Abstract On the basis of laws of momentum and mass conservation of liquid flux, a mathematical model to represent the liquid friction force in meniscus under non-sinusoidal oscillation was established, and a new liquid friction mechanism was proposed by solving extremum equations of liquid friction force as 2.0 m•min-1 casting speed. The results show that liquid friction force was mainly influenced by the shape of flux channel, depth of molten flux pool and relative motion between oscillating mold and strand and varies with oscillation waveform. Maximum liquid friction force occurs nearby the moment of oscillation velocity equal to casting speed under an ideal state. Surface cracks formed in the positive strip time adjacent to negative strip time, and healed during the negative strip time.
