FLEXIBLE STRIP STEEL PROCESSING LINE SUITABLE FOR PRODUCING VARIOUS KINDS OF HIGH-STRENGTH STEELS

摘要

Flexible strip steel processing line suitable for producing various kinds of high-strength steels, includes decoiling and cleaning, heating, soaking and slowly cooling stations in turn,and then arranging high hydrogen jet cooling station and water quenching station in parallel; the high hydrogen jet cooling station is followed by reheating, overaging, final cooling, leveling up, finishing station, oil coating and batching station; the water quenching station is followed in turn by pickling station, electroplating station;the hot galvanizing station is arranged behind the reheating station;the galvannealing station is arranged behind the hot galvanizing station, and is connected with the final cooling station by setting connection pipeline;the pickling station and electroplating station separately connect with reheating station by connection pipeline;the electroplating station directly connects with decoiling and cleaning station by connection pipeline;the water quenching station connects with slowly cooling station by fixed bypass line; reheating station connects with overaging station by movable bypass line. The processing line realizes flexible production by production of various high strength steels to form an assembling unit.
