The Huangshi Shanli Climbing Steel continuous hot-dip galvanizing (aluminum) zinc unit project has been successfully put into production

On August 10, 2020, the newly built workshop finished product area of Panzhihua Iron and Steel Group Chengdu Sheet Co., Ltd. was bustling with people. At 4:30 pm, as a roll of glittering aluminum-zinc coated steel slowly moved from the production line and landed, everyone cheered. The first roll of the Panzhihua Iron and Steel Group Chengdu Sheet Co., Ltd. 1550 galvanizing (aluminum) zinc production line was successfully produced, marking the successful completion of the hot load test of the continuous hot-dip galvanizing (aluminum) zinc production line undertaken by Huangshi Shanli, and the production line officially entered the trial production stage.

This production line is a key project of Panzhihua Iron and Steel Group, and was meticulously crafted by Huangshi Shanli, who was responsible for the entire process from design and construction to commissioning. It adopts advanced industry technologies, and achieves high automation and efficiency from uncoiling to finished product packaging, demonstrating Shanli's accumulated technological advantages in the industry over the years. At the same time, this production line can produce both galvanized and aluminum-zinc coated products, and seamlessly switches between processes, meeting the needs of Panzhihua Iron and Steel Group for one production line to produce multiple products.

The production line has a design capacity of 320,000 tons/year, and has functions such as annealing and reduction, hot-dip galvanizing (aluminum) zinc, leveling, straightening, self-lubrication/fingerprint resistance, and oiling. The raw material types are cold-rolled hard-tempered steel coils SPCC, SPCD, IF, with specifications of (0.25-1.2)mm*(720-1500)mm, and the design process speed is Max.160m/min. According to the functions of the production line and the processing order of the steel strip, the production line can be divided into an inlet section, a process section, and an outlet section. The inlet section mainly includes uncoiling, shearing, and welding, continuously supplying strip to the process section; the process section mainly includes degreasing, annealing and reduction section, galvanizing (aluminum) zinc section, leveling and straightening section, self-lubrication or fingerprint-resistant section, etc., to complete the process treatment of the steel strip; the outlet section completes the recoiling and coiling of the strip.

The successful commissioning of the Panzhihua Iron and Steel Group Chengdu Sheet Co., Ltd. 1550 galvanizing (aluminum) zinc production line is another masterpiece of Shanli Company following the successful commissioning of two galvanizing lines in Hebei Sangang and Anyang Shenlong galvanizing line within the past year. More projects under construction will be put into production successively. The continuous projects fully demonstrate Shanli Company's leading advantages and comprehensive strength in the industry. Looking to the future, all Shanli people will continue to explore, practice and innovate, and work together to build the company into a first-class technology equipment supplier!
