The DYNAFLEX oscillator, a technology breakthrough in billet casting

This paper describes the first industrial application of the new DYNAFLEX o scillator developed by VAI on the two billet casting machines at Lech-Stahl werke (Germany). Its main features are no servohydraulic components, a syst em of leaf-springs arranged in cascade, simplicity of adjustment of stroke, frequency and wave form during casting. These factors suppress the need fo r maintenance of the oscillator, prevent mechanical backlash and result in a significant increase in machine availability and product quality, as well as in reduced maintenance costs.
