摘　　要：为了了解结晶器内坯壳的生长规律,通过测量漏钢时板坯连铸结晶器内的残留坯壳的厚度,获得了坯壳厚度变化的趋势.测量结果表明,沿坯壳纵向厚度波动无明显规律,厚度波动大,坯壳宽面中心生长比较均匀;沿坯壳的横向波动规律性强,振幅小.坯壳的立体形貌和厚度分布数据给连铸过程数值模拟提供了宝贵的验证依据.In order to understand the growth rhythm of the solidified shell in the mould,the variation trend of solidified shell thickness was obtained by measuring a real breakout residual shell in the mold of the continuous slab casting.Measuring results show that the regularity of the longitudinal wave along the shell is bad and the amplitude is large;the growth of the center shell is more uniform;the transverse fluctuation along the shell has strong regularity and small amplitude.The present data can be used to validate the mathematical modeling of continuous casting process.
