Description

Technical Field

[0001] The utility model relates to the relevant technical fields such as die casting production, and in particular to an automatic anti-oxidation slag device for an aluminum liquid insulation furnace. Background Art

[0002] With the increase of new energy vehicles and the demand for lightweight vehicles, there are more and more types of die-castings, and at the same time, there are high requirements for the mechanical properties of die-castings. However, the oxide slag and oxide film in the insulation furnace have a great influence on the mechanical properties of die-castings. When the aluminum liquid is heated and insulated in the insulation furnace, it is inevitable to produce oxides. Since the oxide floats on the aluminum liquid, when the aluminum liquid level drops to the aluminum liquid connecting hole of the retaining wall, the oxide in the insulation chamber will directly reach the discharge port. At this time, the aluminum liquid taken will have oxides that affect the mechanical properties of the casting. The usual practice is that the operator needs to add materials in time when the liquid level is low. In this way, it is often found that the liquid level is too low and the oxide has reached the discharge port through the aluminum liquid connecting hole. At this time, the machine can only be stopped to clean the aluminum liquid oxide and scrap the previously produced castings, which seriously affects production efficiency and also has great quality risks.
