MATHEMATICAL MODELING OF THE INFLUENCE OF VIBRATION ON THE REFINING OF MOLTEN METALS
Abstract
The kineto-static method based on D'Alembert' principle is used to develop a mathematical model of the vibrational refining of molten metals. The model calculations show the possibility of increasing the efficiency of the removal process from melt gases and impurities.
The impact of physico-chemical properties of metal, the vibration parameters and mold on the refining process is discussed. The calculations are performed by the model for the molten steel, which show that in the case of inclined vibration (a=45°) and bubble size R from 0.1 to 1 mm, surface forces dominate over the static pressure and the floating of particles is accelerated.
