Achenbach OPTIMILL® ALUMINIUM strip rolling mills

Achenbach strip rolling mills reliably produce best strip qualities even at maximum rolling speeds, maximum rolling widths and highest coil weights. Designed either as 6-high or 4-high rolling mills they are always tailored to the specific operation purpose. Special applications, e.g. as bright rolling mills, require the 2-high rolling mill design. 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.

The outstanding performance is achieved by automation with Achenbach OPTIROLL®.

The Achenbach OPTIPURE® Media Systems for economically and ecologically efficient exhaust air purification, rolling oil filtration and rolling oil rectification complement the machinery for an optimum rolling process.

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.
