| No.3 Tandem Cold Mill with Pickling Line (3PLCM) | Hot rolled coils will be charged at the entry side of pickling line. Through the process of welding, tension leveling, jet-flow pickling, the strip surface will be continuously cleaned up. In addition, this line utilizes side trimmer to satisfy the width requirement. Furthermore, the strip will be sent through 5-stand 6-high tandem cold mill, which uses auto gauge control to achieve the product thickness. By the aid of auto shape control and edge drop control, the higher quality of the shape and edge drop can be performed. Finally, the strip will be recoiled to become the cold rolled coils.
