摘　　要：围绕结晶器流场变化对铸坯质量的影响,从结晶器流场入手,重点分析了振动、浸入水口、塞棒吹氩、保护渣、结晶器液面波动对结晶器流场的影响,通过采取一系列措施,减少了铸坯在结晶器内形成的缺陷问题,铸坯纵裂纹明显减少,降低了生产成本。Based the influence of flow field change in mold on casting billet quality,it is analyzed in emphases the influences on flow field caused by vibration,immersion nozzle,stopping bar argon blowing,protecting slag,liquid surface change.With a series of measures adopted the defect of billet formed in mold is reduced,longitudinal cracks obviously reduced and cost got lower.
