Primary- Secondary Descaling and Hot Roller Table

Customer: Salzgitter Mannesmann Grobblech GmbH

The existing primary and secondary descaling systems, including their hot roller conveyors, had to be replaced.


The aim of renewing the high-pressure descaling system is to optimise the descaling effect. The hot roller tables were replaced due to their wear condition.

The slabs are placed on the curved roller conveyor by means of the new removal unit, then transported to the primary scale scrubber, centred and descaled as they pass through. Finally, they are transferred onto the existing TM wagon.
