Description

technical field [0001] This patent application belongs to the technical field of automatic system optimization of a cold rolling galvanizing production line, and more specifically relates to a method for optimizing transmission speed and tension compensation of an old galvanizing production line. Background technique [0002] Since many domestic galvanizing production lines have been put into production, the transmission system has only been optimized for speed at the beginning of the construction of the production line, and has never been optimized for speed and tension compensation after that. Many parameters are no longer suitable for the current production and actual conditions of the equipment. Yes, the galvanizing production line that has been built for more than ten years is facing this problem. It is necessary to optimize the speed of the main and auxiliary transmissions, the optimization of tension compensation and the construction of an on-site speed feedback mechan...

Problems solved by technology

[0002] Since many galvanizing production lines in China have been put into production, the transmission system has only been optimized for speed at the beginning of the construction of the production line, and has never been optimized for speed and tension compensation after that. Many parameters are no longer suitable for the current production and actual equipment conditions. Yes, the galvanizing production line that has been built for more than ten years is facing this problem. It is necessary to optimize the speed of the main and auxiliary transmissions, tension compensation optimization and the construction of an on-site speed feedback mechanism, otherwise the entire production line will not be able to upgrade the old production line. The transmission speed response and dynamic control function cannot support new product development and guarantee the product quality of original products.
