摘要

摘要采用四分之一尺度的水模型实验，研究了单孔和双孔塞的放置和吹送流量对混合时间、渣眼面积和夹渣深度的影响。结果，当吹风流量大于180L时 min–1，双吹塞的吹制效果优于单吹塞。双吹塞布置中的开孔面积和夹渣深度小于单吹塞布置。一般情况下，当吹塞布置在0.4R位置，两个吹塞之间的角度为120°时，钢包精炼效果更好。最终推荐的吹氩工艺为240–300 L 加热和合金化过程的最小值为1，60–120 L min–1分别用于软吹气过程。

Process optimization of bottom-blown argon for 130t ladle furnace

ABSTRACT A quarter scale water model experiment is employed to investigate the effect of single and double porous plug placement and blowing flow rates on the mixing time, slag eye area, and slag entrapment depth. As a result, when the blowing flow rate is greater than 180 L min–1, the blowing effect of double blowing plugs is better than that of single blowing plugs. The open eye area and slag entrapment depth in the double blow plug arrangement are smaller than that in the single blow plug arrangement. In general, the ladle refining effect is better when the blow plug is arranged at 0.4R position and the angle between the two blow plugs is 120°. The final recommended argon blowing process is 240–300 L min–1 for the heating and alloying process and 60–120 L min–1 for the soft blowing process, respectively.
