The utility model relates to the technical field of metal ingots, in particular to an automatic casting device with a filter residue buffering function.
Background
At present, the metal melt after the refining process is cast into metal ingots with specified shapes and weights in a casting mould to become metal products for sale. In the casting process, the metal melt used for casting is often mixed with more or less oxidation slag, the oxidation slag is often fine scum which is not removed in the previous refining process, and small-particle scum generated by oxidation of the metal melt in the transfer process is also present, and if the oxidation slag is not removed as much as possible in the casting process, the quality of the product can be seriously influenced, and the unqualified large-batch cast metal ingot products are caused.
In the conventional casting process, the metal melt is directly injected into the casting mold through the quantitative feeding device, because the flow velocity of the metal melt is high, part of oxide slag mixed in the metal melt is flushed on the side wall of the casting mold and is wrapped by condensed liquid metal, so that oxide slag mixing occurs on the side wall of a produced metal ingot, and in addition, although the oxide slag on the surface of the casting mold can be removed in a mode of scraping slag through an open surface, if the amount of the oxide slag contained in the cast metal melt is large, the situation of oxide slag mixing easily occurs on the edge of the surface of an ingot.
Therefore, in order to avoid the situation that the side wall and the edge of the metal ingot are difficult to remove completely in the process of opening the cast ingot by fine oxidation slag in the metal melt, so that the metal ingot is unqualified, the device for effectively removing the inclusion oxidation slag in the casting process of the metal melt is a technical problem which needs to be solved by technical personnel in the field.
