Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, specifically to a high-temperature vision camera. Background Technology

[0002] In the metallurgical refining process, it is necessary to film the oxidation-reduction process of the aforementioned molten steel, molten copper, and molten lead under high-temperature heating conditions in the LF refining furnace, copper anode furnace, and lead smelting furnace. Conventionally, the feeding port is opened intermittently for manual observation, and then the oxidation-reduction process is controlled in combination with production experience and process requirements.

[0003] To improve the consistency of production rhythm and refining process, it is necessary to scientifically and objectively describe the redox atmosphere in the refining furnace. This is often achieved by installing a high-temperature vision camera at a suitable position above the refining furnace to capture the reaction process of molten steel, molten copper, and molten lead in the furnace in real time, as well as the magnitude of stirring, the status of carbon source nozzles or submerged arc heating, the magnitude of bottom blowing stirring, and the morphology of refining slag.

[0004] Because the entire reaction process involves a large amount of high-temperature fumes, the flue gas and solid particles from the reaction continuously erode the protective lens of the vision camera. As a result, newly replaced protective lenses lose their basic light transmission after only 1-2 furnace cycles due to slag adhesion and discoloration from baking. While some in the industry have used expensive materials like sapphire for protective lenses to reduce slag adhesion and baking discoloration, these still cannot be used long-term in the aforementioned environment and quickly lose their basic function of real-time imaging. Furthermore, due to limitations in the pre-melting or flexible customization requirements during production, furnace volume deviations in the refining stage can cause the high-temperature vision camera to lose focus. In high-intensity stirring processes such as desulfurization, the camera is required to have dynamic focusing capabilities, which is a current pain point in the industry. Due to cost control and the development of real-time temperature measurement technology, the production process often uses point temperature detection at stages such as heating, alloying, and deoxidation. In fact, the reaction inside the furnace is continuous, requiring high-precision measurement of the regional temperature of the flow field inside the furnace and the liquid temperature within the calibrated target range to provide operators and process engineers with reference values ​​for the molten pool temperature during the production process. The measurement target is within the range of 1600 degrees Celsius. Conventional infrared measurement methods often have large measurement errors and are not very practical in the field.

[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] Please see Figures 1-5 The present invention provides the following technical solution:

[0023] A high-temperature vision camera includes a vision camera 2, which is mounted on the bottom of a cylindrical tube 1. The cylindrical tube 1 contains a new film compartment 4, a geared motor 3, and a storage compartment 5. The geared motor 3 is located between the storage compartment 5 and the new film compartment 4. The vision camera 2 is located on the side of the storage compartment 5 and the new film compartment 4. The new film compartment 4 and the storage compartment 5 are equipped with a counting device, which can determine the operation time for changing the film compartment according to the production rhythm and measure the number of high-temperature resistant lenses placed in the new film compartment 4 and the storage compartment 5. The top of the new film compartment 4 and the storage compartment 5 are both fitted with a cover 7. The high-temperature lenses are made of high-temperature resistant glass and can be replaced automatically or by command. The high-temperature vision camera 2 is in the shape of a cylindrical tube 1 that integrates water cooling and air cooling. All electrical connections are designed according to IP67 protection.

[0024] The cylindrical tube 1 has water cooling and air cooling functions. The new lens compartment 4 can hold 100 new high-temperature resistant lenses. The storage compartment 5 is used to store discarded high-temperature resistant lenses. The geared motor 3 has a feedback control system. The geared motor 3 presses the discarded lenses into the storage compartment 5 after precise deceleration, and then pushes the new protective lenses out of the new lens compartment 4 and presses them into the designated position of the protective lens of the high-temperature vision camera 2. The new lenses are elastically sealed.

[0025] The vision camera 2 adopts a four-in-one optical path design, including four aiming methods: visible light, short-wave infrared, laser light source and forward eyepiece. Utilizing a 5-megapixel high-resolution camera and advanced neural network, it can collect and analyze target information in real time and extract target characteristics, achieving the technical requirements of long-term, full-process real-time operation. Production personnel can determine the operation time for changing the lens compartment based on the unit lens count and the production rhythm.

[0026] Both the new film storage compartment 4 and the storage compartment 5 are equipped with dual-color thermometers 6. These thermometers determine the temperature by measuring the ratio of infrared radiation energy in two bands of adjacent channels. The laser light source possesses unique advantages in environmental perception and system robustness. The vision camera 2 performs well under continuous disturbances and features autofocus and remote one-button fast focusing to focus on other feature points of the observed target, such as electrodes and furnace linings. The four-in-one integrated optical path design combines these four technologies to ensure clear display of the measured object at different distances, solving a key industry pain point. The laser-assisted dual-color thermometer 6 measures the temperature of the flow field within the furnace and the liquid temperature within the calibrated target range with high precision, providing operators and process engineers with reference values ​​for the molten pool temperature during production. The center point accuracy reaches ±0.3%, and the measurement accuracy of the calibrated area points reaches ±2%.

[0027] When in use, the high-temperature vision camera 2 is placed above the refining furnace cover to capture the oxidation-reduction process of molten steel and copper in a metallurgical environment for a long time. It captures the reaction state of molten steel, copper and lead in the furnace, the size of bottom blowing and side blowing stirring, the status of carbon source nozzle or submerged arc heating, the size of bottom blowing stirring, and the morphology of refining slag in real time. The vision camera 2 has the function of manual focusing and selecting target area, and can be used to observe the state of smelting slag, electrode state, and melting loss of furnace wall refractory materials.

[0028] A support plate 10 is installed in the middle of the interior of the cylindrical tube 1. The bottom of the support plate 10 is fixedly installed to the top of the reduction motor 3. A push rod 9 is installed at the output end of the reduction motor 3. The bottom of the push rod 9 is in contact with the bottom of the interior of the cylindrical tube 1. The length of the push rod 9 is greater than the shortest distance from the center line of the cylindrical tube 1 to the center line of the storage compartment 5. The length of the push rod 9 is less than the distance from the center of the cylindrical tube 1 to the side of the storage compartment 5. The diameter of the storage compartment 5 is the same as the diameter of the new film compartment 4. A wedge 8 is installed at the bottom of the interior of the cylindrical tube 1. The wedge 8 is located at the bottom of the storage compartment 5. Both sides of the wedge 8 are arc-shaped structures. The distance from the wedge 8 to the center of the cylindrical tube 1 is greater than the length of the push rod 9.

[0029] When the high-temperature lens needs to be replaced, the power supply of the geared motor 3 is turned on. When the geared motor 3 runs, the push rod 9 rotates. The rotation axis of the push rod 9 is concentric with the center line of the cylindrical tube 1. When the push rod 9 rotates to contact the old high-temperature lens at the position of the vision camera 2, the push rod 9 rotates and pushes the old high-temperature lens, causing the old high-temperature lens to gradually move towards the storage compartment 5. When the old high-temperature lens moves to contact the wedge 8, since both sides of the wedge 8 are arc-shaped, the wedge 8 moves the old high-temperature lens upward. The old high-temperature lens moves to the bottom of the storage compartment 5. Then the push rod 9 continues to rotate. Since the wedge 8 does not contact the push rod 9, the wedge 8 will not affect the forward rotation of the push rod 9. When the push rod 9 rotates to contact the high-temperature lens at the bottom of the new film compartment 4, the push rod 9 pushes the bottom high-temperature lens, causing the bottom high-temperature lens to gradually move closer to the vision camera 2, until the new high-temperature lens moves to the position of the vision camera 2, thus realizing the replacement of the high-temperature lens.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
