I. Industry Insight: Solution Heat Treatment Bottlenecks for Aluminum Structural Components

In high-precision manufacturing fields such as automotive lightweighting, aerospace, and rail transit, aluminum alloy die castings and plates are extensively used. To substantially enhance the mechanical strength, hardness, and corrosion resistance of aluminum components, they must undergo rigorous Solution Heat Treatment followed by rapid quenching.

However, aluminum alloy solution processing poses two extremely strict engineering challenges:

1. Extreme Temperature Uniformity: In the late soaking stage, the temperature variance throughout the furnace working zone must be kept minimal to prevent local over-burning or insufficient solutionization.

2. Strict Quenching Transfer Window: Once heating and soaking are finalized, the components must be rapidly transferred and fully submerged from the high-temperature furnace chamber into the quenching medium within a golden window (typically less than 12 seconds) to lock in the required supersaturated solid solution phase.

Conventional box furnaces or standard pit furnaces feature slow transfer mechanisms and large thermal losses, failing to meet high-grade alloy standards. Addressing the global high-end non-ferrous metal processing sector, WONDERY launched the intelligently controlled, rapid-discharge Vertical Aluminum Alloy Solution Furnace System ($varnothing1200 times 1500text{ mm}$) (Proposal No: WDL2606116NH) , achieving a premium international turnkey delivery at the facility of client GAL in India.

II. Technical Solutions and Process Architecture

1. Detailed Description of Core Process Units

• Top Vertical Furnace Body Unit: The furnace working zone features an effective size of varnothing1500 times 1900 , enclosed by a240 high-density standard refractory ceramic fiber blanket insulation lining. This layout fully eliminates thermal bridging, containing the external shell temperature rise within ambient +$25^{circ}text{C}$. The heating elements utilize 0Cr25Al5 high-grade anti-oxidation resistance bands , evenly distributed across all four inner walls, secured via high-temperature ceramic screws , and wired in a Y-configuration across 2 independent temperature control zones. A top-mounted 5.5 6-pole powerful hot air circulation fan works in tandem with a  SUS304 stainless steel air deflector system to ensure the furnace temperature uniformity is strictly within text during thermal soaking, with a control accuracy under

• High-Speed Dual-Speed Hoisting Mechanism (1T Winch): The structural material frame is rated for a load capacity of le 1000 (basket dimensions of varnothing1200 times 1500. To balance stable suspension with extreme quenching transitions, WONDERY implemented a fast-lowering and slow-raising dual-speed winch profile : the rapid downward transfer velocity reaches $22text{ m/min}$. Paired with a pneumatic cylinder-actuated slide-open door that unlatches in just 4 seconds , the system guarantees a total elapsed time of from the initial furnace door opening to complete immersion in the quenching medium, delivering industry-leading performance that easily surpasses the 12-second threshold.

•  

  Multi-Dimensional Mobile Quenching Tank: Positioned directly beneath the elevated vertical furnace, the mobile quenching tank is driven by a motor reducer via a wheel-and-chain assembly , traveling smoothly into position at. Heavy-duty limit switches securely lock its travel boundaries. The tank is outfitted with a 60kW independent electrical heating system and a2.2 high-flow water circulation pump to break up any vapor blankets forming around the hot castings, ensuring an instantaneous and uniform thermal exchange.

2. Rittal-Standard Digitalized Control Cabinet System

• High-Precision Power Regulation: Each heating zone is managed by a Japanese Shimaden SRS13A high-precision intelligent program meter. These meters utilize three-phase SCR power regulators with zero-crossing triggering, preventing electrical spikes on the plant grid and yielding rapid data control feedback.

• HMI and Data Visualization: The core operation terminal employs a 10-inch Kunlun Tongtai high-resolution industrial touchscreen. This enables operators to program, monitor, record, and extract full heat treatment process curves , backed by user password access privileges.
