh frequency) MDVA - Diagnostic Vibration Anaysis
2. Bearing damage
3. Gear unit lubrication
(Dirt particles, oil flow, water level) HDM - Hydraulic Monitoring
4. Spindle monitoring
(Torque) TAS - Torque Analysis System
5. Process monitoring
MiDaS - Mill Diagnostic System
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.
