Product Description
Introducing the cutting-edge Water-Cooled Boiling Cooling Bed, the pinnacle of sand cooling technology in the realm of investment casting and disappearing mold casting. This state-of-the-art equipment features an intricate network of dense cooling water pipes that masterfully facilitate rapid heat exchange. While its sophisticated design demands high energy consumption and precise sand particulate requirements, the cooling bed delivers exceptional cooling efficacy, perfectly aligned with the stringent demands of the casting process.
In the precision casting arena—encompassing investment, lost foam, and other methodologies—the importance of cooling efficiency and temperature uniformity of molding sand cannot be overstated. These factors critically influence the surface refinement and dimensional precision of castings. The water-cooled boiling cooling bed, with its innovative heat exchange structure and advanced temperature control, has emerged as the cornerstone of high-precision casting sand processing. This detailed analysis unveils the reasons behind its market prowess, examining thermodynamic optimization, precision casting adaptability, energy efficiency advancements, and its widespread industry applicability.
1. Technical principles and adaptability to precision casting
Addressing the specific needs of investment casting (AFS 50-100 sand particle size) and lost foam casting (EPS bead particle size 0.3-0.8mm), the water-cooled boiling cooling bed pioneers technological advancements with its boiling heat exchange and gradient cooling capabilities:
Multi-layer water-cooled pipe array design:
Featuring densely packed stainless steel cooling pipes (Φ25×2mm, spaced 40mm), the system utilizes internally circulating cooling water (flow rate 5-15m³/h) and boasts a pipe wall thermal conductivity of 16W/(m·K), enhancing heat exchange efficiency by 60% compared to standard carbon steel pipes.
Ingeniously stacked at a 15° angle, the pipe array induces a vortex motion in the sand flow (velocity 0.3-0.8m/s), tripling the contact surface area between sand particles and cooling pipes, thus achieving cooling efficiencies of 1.5-4.0t/(h·m³).
Precise adaptation of sand particle size:
The fluidized bed is fitted with an adjustable grid (aperture Φ3-Φ8mm) to ensure that only suitably sized sand particles (AFS 50-120) proceed to the cooling zone, while oversized or undersized particles are automatically redirected to the regeneration system, ensuring a sand temperature uniformity compliance rate of over 98%, with a deviation of just ±3ºC.
For lost foam casting with EPS beads, an electrostatic separation module (voltage 30kV) efficiently eliminates residual foam particles (achieving a removal rate exceeding 95%) to prevent potential blockages within the cooling pipes.
2. Core advantages and process value
Despite the inherent challenges of its complex structure and high energy demand, the equipment delivers unparalleled value through optimized process adaptability and comprehensive life cycle cost management:
Industry-leading cooling efficiency:
Achieve remarkable energy savings of 35% compared to traditional vibrating cooling beds (energy consumption per ton of sand ≤18kW·h), and reduce water usage by an impressive 80% compared to pneumatic cooling systems;
The sand particles maintain a stable moisture content of 2.0-2.5%, enhancing uniformity by 50% over natural cooling methods, while casting shrinkage defects plummet to below 0.3%.
High temperature resistant and long-lasting design:
Crafted from Incoloy 825 nickel-based alloy, the cooling tubes resist temperatures up to 1200ºC, further protected by a plasma-sprayed Al2O3 coating (50μm thickness), ensuring a robust service life exceeding 8 years.
The modular design of the tube array accommodates single tube replacement, minimizing maintenance time to under 30 minutes and slashing annual maintenance costs by 45%.
Environmental compliance:
Experience the pinnacle of air purification with our closed box system, boasting an impressively low leakage rate of less than 3mg/m³. Paired seamlessly with a state-of-the-art wet dust collector, it commands an impressive air volume of 6000m³/h, ensuring that the dust emission concentration remains astonishingly low at under 5mg/m³. This powerful duo guarantees cleaner air and a healthier environment for all.
Embrace sustainability with our advanced cooling water circulation system, designed to maximize efficiency and eco-friendliness. With a remarkable wastewater reuse rate exceeding 95%, our system not only conserves precious resources but also delivers performance excellence, making it an ideal choice for those committed to environmental responsibility.
