采用旋转桨吹氩，将吹入钢水中的氩气泡破碎成微小气泡，并均匀分布在钢水中，使氢、氧随氩气泡浮出，达到脱氢、脱氧的目的。本文主要研究各种因素对精炼钢水脱氢率、脱氧率的影响。结果表明：在本实验条件下，精炼２～３ｍｉｎ，脱氢率为５０．０７％，脱氧率为４８．５０％，脱硫率为４６．２０％；氩气流量和旋转枪转速最佳值分别为０．２５～０．２８ｍ３／ｈ和４２０ｒ／ｍｉｎ；另外，精炼效果与精炼时间呈正比关系。
Adopting rotary paddle to blow argon, the argon bubble blown into the molten steel is broken into tiny bubbles and uniformly distributed in the molten steel, so that the hydrogen and oxygen emerge with the argon bubble to reach the purpose of dehydrogenation and deoxidation. This article mainly studies the influence of various factors on the dehydrogenation rate and deoxidation rate of the molten steel. The results show that under the experimental conditions, the optimum conditions are as follows: refining 2 ~ 3min, dehydrogenation rate 50.07%, deoxidation rate 48.50%, desulfurization rate 46.20%; argon flow rate and revolving speed 0.25 ~ 0.28m3 / h and 420r / min; In addition, the refining effect and the refining time is proportional to the relationship.
