Hydraulic model investigation was conducted by using compressed air to simulate the bet-tom-blown argonstirring process of LFV 40 ladle refining furnace.
用压缩空气模拟氩气搅拌，对LF V - 40型钢包精炼炉底吹氩气工艺进行水力学模型实验研究。

Vacuum denitrogenation and bubble carrying denitrogenation are mainly influenced by vacuum, argonstirring, oxygen and sulphur concentrations in liquid metal.
真空度、氢气搅拌和金属液中氧、硫浓度是影响真空脱氮和气泡携带法脱氮的主要因素。

Via experiments and testing on site, the fact that argon absorbs heat during heating is considered to have very little influence on temperature drop of molten steel during stirring by blowing argon.
