Unveiling China's first hydrogen powered iron art intelligent manufacturing production line put into operation

Full process technical analysis
1. Raw material innovation:
Using NM450 wear-resistant steel (GB/T24186) developed by Ansteel Group, carbon emissions are reduced by 72% through hydrogen reduction process, and the material hardness reaches HRC52, far exceeding traditional electric furnace steel.
2. Breakthrough in Intelligent Manufacturing Systems:
-Laser cutting: The TruLaser 8000 series equipment from Tongkuai achieves an accuracy of ± 0.005mm, with a cut oxide layer thickness of ≤ 10 μ m
-Robot welding: ABB dual arm robot equipped with visual positioning system, the qualification rate of weld seam inspection has increased from 82% to 99.7%
-Surface treatment: Introducing German Henkel nano ceramic coating technology (patent DE102022113467), salt spray resistance test exceeded 5000 hours
3. Quality control system upgrade:
Establish 135 quality control nodes from raw material entry to finished product exit, with key indicators including:
-Stress relief: using spectral harmonic vibration aging technology, residual stress ≤ 15MPa
-Rust prevention test: Passed ASTM B117 salt spray test for 2000 hours without rust spots
-Load test: 20 ton press machine simulates 30-year natural wind load
Application scenario expansion
-Urban Sculpture: The installation of "Time and Space Gate" in Shanghai Lujiazui Financial City, using a 304 stainless steel honeycomb structure, resistant to a level 16 typhoon
-Home art: Italian Poltrona Frau custom iron screen, incorporating cloisonn é wire cutting technology, priced at € 25000 per item
Industry certification
Obtained T Ü V Rheinland's "Zero Defect Factory" certification, products are exempt from inspection for export to 78 countries, and overseas orders will increase by 210% year-on-year in 2024.
