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.

摘要： Provided are an agitation device, a melting apparatus, and a melting method which achieve good melting efficiency without contaminating molten metal. The agitation device (150) is provided with a traveling magnetic field generating unit (160) which is disposed outside a charging tank (20) for storing molten metal (3) and generates, inside the charging tank (20), a magnetic field that travels downward along the rear sidewall (22) of the charging tank (20), whereby a flow of the molten metal (3) that rotates longitudinally about an axis approximately parallel to the surface of the molten metal (3) is produced in the molten metal (3). By charging aluminum cutting chips (2) into the molten metal (3) in which the flow is produced, the aluminum cutting chips (2) move with the flow of the molten metal (3), get into the molten metal (3) roughly in the position where a downward flow of the molten metal (3) is produced, and are immersed in the molten metal (3), and thus the melting of the aluminum cutting chips (2) is accelerated.

摘要： A device and method for removing impurities in aluminum melt. The device comprises an upper furnace body, a lower furnace body, an intermediate partition plate, a crucible, heating elements and a charging opening. The intermediate partition plate is mounted between the upper furnace body and the lower furnace body. The upper furnace body, a mixing chamber and the heating element are above the intermediate partition plate. The crucible is amounted in the lower furnace body. The heating element is provided around the lower furnace body. The lower furnace body is provided with the charging opening and a pipeline. The upper furnace body is provided with an inlet valve and an exhaust valve. The mixing chamber and the crucible are connected by a jet pipe passing through the intermediate partition plate. A ceramic seal pad is used for sealing between the mixing chamber and the jet pipe. During use, the aluminum melt and a liquid flux are placed in the crucible, the liquid flux covers the aluminum melt, the pressure of the lower furnace body is increased, the aluminum melt first stably enters the mixing chamber along the jet pipe, then the liquid flux enters the mixing chamber in a manner of confined jet flow and is uniformly mixed with the aluminum melt, last the pressure of the lower furnace body is unloaded, so that the mixed liquid falls back into the crucible, and this operation may be repeated for multiple times. For the device and the method, the impurity removal is quick, the efficiency is high and the process is closed, so there is no environmental pollution, and the aluminum melt after the impurity removal may be directly cast.
