摘　　要：结晶器正弦振动模式下,250mm厚连铸坯振痕深度较深,通过试验3种非正弦振动模式找出了最优的非正弦振动参数。优化后的非正弦振动方式下铸坯振痕深度最小为0.16mm;碳含量主要通过影响钢的高温强度来影响振痕的深度;随着铸坯拉速的提高,振痕有减轻的趋势;结晶器振动方式和参数的选取要综合考虑保护渣消耗等因素。In the mold of sinusoidal vibration, the depth of 250mm slab depth of oscillation marks in thickness is deep, the best non-sinusoidal vibration parameters have been found after testing three kinds of non-sinusoidal vibration modes; the minimum depth of the slab oscillation mark is 0.16 mm under the condition of optimized non-sinusoidal vibration mode. Carbon steel will influence the depth of oscillation marks by influencing the steel high-temperature impact strength;With the increasing of slab casting speed, the oscillation marks will be reduced. The mould power and other factors will be considered for the selection of mold oscillation mode and parameter.
