ABB launches new box gauge for aluminum hot rolling mills

ABB extends Millmate Thickness Gauge (MTG) offering for aluminum production with new version for final hot rolling stages.

ABB has launched a new version of its Millmate Thickness Gauge (MTG) technology that brings precise aluminum thickness measurement to the final stages of the hot rolling process. The new MTG Box Gauge extends the proven performance of the MTG technology into hot rolling environments. MTG Box Gauge measures aluminum strip thickness below 8 millimeters at the tail end of hot rolling, where accurate data is crucial for ensuring product quality and production efficiency.

Protection against the demanding conditions encountered in hot rolling processes is ensured by a refined IP66 sealing that shields the interior sensor components from contact with emulsions used to manage friction and control temperatures during rolling.

The new design also features an optimized internal air flow that channels cool air toward heat sensitive electronic boards, while expelling warm air through the base of the unit. This can reduce the operating temperature of the transmitting coil by as much as 40°C, contributing to greater durability and improved efficiency.
