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.
This integrated approach ensures the Annealing Line achieves:
1. Uniform microstructure development
2. Precise mechanical property control
3. Elimination of thermal deformation stresses
For demanding applications requiring mirror-finish surfaces, our Continuous Bright Annealing Machine variant adds enhanced atmosphere purity controls and specialized cooling protocols. The complete
Continuous Annealing And Acid Washing Production Line solution combines these advanced annealing capabilities with inline pickling for ultimate material quality.
