Resumo
Mannesmann Demag has developed a new continuous casting mould featuring a unique suspension system for the water jackets using leaf springs. This innovation eliminates the need for the conventional mould table. The use of leaf springs enables play- and wear-free articulation, resulting in a tenfold improvement in guiding accuracy and a significant reduction in strand friction. Additionally, the stress on the drive system is reduced due to 100% compensation of inertia loads. Dynamic performance is further enhanced by reducing the oscillating masses, allowing the full potential of the servohydraulic drive to be realized. For the first time, high-frequency, small-stroke, non-sinusoidal oscillations can be reliably controlled. This new concept ensures: excellent surface quality improved microstructure near the strand edges reduced crack sensitivity increased operational safety better accessibility easier maintenance and operation and, importantly, creates the conditions for higher casting output.
