On August 10, 2020, the finished product area of the newly built workshop of Panzhihua Iron and Steel Group Chengdu Plate Co., Ltd. was crowded. At 16:30, as a silver galvanized coil was slowly transferred from the unit, the moment it landed, everyone Cheers, the first volume of 1550 (aluminum) zinc plating unit of Panzhihua Iron and Steel Group Chengdu Plate Co., Ltd. successfully rolled off the assembly line, marking the one-time success of the thermal load test of the continuous hot-dip (aluminum) zinc unit contracted by Huangshi Shanli, and the unit officially entered Trial production stage.

 

  This unit is a key project of Panzhihua Iron and Steel Group. It was built by Huangshishan with great efforts. It is responsible for the whole process from design, construction to commissioning. It adopts advanced industry technology. From uncoiling to finished product packaging, it has achieved a high degree of automation and efficiency. Shanli has accumulated technical advantages in the industry for many years. At the same time, the unit can produce two kinds of galvanized and galvanized products. The seamless switching of the process has been realized, which meets the needs of Pangang Group to produce multiple products in one unit.

 The design capacity of the unit is 320,000 tons/year, and it has the functions of annealing reduction, hot-dip (aluminum) zinc, smoothing, stretching, self-lubricating/fingerprint resistance, oil coating, etc. The raw materials are cold-rolled hardened steel coils SPCC, SPCD , IF, the specification is (0.25-1.2)mm*(720-1500)mm, and the design process speed of the unit is Max.160m/min. According to the function of the unit and the strip processing sequence, the unit can be divided into the entrance section, the process section and the 岀 Oral segment. The entrance section mainly includes uncoiling, shearing, and welding to provide continuous strips for the process section; the process section mainly includes degreasing, annealing reduction section, (aluminum) zinc plating section, smoothing and stretching section, self-lubricating or fingerprint-resistant section, etc. Finish the technological processing of the strip; the exit section finishes the sub-coiling and coiling of the strip.

 The successful commissioning of the 1550 (aluminum) zinc plating line of Panzhihua Iron and Steel Group Chengdu Plate Co., Ltd. is another masterpiece of Shanli Company after the successful commissioning of the two galvanizing lines of Hebei No. 3 Steel and the Anyang Shenlong galvanizing line in the past year. . In the future, more projects under construction will be put into production one after another. The successive projects fully reflect the leading advantage and comprehensive strength of Shanli Company in the industry. Looking forward to the future, all Shanli people will continue to explore, practice and innovate, and work together to build the company into a first-class supplier of technical equipment!
