The qualified rate increased by 20%! Mingtai analyzes the secret of optimizing the production process parameters of 5052 aluminum plates

In the aluminum processing industry, a 0.1% increase in the yield rate means a huge cost advantage. After three years of research and development, Mingtai Aluminum has systematically optimized the production process of 5052 aluminum plates and successfully increased the overall qualified rate from 82% to 98.6%. The following reveals the optimization strategy of key process parameters:
1. Melting parameters: Accurately control alloy genes
Optimization core
● Melting temperature: Adjust the traditional 750℃±10℃ range to 735℃±5℃, reducing Mg element burnout by 2.3%
● Casting speed: Use frequency conversion control to control speed fluctuation within 0.8m/min, and increase grain size uniformity by 40%
● Cooling gradient: Develop a stepped water cooling system to achieve gradient control of mold temperature from 680℃ to 450℃, reducing crack tendency

2. Rolling parameters: Shaping a perfect plate shape
Breakthrough point
● Pass reduction: The first pass is adjusted from 25% to 18%, and the intermediate annealing process is used to eliminate internal stress
● Rolling speed: The key pass speed is increased to 8m/min, and high-frequency induction heating is used to achieve dynamic recrystallization
● Coiling tension: A tension model is established using a neural network algorithm to adjust the coiling tension Fluctuation is controlled within 2%
3. Heat treatment parameters: awakening material performance
Innovation points
●Pre-aging process: pre-aging at 460℃ for 1h to promote uniform precipitation in the GP zone
●Main aging curve: develop a three-level aging process (120℃/8h+160℃/4h+190℃/2h)
●Intergranular corrosion control: add 0.08% Sc element, cooperate with T651 process, so that the exfoliation corrosion level reaches EXCO≥EB
4. Intelligent detection: full-cycle quality protection
Support system
●Online detection system: equipped with laser thickness gauge (accuracy ±0.5μm), eddy current flaw detector (defect recognition rate 99.2%)
●AI quality prediction: establish a digital twin model to achieve surface quality and mechanical properties 30 minutes in advance
●Traceability cloud platform: generate 238 quality data points for each roll of product, supporting full life cycle traceability
