  • a second arrangement variation provides that in the transport direction of the steel material at least one spray unit roll pair is arranged following a first and a second spray beam pair.
  • a third arrangement variation provides that between the first spray beam pair and the second spray beam pair at least one spray unit row pair is arranged.
