Non-Sinusoidal Oscillation of Mould Based on Hydraulic Oscillator

Based on the measurement of the continuous slab caster in Baosteel,some characters of non-sinusoidal oscillation in hydraulic oscillation system of mould were tested and analyzed.The characteristics of non-sinusoidal curve as well as the variation of oscillator driving force were discussed under the conditions of different deviation angles.For the inverse oscillation setup of drawing speed-frequency,the parameters such as negative strip time were calculated and analyzed under the conditions of sinusoidal and non-sinusoidal oscillations,and the friction forces of mould were also discussed.The results indicate that the non-sinusoidal oscillation can optimize the technological parameters,which suits the high-speed slab continuous casting and it is better than the traditional sinusoidal oscillation.
