The
Annealing Pickling Line incorporates an advanced Protective Atmosphere Heat Treatment System that utilizes precisely controlled nitrogen-hydrogen mixed gas (N₂-H₂, typically 5-15% H₂) to eliminate oxygen contact. This ensures complete prevention of surface oxidation and decarburization during the heating and soaking stages. With multi-zone temperature monitoring, the system maintains exact thermal profiles (700-1150℃ adjustable range, ±3℃ accuracy) for optimal material structure transformation - a critical feature of high-performance
Continuous Annealing Line operations.
Our Intelligent Temperature & Cooling System revolutionizes thermal management through:
Segmented heating design (preheating/heating/soaking sections) with independent zone control.
Precision timing control (±5s accuracy) for consistent soaking duration.
Advanced gas-mist cooling technology delivering programmable 20-150℃/s cooling rates.
Integrated over-aging treatment (300-450℃ range) to eliminate martensitic stresses.
1. Uniform microstructure development
2. Precise mechanical property control
3. Elimination of thermal deformation stresses
