Problems solved by technology

In the casting process, the molten metal used for casting is often mixed with more or less oxidized slag. These oxidized slags are often fine scum that has not been removed in the previous refining process. If the small particle scum produced by oxidation is not removed as much as possible during the casting process, it will seriously affect the quality of the product and cause a large number of cast metal ingot products to be unqualified
[0003] In the conventional casting process, the metal melt is directly injected into the mold through the quantitative feeding device. Due to the fast flow rate of the metal melt, part of the oxidized slag mixed in it will accumulate on the side wall of the mold and be wrapped by the condensed liquid metal, resulting in In addition, although the oxide slag on the surface of the casting mold can be removed by scraping the open surface, if the cast metal melt itself contains a large amount of oxide slag, the edge of the ingot surface will It is also prone to oxide inclusions
[0004] Therefore, in order to avoid the fine oxidized slag in the metal melt during the ingot opening process, the side walls and edges of the metal ingot are difficult to remove, resulting in the occurrence of unqualified metal ingot products. A device for effectively removing oxidized slag is a technical problem urgently needed by those skilled in the art

Embodiment 1

[0047] The casting process of embodiment 1 refined tin ingot

[0048] Put the quantitative pump 8 into the refined tin liquid heat preservation pot, and then connect the liquid injection end bracket 1 with the probe to the linear ingot casting machine. After the casting mold 4 is preheated, start the linear casting machine and start the quantitative pump.

[0049]When the device is used for casting for the first time, because part of the tin liquid pumped by the quantitative pump is blocked by the buffer baffle 7 and remains in the buffer transition box 6, the first casting mold cannot be filled, and the first ingot is used as the Handling of defective products. Afterwards, with the movement of the linear ingot casting mold, the probe on the liquid injection end bracket 1 detects the next empty casting mold and sends a feedback signal to the quantitative pump 8 for a quantitative delivery. From the second quantitative delivery, since the buffer transition box 6 has stored the...

Embodiment 2

[0052] Example 2: Casting process of refined lead ingot

[0053] Put the quantitative pump 8 into the lead liquid heat preservation pot, and then connect the liquid injection end bracket 1 with the probe to the linear ingot casting machine. After the mold 4 is preheated, start the linear casting machine and start the quantitative pump.

[0054] During the first casting, because part of the lead liquid pumped by the quantitative pump is blocked by the buffer baffle 7 and remains in the buffer transition box 6, the first casting mold cannot be filled, and the first ingot is regarded as unqualified. product processing. Afterwards, with the movement of the linear ingot casting mold, the probe on the liquid injection end bracket 1 detects the next empty casting mold and sends a feedback signal to the quantitative pump 8 for a quantitative delivery. From the second quantitative delivery, since the buffer transition tank 6 has stored lead liquid, the lead liquid entering the transit...

Abstract

The invention discloses an automatic casting device with buffering and residue filtering functions. The automatic casting device comprises a liquid injection end support with a probe, a duck head infusion tube, a wind wheel type casting liquid outlet device, a casting mold and a metering pump. The duck head infusion tube extends into the liquid injection end bracket with the probe, and the other end of the duck head infusion tube is fixedly connected with the bottom end of the metering pump; the wind wheel type casting liquid outlet device is fixed inside the liquid injection end bracket with the probe, and the duck head infusion tube extends into the wind wheel type casting liquid outlet device; the casting mold is fixed to the bottom end of the liquid injection end support of the probe, and the bottom end of the wind wheel type casting liquid outlet device is connected with the top end of the casting mold. After buffering and residue filtering are conducted through the device, the product percent of pass of an automatic casting assembly line is increased, the product returning rate is reduced, and then the production work efficiency is improved. The device is widely suitable for the casting process of low-melting-point metal product ingots such as tin, lead and zinc.

Description

technical field [0001] The invention relates to the technical field of metal ingots, in particular to an automatic casting device with the function of buffering and filtering residues. Background technique [0002] At present, the metal melt that has completed the refining process must be cast into a metal ingot of a specified shape and weight in a casting mold before it can be sold as a metal product. During the casting process, the metal melt used for casting is often mixed with more or less oxide slag. These oxide slag are often the small scum that has not been removed in the previous refining process, and some metal melts are removed during the transfer process. If the small particle scum produced by oxidation is not removed as much as possible during the casting process, it will seriously affect the quality of the product and cause a large number of cast metal ingot products to be unqualified. [0003] In the conventional casting process, the metal melt is directly inj...
