Achenbach OPTIROLL® Automation outstanding performance

Achenbach Optiroll®

Rolling Mill Automation

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.

MORE EFFICIENT THROUGH THE NETWORKING WITH ACHENBACH 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.
