摘　　要：通过对堵塞水口及堵塞物形态的调查，分析了引起水口堵塞的主要原因，并采用了中间包塞棒吹氩技术来预防水口堵塞。工业实验表明，该技术不仅能有效地防止水口堵塞，增加低碳铝镇静钢的连浇炉数。The main reasons for nozzle blocking are analyzed through an investigation of plugged nozzle and morphology of accretion . The nozzle is prevented from blocking by means of argon blowing technique with tundish stopper.Industrial experimentsshow thatthetechnology notonly can efficiently preventthe nozzle block ing andincreasethe numbers ofcontinuouscasting heatsoflow carbon aluminium - killed steel,butalsoimprove steelcleanliness.
