Cracks/bubbles/performance fluctuations? A complete guide to Mingtai 5052-H32 aluminum plate production problems
In the production process of 5052-H32 aluminum plates, cracks, bubbles, and performance fluctuations are the three major problems that plague many companies. As an industry benchmark with more than 20 years of deep cultivation in the aluminum processing field, Mingtai Aluminum is driven by technological innovation, combined with more than a thousand experimental data and millions of tons of production experience, to provide you with this targeted solution guide.
1. Crack prevention and control: Eliminate quality risks from the source
Source of the problem
● Ingot composition segregation leads to stress concentration
● Rolling temperature gradient exceeds the material tolerance threshold
● Improper annealing process parameters of finished products
Mingtai solution
1. Precise composition control: Use a spectrometer for real-time detection to ensure that the Mg/Mn ratio is controlled within the golden range of 2.2-2.8%
2. Intelligent rolling system: Equipped with a laser temperature measuring device to achieve ±5℃ temperature fluctuation control, combined with a graded rolling process
3. Three-stage annealing: Develop a “low-temperature pre-recovery + medium-temperature recrystallization + high-temperature stabilization” composite annealing technology to eliminate residual stress
Results: The crack incidence rate has dropped from the industry average of 3.2% to below 0.8%
2. Bubble elimination: Create perfect surface quality
Source of the problem
● Incomplete smelting and degassing leads to residual hydrogen
● Improper mold lubrication produces gas encapsulation
● Rolling coiling tension control is inaccurate
Mingtai solution
1. Six-stage degassing system: rotary spraying + ultrasonic vibration + vacuum refining three-stage smelting degassing, hydrogen content is controlled below 0.12ml/100g
2. Nano-lubricating coating: self-developed graphene-based lubricant to achieve zero residual gas on the mold contact surface
3. Dynamic tension compensation: equipped with a servo control system with a response frequency of 200Hz to ensure that the winding tension fluctuation is <3%
Results: The surface bubble defect rate has dropped by 85%, reaching the A-level surface standard
III. Stable performance: Overcoming the fluctuation curse
Source of the problem
● Uneven distribution of alloy elements
● Unstable grain size control
● Aging process parameter drift
Mingtai solution
1. Electromagnetic stirring technology: Apply variable frequency electromagnetic field during the smelting stage to achieve a composition uniformity of 98.6%
2. Grain refinement engineering: Add Sc/Zr composite refiner, cooperate with gradient cooling process, and control the grain size at 80-120μm
3. Intelligent aging system: PID algorithm is used to automatically control the aging temperature curve to ensure that the fluctuation range of mechanical properties is ≤3%
Results: The tensile strength is stable at 285-295MPa, and the elongation fluctuation range is controlled within 1.2%
