Product Description
The water-cooled boiling cooling bed emerges as the indispensable choice for efficient sand cooling in the realms of investment casting and disappearing mold casting. This advanced apparatus boasts densely packed cooling water pipes, facilitating rapid heat exchange. Despite its intricate design and high energy demands, the system excels in delivering exceptional cooling effects, aligning seamlessly with casting process requirements.
In the specialized domain of precision casting, comprising investment casting and lost foam casting, the cooling efficiency and uniform temperature distribution of molding sand are crucial for achieving superior surface quality and exact dimensional precision in castings. The water-cooled boiling cooling bed has reigned supreme as the pivotal component within high-precision casting sand processing systems, courtesy of its innovative heat exchange structure and meticulous temperature regulation. This article delves into the myriad ways this equipment captivates the market, despite facing challenges related to its complex architecture and energy intensity. It explores dimensions such as thermodynamic optimization, the equipment's adaptability to precision casting, pathways to enhance energy efficiency, and its extensive industrial applications.
1. Technical Principles and Adaptability to Precision Casting
Addressing the unique process characteristics 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 a technological leap through its boiling heat exchange and gradient cooling techniques:
Multi-layer Water-Cooled Pipe Array Design:
Featuring a dense arrangement of stainless steel cooling pipes (Φ25×2mm, spaced 40mm apart) with internal circulating cooling water (flow rate 5-15m³/h), the pipes exhibit a thermal conductivity of 16W/(m·K), outperforming ordinary carbon steel pipes by 60% in heat exchange efficiency.
The pipes are intriguingly stacked at a 15° angle, prompting the sand flow to engage in a vortex-like motion under gravitational influence (flow rate 0.3-0.8m/s). This increases the contact area between sand particles and cooling pipes threefold, elevating the cooling efficiency to 1.5-4.0t/(h·m³).
Precise Adaptation of Sand Particle Size:
Equipped with an adjustable grid (aperture Φ3-Φ8mm), the fluidized bed ensures only qualified sand particles (AFS 50-120) proceed to the cooling zone, while oversized or undersized particles are redirected to the regeneration system. This maintains an impressive sand temperature uniformity compliance rate of over 98% (±3ºC).
For EPS beads employed in lost foam casting, an electrostatic separation module (voltage 30kV) is integrated to efficiently isolate residual foam particles (removal rate >95%), preventing cooling pipe blockages.
2. Core Advantages and Process Value
Despite the inherent challenges of a complex structure and elevated energy consumption, this equipment distinguishes itself with remarkable process adaptability optimization and comprehensive life cycle cost management:
Industry-Leading Cooling Efficiency:
Achieve a 35% reduction in energy use compared to traditional vibrating cooling beds (energy consumption per ton of sand ≤18kW·h), and a remarkable 80% water savings relative to pneumatic cooling systems.
With sand particle moisture content consistently maintained at 2.0-2.5%, the uniformity surpasses natural cooling by 50%, while the shrinkage defect rate of castings plummets to below 0.3%.
High Temperature Resistant and Long-Lasting Design:
Constructed from Incoloy 825 nickel-based alloy, the cooling tubes withstand temperatures up to 1200ºC. The surface is fortified with a 50μm thick plasma-sprayed Al2O3 coating, ensuring a robust service life exceeding 8 years.
Thanks to the modular tube array structure, individual tube replacements are swift, reducing maintenance times to under 30 minutes, while slashing annual maintenance costs by 45%.
Environmental Compliance:
Delight in our advanced system where a sealed enclosure (boasting an impressive leakage rate of less than 3mg/m³) pairs seamlessly with a high-efficiency wet dust collector (capable of handling an air volume of 6000m³/h). Together, they ensure that dust emission concentration is maintained at an exceptionally low level of less than 5mg/m³.
Experience the pinnacle of sustainability with our state-of-the-art cooling water circulation system, engineered to perfection. This system achieves a remarkable wastewater reuse rate exceeding 95%, demonstrating our commitment to environmental responsibility and resource conservation.
