Product Description
The water-cooled boiling cooling bed stands as the pinnacle of sand cooling technology in the realms of investment casting and disappearing mold casting. Despite its intricate design and rigorous demands on sand granularity, it offers unparalleled cooling efficiency, swiftly achieving the desired heat exchange via its compact cooling water pipes. This equipment, known for its higher energy consumption, nonetheless excels in meeting the stringent cooling requisites of the casting process, affirming its indispensable role in the industry.
In the intricate world of precision casting, including investment and lost foam casting, the cooling efficiency and temperature uniformity of molding sand are pivotal in determining the final casting's surface quality and dimensional precision. At the heart of high-precision casting systems lies the water-cooled boiling cooling bed, renowned for its sophisticated heat exchange mechanism and meticulous temperature control prowess. This discussion will delve into how this equipment captivates the market through its superior cooling performance, tackling challenges posed by its complex architecture and energy demands, and exploring avenues for enhanced thermodynamic optimization, precision casting adaptability, energy efficiency, and industry application.
1. Technical principles and adaptability to precision casting
For investment casting (sand particle size AFS 50-100) and lost foam casting (EPS bead particle size 0.3-0.8mm), the water-cooled boiling cooling bed achieves a remarkable technological leap with its boiling heat exchange and gradient cooling approach:
Innovative Multi-layer Water-cooled Pipe Array Design:
The water-cooled bed boasts densely configured stainless steel cooling pipes (Φ25×2mm, spaced 40mm apart) that circulate internal cooling water at a dynamic flow rate (5-15m³/h). With a pipe wall thermal conductivity of 16W/(m·K), this setup significantly outperforms ordinary carbon steel pipes, offering a 60% boost in heat exchange efficiency.
Ingeniously angled at 15°, the pipe array facilitates a vortex motion of sand flow under gravity (flow rate 0.3-0.8m/s), effectively tripling the contact area between sand particles and cooling pipes, thereby elevating cooling efficiency to an impressive 1.5-4.0t/(h·m³).
Precise Sand Particle Size Adaptation:
The fluidized bed is integrated with an adjustable grid (aperture Φ3-Φ8mm) to ensure only suitably sized sand particles (AFS 50-120) access the cooling zone, automatically diverting particles that are too coarse or fine to the regeneration system. This configuration achieves an exemplary sand temperature uniformity compliance rate of over 98% (±3ºC).
For the meticulous casting of EPS beads in lost foam, an advanced electrostatic separation module (voltage 30kV) efficiently removes residual foam particles (removal rate >95%), preventing potential blockages in the cooling pipes.
2. Core advantages and process value
Facing the challenges of a complex structure and high energy use, this sophisticated equipment demonstrates its unique value through remarkable process adaptability optimization and full life cycle cost control strategies:
Unrivaled Industry-leading Cooling Efficiency:
Achieving a remarkable 35% energy saving over traditional vibrating cooling beds, this system's energy consumption per ton of sand remains under 18kW·h. Additionally, it slashes water usage by 80% compared to pneumatic systems;
Maintaining sand particle moisture content at a stable 2.0-2.5% significantly surpasses natural cooling's uniformity by 50%, while reducing casting shrinkage defect rates to below 0.3%.
High Temperature Resilience and Enduring Design:
Crafted from Incoloy 825 nickel-based alloy, the cooling tube withstands temperatures up to 1200ºC. A protective plasma-sprayed Al2O3 coating (50μm thick) extends its life to over 8 years;
The modular tube array structure supports expedited single tube replacements, cutting maintenance time to under 30 minutes, and trimming annual maintenance costs by 45%.
Commitment to Environmental Compliance:
Engineered with precision, our closed box boasts an impressive leakage rate of less than 3mg/m³. This harmonizes perfectly with the state-of-the-art wet dust collector, which commands an air volume of 6000m³/h. Together, they ensure that the dust emission concentration is impressively maintained at a minimal level of less than 5mg/m³, providing an exceptionally clean and efficient operation.
Our cooling water circulation system is a marvel of sustainable engineering, achieving an outstanding wastewater reuse rate exceeding 95%. This system not only conserves water but also optimizes efficiency, aligning with modern environmental standards and ensuring that every drop is utilized to its fullest potential.
