Description

Technical Field

[0001] This utility model relates to the field of metallurgical testing technology, specifically to a metallurgical molten pool height detection device that provides image recognition. Background Technology

[0002] In metallurgical production, the measurement of the molten pool height is a crucial process parameter. Currently, the most common method relies on manual measurement using a probe inserted into the molten pool. While simple, this method has the following drawbacks: 1. The operation is physically demanding for the operators, as the probe needs to be operated in a high-temperature environment, posing serious safety hazards; 2. The probe is prone to thermal deformation at high temperatures, resulting in poor measurement accuracy; 3. Measurements often rely on experience and judgment, resulting in large errors; 4. The long sampling period and delayed response are not conducive to real-time control of the process.

[0003] The temperature of molten metal pools can reach 1300℃~1450℃. Under these conditions, traditional manual detection methods are difficult to guarantee safety and accuracy. Therefore, there is a need for a device that can achieve real-time measurement, reduce labor intensity, and improve safety in detecting the height of molten metal in the pool. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a metallurgical molten pool height detection device with image recognition capability. This device uses a high-temperature camera to observe the internal conditions of the molten pool in real time, thereby achieving real-time detection of the molten pool height. This solves the problems of high labor intensity, poor accuracy, and safety hazards associated with manual detection in existing technologies.

[0005] A metallurgical molten pool height detection device for image recognition includes a high-temperature camera, a cooling device, and a pre-set scale inside the furnace. A high-temperature camera mounting component is located on the side of the furnace, and a high-temperature camera is installed within the mounting component. The high-temperature camera is connected to a control terminal. The device is characterized by: an observation port for the high-temperature camera to capture images of the furnace interior between the furnace and the high-temperature camera mounting component; a ball valve on the observation port; a protective mirror on the high-temperature camera mounting component; a scale inside the furnace; and an air-cooling system and a water-cooling system for cooling.

[0006] Furthermore, the water cooling system includes a cooling water channel, a cooling water outlet, and a cooling water inlet; the cooling water channel is located inside the high-temperature camera mounting component and surrounds the surface of the high-temperature camera; the cooling water inlet is located at the lower end of the high-temperature camera mounting component and enters the high-temperature camera mounting component and connects to the cooling water channel; the cooling water outlet is located at the upper end of the high-temperature camera mounting component and enters the high-temperature camera mounting component and connects to the cooling water channel.

[0007] Furthermore, the air-cooling system includes a compressed air inlet and a compressed air outlet; the compressed air inlet is located at the upper end of the high-temperature camera mounting component; the compressed air outlet is located at the connection surface between the high-temperature camera mounting component and the furnace.

[0008] Furthermore, the protective mirror surface is a flame-retardant mirror surface.

[0009] Furthermore, the high-temperature camera is also equipped with a protective cover, and the protective cover is also equipped with a temperature sensor.

[0010] Furthermore, both the temperature sensor and the ball valve are electrically connected to the control terminal.

[0011] The smelting furnace is a high-temperature, enclosed environment. During production, the combustion inside the furnace cannot be observed. Measuring the liquid level with a probe requires manual inspection, which is labor-intensive and poses significant safety hazards. By setting up a high-temperature camera, the internal combustion and liquid level can be observed directly and transmitted to the terminal in real time, providing a basis for actual production and adjustments.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Real-time measurement of molten liquid height in the molten pool is achieved by replacing the probe with a high-temperature camera, reducing the intensity of manual labor. It allows for direct and real-time observation of the combustion situation inside the furnace, providing a certain reference for production adjustments in the smelting furnace; 3. It avoids direct contact between personnel and high-temperature environments, eliminating potential safety hazards; 4. By combining the flame-retardant mirror with the scale inside the furnace, high-precision image recognition and measurement can be obtained; 5. The high-temperature camera is kept stable for a long time through air cooling and water cooling systems; 6. By linking the temperature sensor with the ball valve, automatic protection and alarm functions are achieved, improving system reliability. Attached Figure Description

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0015] like Figure 1-2 As shown, a metallurgical molten pool height detection device for image recognition includes a furnace 1 and a high-temperature camera mounting component 2 disposed on the side wall of the furnace. A high-temperature camera 3 is fixedly installed inside the high-temperature camera mounting component 2 and electrically connected to a control terminal. An observation port 4 is provided between the furnace 1 and the high-temperature camera mounting component 2, and a ball valve 5 is fitted on the observation port 4 to open during detection and close when not detecting, preventing the leakage of high-temperature gas from the furnace.

[0016] A protective mirror 6 is installed on the high-temperature camera mounting component 2. The protective mirror 6 is preferably a flame-retardant mirror to prevent damage to the lens from sparks and molten slag. A scale 7 is provided inside the furnace 1. The scale 7 is matched with the scale in the camera's field of view to achieve calibration and real-time measurement of the molten liquid height.

[0017] The high-temperature camera mounting component 2 is equipped with a water cooling system, including a cooling water channel 21 surrounding the high-temperature camera 3. The cooling water channel 21 is connected to an external water channel through a cooling water inlet 22 at the lower end and a cooling water outlet 23 at the upper end, thereby achieving circulating cooling.

[0018] The high-temperature camera mounting component 2 is also equipped with a cooling system, including a compressed air inlet 31 at the top and a compressed air outlet 32 ​​at the connection with the furnace. Cold air enters from the compressed air inlet 31 and is discharged from the compressed air outlet 32, further reducing the operating temperature of the high-temperature camera.

[0019] In addition, a protective cover 8 is installed on the outside of the high-temperature camera 3, and a temperature sensor 9 is installed on the protective cover 8. When the temperature exceeds the preset value (such as 80°C), the temperature sensor 9 sends a command through the control terminal to automatically close the ball valve 5 and alarm to prompt maintenance personnel to carry out maintenance.

[0020] Furthermore, the working principle, calibration method, and measurement method are as follows: Calibration method: ① Adjust and fix the installation angle of the high-temperature camera 3. ② Find a suitable sampling object; in this embodiment, the scale on the furnace wall opposite the sampling camera is the sampling object. ③ Mark the height of the sampling object. ④ Mark the scale of the flame-retardant mirror of the high-temperature camera 3. ⑤ Adjust the camera focal length so that the ratio of the height of the sampling object to the scale of the flame-retardant mirror of the high-temperature camera 3 is close to a ratio that is easy to calculate manually (10:1 or 20:1, etc.).

[0021] Measurement method: ① Check all water lines, gas lines, instruments, and valves for proper functioning. ② Activate automatic measurement mode. ③ Automatically open observation port 4 and ball valve 5 to begin measurement. ④ When the high-temperature camera protective cover 8 reaches 80℃, automatically close observation port 4 and ball valve 5, and trigger an alarm to prompt maintenance personnel for inspection and maintenance.
