After refining of aluminum and aluminum alloys, there is a thick layer of scum on the surface of the aluminum liquid. These slags contain more metal aluminum. The function of porous ceramic filter is to increase the surface tension of the slag and the melt.
In the case of agitation, the aluminum liquid and the slag are effectively separated, and the slag is made into a dry powdery slag, which effectively reduces the aluminum content in the slag and reduces the amount of aluminum liquid which is carried out when the slag is slag.
porous ceramic filter produces less smoke when used.
In use, the amount of porous ceramic filter is weighed based on the amount of molten aluminum. Spread the required Drossing Flux evenly on the slag before skimming. After sprinkling, gently blow or agitate the Drossing Flux and the slag to mix well. The ignition temperature is increased for 5-10 minutes (the heating time is determined by the temperature of the aluminum liquid, and if the temperature is low, the heating time can be longer).
During the smelting process, the impurities brought by the furnace and the charge, and the slag formed by the physical or chemical action of the oxidation generated during the melting process, which is brought to the surface of the molten metal, contain more or less alloys. Material,
If it is not treated and cleared out of the furnace, it will inevitably cause loss of material. Therefore, it is necessary to select a kind of solvent with good heat generation and slag performance and quick reflection to carry out furnace treatment, in order to achieve the effect of separation of slag liquid.
