After the successful installation and commissioning of a 3-roll PSM (Precision Sizing Mill) into an existing bar mill in Pohang early this year, the Korean producer, Hyundai Steel, has granted SMS-group the final acceptance.

The 3-roll precision sizing mill PSM 380/5 supplied by SMS-group will be used to roll purely SBQ grades in the diameter range from 25mm to 83mm onto the existing cooling bed.

The scope of supply of the PSM included the mechanical and electrical equipment, the automation system and the complete equipment for the roll workshop.

According to SMS-group, the PSM is characterised by a highly dynamic hydraulic adjustment of the roll gap. The hydraulic adjustment is controlled by the performance module TCS (Technological Control System) and allows adjustment under load and hence fully automatic rolling of very close tolerances for the automotive industry.

Supplemented by the PSM, Hyundai Steel can now cost-effectively roll any steel grade even in very small lots of different sizes, the SMS-group claims.

With this investment in SMS group's latest 3-roll technology, Hyundai Steel is reacting to the high quality demands of the automotive sector.
