Product Description
The Water-Cooled Boiling Cooling Bed stands as the pinnacle of sand cooling solutions in the realms of investment casting and disappearing mold casting. With its ingeniously dense cooling water pipe system, this sophisticated apparatus ensures rapid and efficient heat exchange, delivering unparalleled cooling performance. Despite its complex architecture and high energy consumption, the system precisely caters to the sand's particle size, ensuring optimal cooling to meet the stringent demands of the casting process.
In the specialized arena of precision casting, encompassing both investment and lost foam casting, the water-cooled boiling cooling bed plays a pivotal role. Its cooling efficiency and uniform temperature distribution are critical in achieving superior surface quality and dimensional fidelity in castings. Distinguished by its one-of-a-kind heat exchange structure and precise temperature regulation, this equipment is the linchpin of any high-precision casting sand processing setup. This discussion will delve into how this equipment captures market attention through stellar cooling capabilities, overcoming the intricacies of its structure and energy requirements by focusing on thermodynamic optimization, precision casting adaptability, energy efficiency enhancements, and broad industry applications.
1. Technical Principles and Precision Casting Adaptability
Catering to the unique demands of investment casting (for sand particle size ranging AFS 50-100) and lost foam casting (EPS bead particle size from 0.3-0.8mm), the water-cooled boiling cooling bed heralds a groundbreaking leap in technology with its boiling heat exchange and gradient cooling capabilities:
Multi-Layer Water-Cooled Pipe Array Design:
The system boasts an array of tightly arranged stainless steel cooling pipes (dimensions Φ25×2mm, spaced 40mm apart), which circulate cooling water internally at flow rates of 5-15m³/h. The pipes exhibit a thermal conductivity of 16W/(m·K), offering a 60% increase in heat exchange efficiency compared to standard carbon steel pipes.
Arranged at a strategic 15° angle, the pipe array induces a vortex motion in the sand flow via gravity (flow rate 0.3-0.8m/s), significantly amplifying the contact area between sand particles and cooling pipes—tripling it to be exact—and achieving outstanding cooling efficiency levels of 1.5-4.0t/(h·m³).
Precise Sand Particle Size Adaptation:
Equipped with an adjustable grid (aperture Φ3-Φ8mm), the fluidized bed meticulously ensures only properly sized sand particles (AFS 50-120) enter the cooling zone. Particles that are too coarse or too fine are deftly redirected to the regeneration system, ensuring sand temperature uniformity compliance (±3ºC) exceeding 98%.
For EPS beads employed in lost foam casting, an innovative electrostatic separation module (operating at 30kV) effectively removes residual foam particles, achieving a removal rate of over 95%, thereby preventing cooling pipe obstructions.
2. Core Advantages and Process Value
Despite battling the challenges of intricate structures and high energy demands, this superior equipment showcases its exceptional value through enhanced process adaptability and strategic full life cycle cost management:
Industry-Leading Cooling Efficiency:
Experience a remarkable 35% reduction in energy use compared to traditional vibrating cooling beds, with energy consumption per ton of sand maintained at ≤18kW·h. Furthermore, it conserves a staggering 80% of water compared to pneumatic cooling systems;
The sand particles maintain a stable moisture content between 2.0-2.5%, enhancing uniformity by 50% compared to natural cooling methods and reducing casting shrinkage defect rates to below 0.3%.
High-Temperature Resistant and Durable Design:
Constructed from Incoloy 825 nickel-based alloy, the cooling tube withstands temperatures up to 1200ºC. Its surface is fortified with an Al2O3 plasma-sprayed coating (50μm thick), ensuring a service life extending beyond 8 years;
The modular array structure allows for the swift replacement of individual tubes, with maintenance tasks completed in under 30 minutes, slashing annual maintenance costs by 45%.
Environmental Compliance:
The meticulously engineered closed box, boasting an impressively low leakage rate of <3mg/m³, harmoniously collaborates with the highly efficient wet dust collector, which features an air volume capacity of 6000m³/h. Together, they achieve an outstandingly low dust emission concentration of less than 5mg/m³, ensuring an exceptionally clean and environmentally friendly operation.
Revolutionizing sustainability, our advanced cooling water circulation system masterfully maximizes efficiency by achieving a remarkable wastewater reuse rate exceeding 95%. This innovative system not only conserves water but also contributes significantly to an eco-conscious and sustainable production process.
