Description

Technical Field

[0001] The invention relates to the technical field of metallurgical equipment, and in particular to a device for automatically adjusting the position of a furnace nose based on three-dimensional detection. Background Art

[0002] In many high-end manufacturing industries, such as automobiles and home appliances, 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 based on 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 automobile panels as an example, the requirements for surface quality are extremely high. The precise control of the position of the furnace nose is crucial to the production of high-quality automobile panels. The furnace nose is widely used in continuous annealing production lines, hot-dip galvanizing production lines, etc. in the steel, non-ferrous metals and other industries. In the continuous annealing production line, the accuracy of the position of the furnace nose directly affects the running stability and annealing quality of the steel strip in the furnace.

[0003] In a continuous galvanizing production line, the position of the furnace nose has a crucial impact on the quality of galvanizing. If the position of the furnace nose is deviated, it may cause the strip to collide with and scratch the inner wall of the furnace nose, affecting the surface quality of the strip, and will cause the atmosphere control in the furnace to be unbalanced, thereby affecting the quality and uniformity of the galvanized layer. Traditional furnace nose position adjustment often relies on manual experience and regular manual measurement. This method is inefficient and difficult to guarantee accuracy. It 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 necessary for the present application to propose an automatic furnace nose position adjustment device based on three-dimensional detection to solve the problems in the background.

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

[0006] 2. Patent document CN114998414B discloses a method, device and medium for measuring the three-dimensional dimensions 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 of target parts and manual measurement of specified positions, providing a convenient and practical measurement method for three-dimensional target detection; at the same time, the use of this program is not affected by the placement of the target parts, and better solves the target placement caused by the two-dimensional measurement method, but the above patent cannot realize the function of seamless switching and coordinated precise adjustment.

[0007] 3. Patent document CN110134234B discloses a method and device for locating three-dimensional objects. The above patent realizes adaptive adjustment of changes of virtual objects according to dynamic changes of three-dimensional objects in a single camera scene, 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 can effectively remove zinc ash around the strip steel in the furnace nose, thereby preventing the zinc ash from flowing back to the strip steel area and causing zinc ash defects on the plate surface, thereby 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 patent 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, liquid level measurement and automatic adjustment of the furnace nose position, resulting in low production efficiency due to the roughness of the traditional positioning detection method, difficulty in adjustment due to load changes, failure to detect abnormal fluctuations in the liquid level data, and cumbersome simple mechanical operation; To this end, the present application proposes an automatic furnace nose position adjustment device based on three-dimensional detection, which 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, liquid level measurement and automatic adjustment of the furnace nose position.
