Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical equipment, and particularly to an automatic adjustment device for the position of a furnace nose based on three-dimensional detection. Background Art

[0002] In many high-end manufacturing industries, such as the automotive and home appliance industries, the quality requirements for products are very strict. The position of the furnace nose has an important impact on the surface quality of the product, and position deviation may cause defects in the product. Three-dimensional detection technology can accurately measure the position of the furnace nose, and the automatic adjustment device can make timely adjustments according to the detection results to ensure that the furnace nose is in the best position, thereby improving the quality of the product. Taking the production of automotive panels as an example, the requirements for surface quality are extremely high, and precise control of the furnace nose position is crucial for producing high-quality automotive panels. The furnace nose is widely used in continuous annealing production lines, hot-dip galvanizing production lines, etc. in industries such as steel and non-ferrous metals. In the continuous annealing production line, the accuracy of the furnace nose position directly affects the running stability of the steel strip in the furnace and the annealing quality.

[0003] In the continuous galvanizing production line, the position of the furnace nose has a crucial impact on the galvanizing quality. If the position of the furnace nose is deviated, it may cause the strip steel to collide and scratch with the inner wall of the furnace nose, affecting the surface quality of the strip steel, and will also cause the imbalance of the furnace atmosphere control, thereby affecting the quality and uniformity of the galvanized layer. Traditional adjustment of the furnace nose position often relies on manual experience and regular manual measurement. This method is inefficient and difficult to guarantee accuracy, and cannot respond in real time to position changes caused by factors such as equipment vibration and thermal deformation during the production process.

[0004] Therefore, it is very necessary to propose an automatic adjustment device for the position of the furnace nose based on three-dimensional detection in this application to solve the problems in the background.

[0005] 1. Patent document CN108342673B discloses an on-line position adjustment device for a zinc boiler nose. The above patent realizes the dynamic monitoring of the levelness of the furnace nose and can automatically adjust the levelness of the furnace nose, but the above patent cannot realize the function of accurately obtaining its three-dimensional spatial position information by real-time monitoring the furnace nose.

[0006] 2. Patent document CN114998414B discloses a method, device and medium for three-dimensional dimension measurement of parts based on point cloud data. The above patent realizes two measurement programs that can perform three-dimensional measurement of target parts. Users can use this program to perform preliminary automatic measurement and manual measurement at specified positions on the target parts, providing a convenient and practical measurement method for three-dimensional target detection; at the same time, using this program is not affected by the placement position of the target part, and better solves the problem of the placement position of the target brought by the two-dimensional measurement method, but the above patent cannot realize the function of seamless switching and collaborative precise adjustment.

[0007] 3. Patent document CN110134234B discloses a method and device for three-dimensional object positioning. The above patent realizes the adaptive adjustment of virtual objects according to the dynamic changes of three-dimensional objects in a single-camera scenario, but the above patent cannot realize the function of measuring liquid level.

[0008] 4. Patent document CN107354288B discloses a furnace nose device with an annular slag discharge groove. The above patent realizes the effective removal of zinc ash around the strip in the furnace nose, thus preventing the zinc ash from flowing back to the strip area and causing zinc ash defects on the plate surface, and greatly extending the service life of the furnace nose device. However, the above patent cannot realize the function of automatically adjusting the position of the furnace nose.

[0009] In summary, the above patents cannot realize the functions of real-time monitoring of the furnace nose to accurately obtain its three-dimensional spatial position information, seamless switching and coordinated precise adjustment, measuring liquid level, and automatically adjusting the position of the furnace nose, resulting in rough traditional positioning detection methods, low production efficiency, difficult adjustment due to load changes, unawareness of abnormal fluctuations in liquid level data, and cumbersome simple mechanical operations.

[0010] Therefore, this application proposes a furnace nose position automatic adjustment device based on three-dimensional detection that can realize the functions of real-time monitoring of the furnace nose to accurately obtain its three-dimensional spatial position information, seamless switching and coordinated precise adjustment, measuring liquid level, and automatically adjusting the position of the furnace nose.
