Jining News Network (Correspondents Dong Mingzhu and Jiang Dandan) — The Jiaxiang Kelonpu Alloy New Material R&D and Production Project promotes the transformation and upgrading of the manufacturing industry and high-quality development through fully automated and intelligent control throughout the process.
Jiang Dandan, reporter from Jiaxiang County Media Center, said: “At the site of the Kelonpu Alloy New Material R&D and Production Project, everyone can see that the newly installed production lines for zinc-aluminum-magnesium sheets and chromium plating are already in the debugging stage. Once the project is put into production, it is expected to have an annual output of 400,000 tons of zinc-aluminum-magnesium sheets, 200,000 tons of chromium-plated sheets, and 24,000 tons of polyferric chloride. The first phase is expected to achieve an annual output value of 2.6 billion yuan, tax and profit of 470 million yuan, and create 270 jobs.”
The project has an investment of 860 million yuan and includes 20 new production lines for zinc-aluminum-magnesium sheets, hydrochloric acid pickling, and other processes. It utilizes advanced automated control systems for rolling mill thickness and sheet shape. The produced zinc-aluminum-magnesium alloy has 10 to 20 times the heat resistance of traditional galvanized steel sheets, with high flat corrosion resistance and self-healing at cut edges. It is widely used in building steel structures, medium-to-large fixed-wing drones, high-speed train interior shells, and automotive panels.
Cao Zhuang, head of the Kelonpu Alloy New Material R&D and Production Project, stated: “We have adopted globally leading six-stand rolling technology and new equipment. Compared with the traditional five-stand rolling, it can increase production efficiency by 30% and save 30% energy. The project covers acid pickling, continuous rolling, annealing, degreasing, double-frame leveling, coating and plating, making it the most comprehensive process for a single domestic enterprise. The produced zinc-aluminum-magnesium coated sheets and chromium-coated sheets include more than 60 varieties ranging from 0.08 to 6.0 mm, making it the project with the most product varieties for a single domestic enterprise.”
Gu Wei, deputy director of the Comprehensive Department of Jiaxiang Economic Development Zone, said: “We track the project through a closed-loop management approach. For bottlenecks in the project, we promptly hold discussions, conduct frontline research, and implement targeted measures to shift service efficiency from ‘one-time benefits’ to ‘comprehensive improvement,’ effectively promoting the orderly advancement of the project.”
