Achenbach OPTIROLL®
Automation 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 6 control modules.
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.
