Achenbach OPTIMILL® ALUMINIUM HOT ROLLING MILLS

Achenbach hot rolling mills reliably produce best hot strip qualities even at maximum rolling speeds, maximum rolling widths and highest coil weights. They are designed as single-stand reversing hot rolling mills, as hot rolling lines with single-stand reversing roughing mills and finishing mills and hot rolling lines with single-stand reversing roughing mills and multi-stand tandem finishing 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.

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.
