Description
  • One important process of steelmaking technology is argon-vacuum degassing. Bubbles are responsible for three effects of the process: -mass transfer - removal of diluted gases,-flotation of immiscible particles to the level,-air-lift effect - homogenization of the steel.Important way of gas removal is evacuation of the system. Change from the %22ferrostatic%22 pressure means that the bubble volume increases 10000 times during its floating to the level. According to it, breakup of increasing bubbles is in the focus of interest. Direct observation of bubbles in liquid steel is quite complicated; therefore modeling is an suitable approach. The process was investigated experimentally with large bubbles levitating in downstream water flow. Statistic results were introduced to the theoretical model of argon-vacuum steel degassing ladle. Local distribution of the size, velocity and number of bubbles was obtained. These results can be applied to predict liquid circulation velocity and mass transfer coef
