Hulamin Rolled Products

Pietermaritzburg, South Africa

the project

The project involved the design engineering and supply of a new control system and drive converters for the main mill stand and coilers, new AC drives for the shape meter roll, tucking roll and entry pinch rolls as well as those for a new coil prep station.

the solution

The existing ABB PLC used for the drive control was replaced with an AC800M controller and the software rewritten accordingly. Three more AC800M controllers were used for the mill ancillary equipment, Schneider filter and coil handling system, replacing the old Square D PLC. New remote I/O nests were also provided in all operator desks and plant located interface panels, as well as two new motor control centers.

All engineering and design was done by our team in Newport, UK. The new drives suites were built and tested at Newport, whilst all new MCCs, desks and remote I/O nests were built by our subsidiary company, Tiprow Controls, at our Benoni facility. Project management and customer liaison was performed by our South African resident engineers, with regular progress meetings in Pietermaritzburg.

Commissioning was performed by engineers from IAC Newport and after sales support by local and overseas personnel.
