摘要：
A process of eliminating impurities dissolved in a contaminated liquid metal, continuously, by applying an electromagnetic field generated by linear induction pumps on the contaminated metal crosswise to a second duct through which the metal flows. The current density circulates lengthwise to the duct, and therefore, according to Lorentz force law, an electromagnetic force that is perpendicular to both is produced. When the impurities have a difference in electrical conductivity of at least one order of magnitude in decimal power, the resulting force that acts upon the particles causes a relative movement of these with respect to said metal, such that they can be moved and separated from said molten metal in a previous metallurgical step a particle is formed having an adequate electrical conductivity. The installation includes the aforementioned components in order to carry out the process.
