中间包塞棒吹氩技术的应用
APPLICATION OF ARGON BLOWING TECHNIQUE WITH TUNDISH STOPPER
-
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,而且还可改善钢质。Abstract: 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 experiments show that the technology not only can efficiently prevent the nozzle blocking and increase the numbers of continuous casting heats of low carbon aluminium-killed steel, but also improve steel cleanliness.
