Achenbach OPTIMILL®
Rolling Mills for Copper Brass
Achenbach copper & brass rolling mills reliably produce best strip qualities even at maximum rolling speeds, maximum rolling widths and highest coil weights. In the segment rolling mills they are designed as two- or four-high hot rolling mills, in the segments cold strip and thin strip rolling mills as six- or four-high rolling mills and in the segment of foil rolling mills as six-high rolling mills and thereby always tailored to the specific purpose.
For each new strip rolling mill or those to be modernized, a holistic approach to perfectly synchronize mechanics, hydraulics, automation and drive technology in their complex interaction is applied.

Core Technology
OPTIROLL ® System
The integrated, modulary built rolling mill automation system Achenbach OPTIROLL® i3 is used in all Achenbach OPTIMILL® rolling mills and plays a key role in modernization of existing rolling mills of all brands. OPTIROLL convinces in its integrated approach especially with efficient model-based control functions and open interfaces, comprising the following six control modules.
SUPERSTACK ® Filter
Achenbach filtration systems tailored to the specific operation purpose serve for micro-filtration of the cooling lubricants, such as especially of rolling oil, in a continuous process with customized filter aids.
Together with the Achenbach AIRPURE® exhaust air purification systems and the Achenbach ROILPURE®rectification systems, they handle the entire exhaust air and coolant flow in the rolling process.
Following the closed-loop principle, they operate ecologically as well as economically highly efficient.
OPTIPURE ROILPURE ® System
Achenbach rectification systems thermally separate tramp oils from the rolling oil and redirect the rolling oil into the production cycle in as-good-as-new quality. They are always tailored to the specific operation purpose.
Together with the Achenbach SUPERSTACK® filtration systems and the Achenbach AIRPURE® exhaust air purification systems, they handle the entire exhaust air and coolant flow in the rolling process.
OPTIPURE AIRPURE ® System
Achenbach exhaust air purification systems serve for the energy-optimized separation and recovery of rolling oil from the rolling mill exhaust air. They are always tailored to the specific operation purpose. Together with the Achenbach ROILPURE® rectification systems and the Achenbach SUPERSTACK® filtration systems, they handle the entire exhaust air and coolant flow in the rolling process. Following the closed-loop priciple, they operate ecologically as well as economically highly efficient.
OPTILINK®
The cloud-based platform Achenbach OPTILINK® opens the way to the overall system networking of the various value creation stages and therefore to the optimization of the entire production process.
Integrative Technology
As a system provider, Achenbach follows an integrative approach by offering installation-wide solutions that incorporate multiple individual components. This single source concept lets us design a production process that is optimally tailored to your needs, from rolling to slitting to further processing.
