Description

Technical Field

[0001] This utility model relates to the field of tool technology for the metallurgical and casting industries, and in particular to an aluminum molten soup ladle with a temperature measuring device. Background Technology

[0002] Aluminum molten ladle is an important tool widely used in the metallurgical and casting industries. It is mainly used to scoop and transfer molten aluminum. In the semi-solid forming process, precise control of the aluminum molten temperature is a key link to ensure the quality of castings. Too high a temperature may cause defects such as porosity and shrinkage porosity in the castings, while too low a temperature will affect the fluidity of the aluminum molten, thus causing incomplete pouring or cold shut. Therefore, the temperature of the aluminum molten before slurry preparation becomes a core parameter that needs to be strictly controlled in the entire process.

[0003] Currently, the temperature of molten aluminum before slurry preparation is affected by various factors, including the initial temperature of the molten aluminum in the holding furnace, the temperature of the molten aluminum ladle and its heat dissipation characteristics, ambient temperature and humidity, and heat loss during transportation. Currently, the temperature of the molten aluminum is generally monitored indirectly through thermocouples inside the holding furnace, and this is used as the main basis for temperature control. However, this method has significant shortcomings: the temperature fluctuation range of a machine-side melting holding furnace is typically ±10℃, and that of a machine-side holding furnace is ±5℃. Even the most advanced quantitative furnaces still exhibit temperature fluctuations of ±3℃, indicating significant temperature volatility. Furthermore, the temperature fluctuation is further affected when scooping the molten aluminum from the holding furnace... During the process of transporting the molten aluminum to the pulping location, the temperature of the molten aluminum will drop further by 5 to 15°C due to factors such as environmental heat dissipation. However, the scoops of the mainstream automatic molten aluminum dispensing machines on the market generally lack the function of directly measuring the temperature of the molten aluminum. Although the equipment is equipped with indirect temperature measurement methods, these methods cannot accurately reflect the actual temperature changes of the molten aluminum during the scooping, transportation, and pulping preparation stages. The combination of these factors makes it difficult to achieve high-precision detection and control of the actual temperature of the molten aluminum before pulping. Therefore, relying solely on the temperature readings of the thermocouples in the holding furnace can no longer meet the high-precision temperature control requirements of modern semi-solid forming processes.

[0004] Therefore, developing an aluminum molten ladle with a temperature measuring device that can measure the temperature of molten aluminum in real time is of great significance for improving the control accuracy of molten aluminum temperature in semi-solid forming processes, thereby improving product quality and production efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of existing aluminum liquid ladles that cannot measure the temperature of aluminum liquid, making it difficult to accurately control the temperature of aluminum liquid before slurry preparation and affecting the quality of aluminum liquid castings, this utility model provides an aluminum liquid ladle with a temperature measuring device that can measure the temperature of aluminum liquid in real time.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an aluminum liquid ladle with a temperature measuring device, comprising an aluminum liquid ladle body, an inlet at the front edge of the aluminum liquid ladle body, an outlet at the rear edge of the aluminum liquid ladle body, a wire groove inside the aluminum liquid ladle body extending from the bottom of the body to the side, a thermocouple installed inside the wire groove with its probe directly contacting the molten aluminum, and the thermocouple connected to an external temperature measuring instrument via a temperature compensation wire.

[0007] Furthermore, a baffle is provided on the top of the aluminum liquid ladle body, and a locking rod is provided on both sides of the baffle. A locking groove matching the locking rod is provided on both sides of the aluminum liquid ladle body, and a buckle is provided at the lower end of the locking rod.

[0008] Furthermore, the temperature compensation line is fitted with two silicone rubber protective sleeves, which can be combined into a whole. One of the silicone rubber protective sleeves has a first arc-shaped locking block at both ends, and the other silicone rubber protective sleeve has a second arc-shaped locking block at both ends. The first arc-shaped locking block and the second arc-shaped locking block can be locked together.

[0009] Furthermore, multiple retaining rings are fitted together on the outside of the two silicone rubber protective sleeves.

[0010] Furthermore, a slag-blocking plate is fixedly connected to the liquid inlet of the aluminum liquid ladle body.

[0011] Furthermore, a protective shell is fixed to the side of the baffle closest to the thermocouple.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By integrating a thermocouple temperature measuring device into the aluminum liquid ladle, the actual temperature of the aluminum liquid can be measured directly and in real time, and the signal can be transmitted to an external temperature measuring instrument through a temperature compensation line, so that the operator can grasp the temperature change of the aluminum liquid in real time, which is convenient for timely adjustment of process parameters. This helps to optimize the semi-solid forming process and other high-temperature metal processing processes, reduce quality defects caused by temperature fluctuations, and improve casting quality and production efficiency.

[0013] 2. By installing a baffle on the top of the molten aluminum ladle, the area above the outlet can be effectively covered, preventing molten aluminum from splashing during the pouring process. This significantly reduces the risk of burns to operators caused by hot molten aluminum splashing and improves the safety of equipment use.

[0014] 3. The silicone rubber protective sleeve provides all-around protection for the surface of the temperature compensation line, effectively preventing damage caused by external mechanical damage, chemical corrosion, and high-temperature environments, thus extending its service life.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1 and Figure 2A ladle with a temperature measuring device for molten aluminum includes a ladle body 1. The ladle body 1 has a liquid inlet 101 at its front edge for scooping molten aluminum. A baffle plate 12 is fixedly connected to the liquid inlet 101. The baffle plate 12 effectively prevents slag from flowing into the molten aluminum when scooping, thus improving the quality of the aluminum casting. The ladle body 1 has an outlet 102 at its rear edge for pouring out molten aluminum. The ladle body 1 has a groove inside, extending from the bottom of the ladle body 1. Extending to the side, a thermocouple 2 is installed inside the wire groove, with its probe directly contacting the molten aluminum to measure the temperature of the molten aluminum in real time. The thermocouple 2 is connected to an external temperature measuring instrument through a temperature compensation line 3 to transmit the thermoelectric potential signal generated by the thermocouple 2 to the measuring instrument, thereby realizing the real-time measurement of the temperature of the molten aluminum. A protective shell 13 is fixed to the side of the baffle 4 near the thermocouple 2. The protective shell 13 is used to cover the connection between the thermocouple 2 and the temperature compensation line 3 to prevent this part from being damaged by external factors (such as mechanical collision, high temperature, corrosion, etc.).

[0023] When using the aluminum molten ladle, the operator scoops the molten aluminum into the ladle through the front inlet 101. After the aluminum molten enters the ladle, the thermocouple 2 probe immediately comes into contact with the aluminum molten and begins to measure the aluminum molten temperature in real time. The thermocouple 2 probe converts the detected aluminum molten temperature into a thermoelectric potential signal and transmits it to an external temperature measuring instrument through the temperature compensation line 3. The temperature measuring instrument processes and displays the received signal, and the operator can read the aluminum molten temperature in real time to ensure that it meets the process requirements. After the temperature measurement is completed, the operator moves the aluminum molten ladle to a designated position (such as a pulping device) and pours the aluminum molten out through the rear outlet 102.

[0024] Example 2: Based on Example 1, please refer to... Figure 3 The aluminum liquid ladle body 1 is provided with a baffle 4 on the top to cover the area above the liquid outlet 102. The baffle 4 is provided with a locking rod 5 on both the left and right sides. The aluminum liquid ladle body 1 is provided with a locking groove 6 on both the left and right sides to match the locking rod 5. The locking rod 5 is provided with a buckle 7 at the lower end to lock the locking rod 5.

[0025] Before using the molten aluminum ladle, place the baffle 4 on top of the ladle body 1, align the latches 5 on both sides of the baffle 4 with the slots 6 on both sides of the ladle body 1, and insert the lower end of the latches 5 into the slots 6. Then, insert the buckle 7 into the lower end of the latches 5 to prevent them from loosening or falling off. After installation, the baffle 4 can effectively cover the area above the outlet 102, preventing molten aluminum from splashing during the pouring process and avoiding waste or safety hazards caused by splashing.

[0026] Please see Figure 4 and Figure 5The temperature compensation line 3 is covered with two silicone rubber protective sleeves 9. The two silicone rubber protective sleeves 9 can be combined into a whole to provide all-round protection for the temperature compensation line 3. Each silicone rubber protective sleeve 9 has a first arc-shaped locking block 8 at both ends, and the other silicone rubber protective sleeve 9 has a second arc-shaped locking block 10 at both ends. The first arc-shaped locking block 8 and the second arc-shaped locking block 10 can be locked together to fix the two silicone rubber protective sleeves 9 together. The two silicone rubber protective sleeves 9 are covered with eight fixing rings 11. The fixing rings 11 are used to further fix the two silicone rubber protective sleeves 9 and prevent them from loosening or misaligning during use.

[0027] By placing two silicone rubber protective sleeves 9 on the surface of the temperature compensation line 3, ensuring that they cover the entire outer surface of the temperature compensation line 3, and aligning the first arc-shaped locking block 8 and the second arc-shaped locking block 10 at each end, the first arc-shaped locking block 8 and the second arc-shaped locking block 10 are fixed by a snap-fit ​​operation, thereby making the two silicone rubber protective sleeves 9 tightly bonded. After installation, the silicone rubber protective sleeves 9 can effectively protect the surface of the temperature compensation line 3 and prevent it from being damaged by external mechanical damage, chemical corrosion or high temperature environment.
