Dummy Bar-kop voor continugieten
The dummy bar-kop is installed at the front end of the dummy bar and positioned at the lower part of the gietvorm. It provides the initial connection between the dummy bar and the newly solidified staal strand during casting start-up. A properly designed head must match both the gietvorm section and the dummy bar connection.
Dummy Bar-kop Doorsnedes
Casting sections in our production range. Final head dimensions, connection dimensions and tolerances are confirmed against the op maater's gietmachine drawing.
