During the smelting process of aluminum and aluminum alloys, the impurities brought by the furnace and charge, (especially when there are more materials in the furnace), and the oxides and other impurities generated during the melting process, these impurities are refined after refining The gas is brought to the surface of the molten aluminum under the physical or chemical action of the refining agent to form slag. These slags always contain more or less aluminum. If they are removed from the furnace without treatment, they will inevitably cause the loss of aluminum. A flux with heat generation, good slag performance and quick reaction is selected for in-furnace treatment in order to achieve the effect of slag-aluminum separation.
It is precisely for this purpose that the slag treated by the slag-aluminum separator will become quite dry and loose, and there is little aluminum mixed in the slag, thereby reducing the loss of aluminum and improving the purity of the molten aluminum. In addition, The slag cleaning agent also has a good covering and protection effect and can replace the covering agent.
technical parameter
Model: YH-QZ
Shape: white powder, particle size <20 mesh, moisture content below 0.5%.
Scope of application: other aluminum and aluminum alloys except high magnesium alloys.
Reference dosage: Calculated as 0.1-0.2% of the weight of the aluminum melt, increase or decrease according to the furnace type and the purity of the charge.
main advantage
It has good heat generation, separates the aluminum in the slag, and decomposes the alumina in the slag. Makes the aluminum slag dry and loose. It is easy to remove. It forms a protective layer with good fluidity and compactness, which plays a covering role. It prevents the secondary inhalation and oxidation of the aluminum liquid. Reduce the adhesion of slag to the furnace wall and bottom, avoid damage to the furnace body, extend the service life of the furnace body and reduce the number of furnace cleanings. Can be used as a furnace cleaning agent.
Instructions
Before refining or after refining, evenly sprinkle the slag cleaning agent on the surface of the aluminum melt. At this time, due to the reaction of the slag cleaning agent, a lot of heat is released, which makes the slag rapidly heat up and red, and stir the slag in time. When the slag becomes broken After powdering, remove the slag powder.
If the slag cleaning agent is used for covering, it should be sprinkled into the furnace in three times, added when the charge starts to melt, *the second time is added after all melting, and the third time is mainly for the separation of slag and aluminum. It should be sprinkled on the melting after refining. Slag surface. It can be adjusted according to the reference dosage.
