Product Description
The water-cooled boiling cooling bed stands as the premier choice for sand cooling in investment casting and disappearing mold casting. Featuring a densely arranged cooling water pipe system, it ensures rapid heat exchange, delivering an exceptional cooling effect that meets the rigorous demands of the casting process. While it features a complex structure and higher energy consumption, its unparalleled performance in maintaining the integrity of particle size and cooling efficacy makes it indispensable.
In the realm of precision casting, including investment casting and lost foam casting, the cooling efficiency and temperature consistency of molding sand are pivotal to achieving superior surface quality and precise dimensional accuracy. The water-cooled boiling cooling bed, with its exceptional heat exchange design and precise temperature control, has cemented its role as the cornerstone of high-precision casting sand systems. This piece delves into its market dominance fueled by outstanding cooling performance, addressing challenges of complexity and energy demands by exploring thermodynamic optimization, precision casting compatibility, energy efficiency advancements, and widespread industry applications.
1. Technical principles and adaptability to precision casting
Tailored for the unique demands of 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 revolutionary advancements through its boiling heat exchange and gradient cooling processes:
Multi-layer water-cooled pipe array design:
The cooling infrastructure boasts densely packed stainless steel pipes (Φ25×2mm, spaced at 40mm apart), with internal circulating water (flow rate 5-15m³/h) and a thermal conductivity of 16W/(m·K) that surpasses ordinary carbon steel pipes by 60% in heat exchange efficiency.
Ingeniously angled at 15°, the pipe array facilitates a vortex motion of sand under gravity (flow rate 0.3-0.8m/s), tripling the contact area with cooling pipes and achieving a remarkable cooling efficiency of 1.5-4.0t/(h·m³).
Precise adaptation of sand particle size:
The fluidized bed is equipped with an adjustable grid (aperture Φ3-Φ8mm) designed to permit only qualified sand particles (AFS 50-120) into the cooling zone. Oversized or undersized particles are effectively rerouted to the regeneration system, ensuring a sand temperature uniformity compliance rate exceeding 98%, within ±3ºC.
For EPS beads utilized in lost foam casting, an integrated electrostatic separation module (voltage 30kV) is deployed to efficiently extract residual foam particles, achieving a removal rate over 95%, thereby preventing cooling pipe blockages.
2. Core advantages and process value
Amidst the intricate design and higher energy usage, the equipment delivers unmatched value through process adaptation and comprehensive lifecycle cost management:
Industry-leading cooling efficiency:
Realize up to 35% energy savings compared to conventional vibrating cooling beds (energy consumption per ton of sand ≤18kW·h) and an impressive 80% water savings over pneumatic cooling systems.
Achieve a stable sand moisture content of 2.0-2.5%, enhancing homogeneity by 50% over natural cooling methods, while reducing casting shrinkage defects to below 0.3%.
High temperature resistant and long-lasting design:
Constructed from Incoloy 825 nickel-based alloy, the cooling tube withstands temperatures up to 1200ºC. Enhanced with a 50μm Al2O3 plasma-sprayed coating, it assures a service life surpassing 8 years.
The modular tube array allows for swift single-tube replacement, minimizing maintenance time to under 30 minutes, and reducing annual maintenance costs by 45%.
Environmental compliance:
The expertly engineered closed box system boasts an impressive leakage rate of less than 3mg/m³, seamlessly partnering with the efficient wet dust collector, which commands an air volume of 6000m³/h. Together, they ensure that the dust emission concentration is maintained below an exceptional 5mg/m³;
Our state-of-the-art cooling water circulation system is designed with sustainability in mind, achieving a remarkable wastewater reuse rate exceeding 95%, thus promoting an eco-friendly and resource-efficient operation.
