<p>A flexible thin strip steel processing line suitable for producing various high-strength steel is set as follows: an uncoiling and washing station, a heating station, a soaking station, a retarded cooling station, a gas jet cooling station, a water quenching cooling station, an acid washing station, a reheating station, an overaging station, a final cooling station, a flattening station, a finishing station, a greasing station and a coiling station in turn. Additionally, a plating station is set and connected with the uncoiling and washing station, the acid washing station and the reheating station separately by connecting passages. A hot dip galvanizing and alloyed annealing of galvanizing coating station is set, which is connected with the reheating station by a hot dip galvanizing furnace nose and with a post-galvanizing cooling station and the final cooling station by connecting passages. A Passivating and other post-treatment station is set and connected with the plating station, the flattening station and the finishing station separately by connecting passages. The reheating station is connected with the overaging station by a movable by-pass passage. The production of common cold rolled plate, hot dip galvanizing and alloyed annealing sheet of galvanizing coating, galvanized steel plate and nickel plating plate, especially the production of cold rolled plate, galvanized steel plate and hot dip galvanizing and alloyed annealing sheet of galvanizing coating in ultra high strength grade, are integrated into one set. The strip steel processing line achieves flexible production.</p> |
