| Abstract: | Some distinct and transient phenomena that occur simultaneously during the initial stage of solidification influencing oscillation mark in the vicinity of meniscus are analyzed in detail. The mechanism of oscillation mark formation and factors affecting the formation of oscillation mark are discussed in the paper. The results show that the oscillation mark can be alleviated by comprehensive consideration of continuous casting parameters and applying non-sinusoidal mold oscillation technology to improve the quality of the slab. |
