振动痕一直是影响冷轧产能发挥及成材率稳定的一个主要原因。
Vibration marks are always a major cause that greatly affects the yield stability and capacity expansion of a cold rolling mill.
施加高频电磁场的铸坯与传统连铸坯相比，表面振动痕深度明显减小，且表面光滑。
Compared it with conventional billet, billet cast with high frequency electromagnetic field, on which depth of surface oscillation mark was decreased remarkably, had a smooth surface.
相反，普通连续铸造锭表面因存在振动痕和亚表面偏析等铸造缺陷，力学性能大大降低。
On the contrary, the surface imperfections, such as oscillation and subsurface segregation etc, found in DCC ingot, cause the mechanical properties drop largely.
阐述了轧机处于第三种类型振动时，铝箔表面产生振痕的原因。
The cause of producing vibration track on the aluminium foil surface is explained, when the mill works in the state of third type vibration.
