Cold rolling mills for aluminum

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.

It's a huge challenge to avoid excessive tension at the strip edge during aluminum strip cold rolling. The conventional solution is the hot edge spray (HES) method of heating the work roll barrel. New on the market, our inductive edge heating system reduces strip tension. That ensures faster rolling speeds at lower energy consumption and higher efficiency.

Essentially, the principle behind our inductive edge heating system is an alternating magnetic field that induces eddy currents to generate heat directly on the roll surface.

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. It's above all the European car industry which relies on surfaces with isotropic roughness. EDT rolling transfers this exact finish onto the strip during the final rolling pass.

Crucial here is a specific roughness on the work rolls created by electric discharged texturing (EDT). Once it is applied to the roll barrel, this roughness transfers precisely onto the strip surface. Using EDT rolls ensures the required quality and durability of the color coatings on the exposed parts. The EDT rolling stand is highly versatile. That's because it applies high rolling forces for reduction passes, as well as low rolling forces. So you can achieve various production schedules.

It's important to clean the polluted exhaust air from aluminum and non-ferrous cold rolling mills. Ideal for this job is our Airwash^TM exhaust air purification system. This ensures clean exhaust air and cuts your overheads by recovering the rolling oil so you can use it again.

Inevitably, some of the rolling oil evaporates during aluminum cold rolling. The best way to manage these vapors is to channel them into our Airwash^TM system. Here, they pass through separation elements where washing oil filters out the oily components. Next up, the rolling oil and washing oil are further separated in a rectification process. This is how our Airwash^TM system separates drop-like and gaseous particles from the air. Then you can recycle this valuable resource. The system comprises two sections, one for exhaust-air purification, and one for washing-oil recovery. We also supply Airwash^TM 300 oil specially formulated for use in Airwash^TM exhaust-air purification systems.

Here is a well-balanced and eco-friendly filter technology for your premium-quality cold rolling mill: the SMS group Multi-Plate^® filter.

Our compact Multi-Plate^® filters efficiently clean lubricants contaminated during cold-rolling aluminum and nonferrous metals. You benefit from a modular design that consists mainly of an unwinding device for the filter paper, filter plate stacks, and a filter paper take-up device. First, we prefabricate the components, then assemble them to create your customized Multi-Plate^® filter. Once it's completed, we thoroughly test the filter system over several days. That involves simulating your entire filter process. We run through, test, and optimize every single cycle.
