【Abstract】 In this paper, the mould electro hydraulic servo oscillation control system with digital wave occurer is introduced. Compared with the traditional equipment, the system can easily adjust the oscillation wave according to the continuous casting technique and adjust the parameters of frequency and magnitude.The control precision is improved and the automation level of continuous casting is enhanced. The study indicates the system frequency range can reach 12 Hz and can satisfy the needs of the continuous casting prodution更多还原
