Abstract:
Based on the similar principle, water modeling experiment was carried out for the 150 t ladle furnace at Tianjin Pipe Corporation Ltd. (the geometry ratio is 1:4 between the model and prototype). It was found that the holes' positions weren't rational completely, porous brick was small, and gas flow rate was a little large. The rational argon blowing process is determined by optimizing experiments:the holes are moved to the position of 1/3
R, the top diameter of porous brick is increased to 35 mm from 16 mm, and the gas flux is con-trolled to 0.44m
