| Abstract: | The present paper reviews the research on the mechanism of formation of the oscillation marks on the surface of the slabs in the process of continuous casting and introduces the key model depicting the mechanism of oscillation mark formation and discusses inter-action between the pitch and depth of the oscillation marks and analyzes various factors affecting the depth and pitch of the oscillation marks. Results show that the oscillation marks can be alleviated by appropriately changing the processing parameters in the process of continuous casting and applying the magnetic soft - contact continuous casting technology simultaneously so as to control the surface quality of the slab. |
