ArcelorMittal has chosen power conversion company Converteam to revamp the electrical and automation systems of its Cold Rolling Mill in Bremen, Germany.

The plant, started up in 1957, is a major producer of hot and cold rolled coils and hot dip galvanized coils for the automotive and other industries.

The first step of the revamp includes the upgrade of the drive and automation & control system of the pickling line, used to produce clean, scale free surfaces, to increase the flexibility of the system.

The second one is aimed at reducing cycle time and intermediate product inventory through the connection of the pickling line to the tandem mill, used to perform the rolling process in a single pass.

The process control system architecture installed by Converteam during the tandem mill revamping in 2005, will serve as the technological platform.

The scope for the 280m-long pickling line includes the feeders and inverters for 26 strip guiding drives as well as the higher-level automation equipment for the sequencing and hydraulic systems.

Process control and sensor equipment together with the safety systems will also undergo comprehensive revamping. With the coupling of the tandem mill to the pickling line,

ArcelorMittal will have a continuous plant for flat steel production by using a consistent process control and management system.
