Abstract: Based on the hydraulic oscillator of slab continuous casting test platform, displacements and other parameters of hydraulic oscillator were measured. Displacements differences and phase differences at different oscillating parameters were studied, and the characteristics of non-sinusoidal waveforms were discussed. The results show that hydraulic system, which performs sinusoidal and non-sinusoidal oscillation, oscillates smoothly and can obtain high oscillating precision. The hydraulic oscillators demonstrate the advantage and potential for application in mould oscillation.
Key words: continuous casting; mould; hydraulic; non-sinusoidal oscillation
