Steel Rolling Mill Gearbox Supply

CMS has recently supplied a set of gearboxes for a steel rolling mill upgrade through our Shackleton Engineering Gearbox Division.

The key objective for the project was to upgrade the gearboxes in the steel rolling mill with the minimum of downtime and disruption to production.

The drive system for the steel rolling mill comprised:

  • 5.5 tonne gearbox for the main coiler rated at 17kW
  • 2.5 tonne gearbox for the slitter rated at 55kW
  • 2.5 tonne gearbox for the shear drive rated at 55kW
  • 0.4 tonne gearbox for the die set drive rated at 62kW
  • 0.2 tonne gearbox for the leveller rated at 200 kW

The gearboxes were all designed to the high quality Case Hardened and Ground gear standard (DIN 3990-5). The external dimensions were specified as direct replacements for existing gearboxes. This was to minimise replacement time and eliminate any foundation work in a production environment.

The gearboxes were manufactured, assembled and fully tested in house before customer inspection and shipping.
