Water model about effect of bottom blowing on slag-steel interface

By using water model to simulate the effect of bottom blowing on turbulence and mass transfer at the slagsteel interface during LD process,the current study aimed to investigate the effects of the gas flow rate and the number of bottom nozzles on the mass transfer and interface turbulence between slag and steel. The results showed that the mass transfer rate between slag and steel changed regularly under different conditions of bottom stirring. The study obtained the maximum mass transfer rate with the combination of the number of bottom nozzles and the gas flow rate. It also showed that the mass transfer rate can reach the maximum if the bottom blowing intensity of individual nozzle was0.020-0.025 m-3/(t·min).
