Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy large flat ingot casting, in particular to an automatic oil control device for aluminum alloy large flat ingot casting. Background Art

[0002] In the casting process of aluminum alloy large flat ingots, the use of lubricating oil is an indispensable part. The main function of lubricating oil is to reduce the friction between metal and mold, improve the quality of castings, and extend the service life of molds. Therefore, the storage, transportation and precise control of lubricating oil are particularly important.

[0003] However, in the existing technology, the storage and delivery system of lubricating oil often has some shortcomings. First, the design of the oil tank and the oil storage tank is relatively simple, lacking real-time monitoring and precise control of the use status of the lubricating oil. This results in the inability to adjust the supply of lubricating oil in real time according to the different specifications and casting requirements of the aluminum alloy large flat ingots during the casting process. Secondly, the delivery pipeline of the lubricating oil is usually not equipped with monitoring equipment such as flow meters, so that the flow of the lubricating oil cannot be effectively monitored, which in turn affects the stability of the casting process and the quality of the castings.

[0004] In addition, in existing casting systems, the level control of lubricating oil often relies on manual operation and empirical judgment. This method is not only inefficient, but also prone to errors, resulting in waste or insufficient lubricating oil. Especially when casting large slabs of aluminum alloys of different specifications, it is difficult to achieve precise adjustment by manual control due to the difference in the demand for lubricating oil.

[0005] In summary, the existing aluminum alloy large slab casting system has obvious deficiencies in lubricating oil storage, transportation and liquid level control. Utility Model Content

[0024] The utility model aims to provide an automatic oil control device for casting large flat ingots of aluminum alloy, which can realize accurate oil control during casting of large flat ingots of different specifications.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 As shown, the utility model provides an automatic oil control device for casting large flat ingots of aluminum alloy, comprising:

[0027] Oil tank 1, used for storing lubricating oil;

[0028] Oil storage tank 2, used for storing excess lubricating oil;

[0029] The crystallizer 3 has a liquid level sensor 4 on its inner wall, and the top wall is connected to the oil tank 1 through an oil inlet 5, and the bottom wall is connected to the oil storage tank 2 through an oil outlet 6; wherein the oil inlet 5 and the oil outlet 6 are both provided with valves;

[0030] The controller is connected to the liquid level sensor 4 and each valve through a data connection line, and is arranged on the outer wall of the crystallizer 3, and is used to control the amount of lubricating oil during casting of the aluminum alloy large flat ingot according to the liquid level corresponding to the set specification.

[0031] As a further technical solution, the oil inlet 5 and the oil tank 1 are connected via a first pipe 7, and a flow meter 8 is also provided on the first pipe 7; the flow meter 8 is connected to the controller. The oil outlet 6 and the oil storage tank 2 are connected via a second pipe 9, and a funnel 10 is also provided on the oil inlet 5 of the oil storage tank 2, and the second pipe 9 and the funnel 10 are detachably connected.

[0032] The number of the liquid level sensors 4 is set to one or more. When the number of the liquid level sensors 4 is set to multiple, they are sequentially arranged on the inner wall of the crystallizer 3 from bottom to top according to the amount of lubricating oil required by different setting specifications. In this embodiment, the model of the liquid level sensor 4 is FS-IR02.

[0033] Based on the above technical solution, the following embodiments are provided.

[0034] In this specific embodiment, the casting process of aluminum alloy large flat ingots using the present device will be described in detail, which achieves optimization of the casting process and improvement of casting quality by precisely controlling the supply amount of lubricating oil.

[0035] First, the oil tank 1 is installed at a suitable position of the casting equipment to store sufficient lubricating oil. The oil tank 1 adopts a sealing design to prevent the lubricating oil from being contaminated or volatilized.

[0036] The oil storage tank 2 is located below the oil tank 1 and is used to collect excess lubricating oil discharged from the crystallizer 3. The oil storage tank 2 also adopts a sealed design and is equipped with a discharge port to facilitate regular cleaning and replacement of the lubricating oil.

[0037] The crystallizer 3 is the core component of the aluminum alloy large flat ingot casting, and a liquid level sensor 4 is arranged on its inner wall. In this embodiment, the FS-IR02 liquid level sensor 4 is selected, which has the characteristics of high precision and high reliability and can detect the lubricating oil level in the crystallizer 3 in real time.

[0038] The top wall of the crystallizer 3 is provided with an oil inlet 5, which is connected to the oil tank 1 through a first pipe 7. A flow meter 8 is installed on the first pipe 7 to monitor the flow of the lubricating oil in real time. The flow meter 8 is connected to the controller through a data connection line, so that the controller can obtain the flow data of the lubricating oil in real time.

[0039] The bottom wall of the crystallizer 3 is provided with an oil outlet 6, which is connected to the oil storage tank 2 through a second pipe 9. The second pipe 9 is detachably connected to the funnel 10 on the oil inlet 5 of the oil storage tank 2, which is convenient for cleaning and maintenance.

[0040] The controller is the core component of the whole system. It is connected to the liquid level sensor 4, flow meter 8 and each valve through data connection lines. The controller is preset with the lubricating oil level and flow data required for casting of large flat ingots of different specifications of aluminum alloy. During the casting process, the controller receives the data of the liquid level sensor 4 and flow meter 8 in real time according to the set specifications, controls the switch state of each valve through calculation and analysis, and thus accurately controls the supply of lubricating oil.

[0041] Specifically, when the aluminum alloy large flat ingot is cast, the controller opens the valve of the oil inlet 5 according to the set specifications, so that the lubricating oil flows from the oil tank 1 into the crystallizer 3 through the first pipeline 7. At the same time, the flow meter 8 monitors and records the flow data of the lubricating oil in real time. When the liquid level sensor 4 detects that the lubricating oil in the crystallizer 3 reaches the preset liquid level, the controller closes the valve of the oil inlet 5 and stops the supply of the lubricating oil.

[0042] During the casting process, if the level sensor 4 detects that the lubricating oil level in the crystallizer 3 drops, the controller will open the valve of the oil inlet 5 again to replenish the lubricating oil to the preset level. Similarly, if the lubricating oil flow exceeds the preset range, the controller will control the flow by adjusting the valve opening to ensure the stability and accuracy of the lubricating oil supply.

[0043] When casting is completed, the controller will open the valve of the oil outlet 6 to allow excess lubricating oil to flow into the oil storage tank 2 through the second pipeline 9. This can avoid the waste of lubricating oil and keep the crystallizer 3 clean and dry.

[0044] Through the aluminum alloy large flat ingot casting system in this specific embodiment, we can achieve accurate control of the lubricating oil supply, thereby improving the stability of the casting process and the quality of the casting. At the same time, the system also has the advantages of simple structure, convenient operation, low maintenance cost, etc., and is suitable for large-scale production of aluminum alloy large flat ingots.

[0045] It can be seen that this embodiment has the following beneficial effects:

[0046] First, the system greatly improves the stability of the casting process and the quality of castings by accurately controlling the supply of lubricating oil. The level sensor monitors the lubricating oil level in the crystallizer in real time to ensure that the amount of lubricating oil is always kept within the set range, thus effectively avoiding casting defects caused by insufficient or excessive lubricating oil.

[0047] Secondly, the use of flow meters enables the flow of lubricating oil to be effectively monitored and managed. The controller adjusts the valve opening in real time according to the flow data, ensuring a stable supply of lubricating oil, further improving the controllability of the casting process and the consistency of the castings.

[0048] In addition, the design of the oil storage tank allows the excess lubricating oil to be recycled, reducing production costs and meeting environmental protection requirements. The detachable second pipe is connected to the funnel, which facilitates cleaning and maintenance and increases the service life of the equipment.

[0049] Finally, the setting of multiple liquid level sensors enables the system to more accurately control the amount of lubricating oil according to different set specifications. This flexible configuration method enables the system to adapt to the casting needs of large slabs of aluminum alloy with different specifications, improving the versatility and efficiency of the equipment.

[0050] In summary, the aluminum alloy large flat ingot casting system optimizes the casting process and improves the quality of castings by accurately controlling the supply of lubricating oil, effectively monitoring the flow, and flexibly configuring liquid level sensors. At the same time, it reduces production costs and increases the service life of equipment, with significant beneficial effects.
