Numerical Study on Effects of Molten Steel Flow about Different Blowing Argon Position in Ladle Furnace
Based on momentum theorem, principle of mass conservation, and some experimental formulas, the distribution of velocity in ladle furnace was calculated by CFD methods. Blowing argon arrangement in ladle furnace is researched, through comparing 13 schemes about blowing argon arrangement, some conclusions are obtained. When there is only a blowing argon in ladle furnace, the better scheme is that the distance from center of LF bottom to the hole is 0.7r. When there are two blowing argon in ladle furnace, the better scheme is that the angle of two holes is 60°~90°and distance from center to blowing argon hole is 0.5r~0.7r.
