Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum ingot casting, and particularly relates to an aluminum ingot mold baking device for a continuous casting line. Background Art

[0002] Aluminum ingots are solid blocks of aluminum produced by injecting high-temperature molten aluminum into an ingot mold and then cooling and shaping it. Traditionally, aluminum ingot casting is done manually, which is dangerous and inefficient. Modern aluminum ingot casting generally uses a continuous casting line (also known as an ingot casting machine) to drive the ingot mold in a continuous cycle. A rotating distribution hub automatically pours the molten aluminum into the mold. A cooling water system then sprays or soaks the ingot to accelerate its cooling and shaping, completing the continuous casting process and significantly improving ingot casting efficiency. After the ingot mold is released from the ingot casting machine, some water droplets may remain in the mold. If not dried promptly, the next pour of molten aluminum will cause splashing. This not only results in wasteful molten aluminum but also poses a safety hazard of burns. Therefore, it is necessary to bake the mold after demolding (commonly known as baking the bag) to dry out any remaining water droplets.

[0003] Traditionally, personnel have been assigned to use handheld flamethrowers to bake the aluminum ingot molds, requiring dedicated personnel and increasing labor costs. Existing technologies also incorporate a baking device on the ingot casting machine, but the existing baking device is very simple: a flame burner mounted on the end of a gas pipe with a manual valve. Each baking cycle requires manual opening of the gas valve and ignition, and the power of the flame must be adjusted manually. To ensure sufficient power, not only does it require increased gas flow and usage, but it also requires the use of a fan to provide additional air. Furthermore, if the gas pressure is unstable or low, there is a risk of flashback within the gas pipe. Therefore, further improvements to the existing baking device are necessary.

[0008] Furthermore, the automatic control valve is an electromagnetic ball valve, and the electromagnetic ball valve and the pulse igniter are electrically interlocked with the ingot casting machine and its cooling water system through a control box.

[0009] Furthermore, a bypass pipeline is provided in parallel on the gas inlet pipe between the gas pressure stabilizing valve and the manual switch valve, and a manual control valve is provided on the bypass pipeline.

[0010] Furthermore, the manual switch valve and the manual control valve are both manual ball valves, and the two manual ball valves can be used together as maintenance hand valves during pipeline maintenance.

DETAILED DESCRIPTION

[0017] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0018] Example

[0019] like Figure 1 The figure shows a continuous casting line aluminum ingot mold baking device, comprising an ingot casting machine frame 11, two endless chains 12 that move in an annular manner and are laid on both sides of the frame, a plurality of aluminum ingot molds 13 that are movably bridged between the two endless chains, a cooling water system (not shown) fixedly disposed below the continuously circulating aluminum ingot molds, and a baking assembly fixedly mounted directly in front of the frame head. The ingot casting machine, its frame, endless chains, aluminum ingot molds, cooling water system, etc. are all conventional, and the specific configuration is not detailed here.

[0020] The baking bun assembly includes a gas inlet pipe 14, one end of which is connected to the aluminum ingot mold and fixedly connected to a gas distribution pipe 15 parallel to the length direction of the aluminum ingot mold. Four flame burners 1 for spraying fire toward the aluminum ingot mold are evenly arranged on the wall of the gas distribution pipe close to the aluminum ingot mold, and each of the flame burners is equipped with an ignition needle 8. 。

[0021] The flame burner is a Venturi burner, also known as a mixed-flow Venturi nozzle. It uses high-speed gas jets to create negative pressure while simultaneously drawing in air and evenly mixing the gas and air. This results in a more powerful flame, eliminating the need for a blower as in prior art. The flame burner utilizes the same Venturi burner for gas-fired radiant heating described in patent publication number CN204240357U, a prior art design, and its specific configuration will not be detailed here.

[0022] According to the direction of gas delivery, a gas pressure stabilizing valve 6, an automatic control valve 3 and a manual switch valve 2 are installed on the gas inlet pipe from front to back; a control box 9 is provided on the side of the frame, and a pulse igniter 10 connected to each of the ignition needles is provided in the control box.

[0023] A low-pressure switch 5 and a high-pressure switch 4 are also provided on the gas inlet pipe between the gas pressure-stabilizing valve and the automatic control valve. The automatic control valve and the high- and low-pressure switches are electrically connected to the control box to realize an alarm and automatic shutdown when the gas inlet pipe pressure is too high or too low, and cooperate with the gas pressure-stabilizing valve to achieve pressure stability in the gas inlet pipe and ensure safe use of gas.

[0024] The automatic control valve is an electromagnetic ball valve, and the electromagnetic ball valve and the pulse igniter are electrically interlocked with the ingot casting machine and its cooling water system through the control box. Under normal working conditions, after the ingot casting machine and its cooling water system start working, the electromagnetic ball valve on the gas inlet pipeline will automatically open to supply gas to each flame burner. At the same time, the pulse igniter starts working, so that each ignition needle ignites the Venturi burner and aims at the aluminum ingot mold for flame baking.

[0025] A bypass line 16 is also provided in parallel on the gas inlet pipe between the gas pressure regulating valve and the manual on / off valve, and a manual control valve 7 is provided on the bypass line. Both the manual on / off valve and the manual control valve are manual ball valves, which can be used together as maintenance valves in the event of a pipeline failure in the gas inlet pipe.

[0026] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to ordinary technicians in this technical field. Any technical deformation made within the spirit and principles of the present invention falls within the scope of protection of the present invention.
