Description

Technical Field

[0001] The invention relates to the technical field of hot-dip galvanizing production, and in particular to a weld detection device and method for a hot-dip galvanizing coil production line. Background Art

[0002] The corrosion resistance of automobiles is directly related to the service life of automobiles. In order to improve the corrosion resistance of the car body, automobile steel plates usually choose to use relatively low-cost hot-dip pure zinc steel plates or alloyed hot-dip galvanized steel plates. In recent years, with the increasing global environmental deterioration and energy shortage problems, coupled with the improvement of vehicle collision safety standards and automobile exhaust emission regulations in various countries around the world, the strong demand of the automobile industry in terms of environmental protection, safety and energy saving has made automobile lightweighting one of the main development directions of the automobile manufacturing industry. Taking into account the cost, recycling and maintenance of automobile manufacturing, high-strength steel, especially ultra-high-strength steel, is still the preferred material for the future development of the automobile industry. Combined with the improvement of the corrosion resistance requirements of the car body, the demand for hot-dip pure zinc and alloyed hot-dip galvanized high-strength strip steel in the automobile industry is increasing rapidly year by year. In order to develop high-strength steel, especially ultra-high-strength steel hot-dip galvanized products, some new steel grades have been developed in recent years, and some new processes have also been applied. Some new processes can no longer be realized on traditional hot-dip galvanizing production lines. It is urgent to establish new production lines to meet the requirements of new processes.

[0003] Traditional hot-dip pure zinc and alloyed hot-dip galvanized strip processing lines usually include the following equipment: uncoiling - welding - entry looper - cleaning - central continuous post-processing - intermediate looper - leveling - exit looper - finishing - coiling. Some processing lines also have straightening equipment between the leveling and finishing stations, some processing lines have passivation or fingerprint resistance and other surface post-processing equipment between the leveling and finishing stations, and some processing lines have both straightening and passivation or fingerprint resistance and other surface post-processing equipment between the leveling and finishing stations.

[0004] However, at present, when the hot-dip galvanizing production line produces thick plates, each coil only takes about 10 minutes, and the overhead crane needs to frequently lift the coil; when producing thin plates, each coil takes about 25 minutes, but the production conditions are high, the production sequence changes frequently, and it is difficult to lift the coil in advance according to the production plan, and the demand for the overhead crane is tighter. In addition, for each coil produced, the entrance area will stop running for at least 2 minutes to perform necessary process operations such as welding, weld inspection, and crescent cutting of the weld edge, which affects the production efficiency of the hot-dip galvanizing production line. Summary of the invention
