MATHEMATICAL SIMULATION OF CONVECTIVE DIFFUSION IN AN ENERGY-SAVING MODE OF DEGASSING OF A METAL MELT BY A COMPLEX ACTION

On the basis of the developed model, the authors have made a numerical analysis of the convective diffusion of hydrogen in a liquid bath (degree of its degassing) as a function of the technological parameters of the process. It has been established that the effi ciency of the diffusion processes decreases with increase in the diameter of the purger pores and in the pressure in a vacuum chamber, and increases with liquid-bath depth and blowing rate, but to a certain level, after which the process′s effi ciency ceases to grow. It has been shown that the reduction in the rate of blowing to an optimum level saves expensive argon
