Product Description
Water-cooled boiling cooling beds are renowned as the quintessential sand cooling apparatus, extensively utilized in investment casting and disappearing mold casting. With its intricate design and need for precise sand particle sizing, this advanced system excels by rapidly facilitating heat exchange via densely packed cooling pipes. Despite its complexity and elevated energy demands, it consistently delivers superior cooling performance, ensuring the casting process requirements are impeccably met.
In the realm of precision casting, including investment and lost foam casting, the cooling efficiency and even temperature distribution of molding sand are paramount. These factors play a crucial role in defining the surface finish and dimensional precision of castings. The water-cooled boiling cooling bed stands as a pivotal component of high-precision casting sand processing systems, thanks to its distinctive heat exchange mechanism and meticulous temperature regulation capabilities. This comprehensive analysis delves into the equipment's market success achieved through its exceptional cooling prowess, tackling the challenges posed by its complex structure and high energy demands. Explore insights into thermodynamic optimization, precision casting adaptability, energy efficiency enhancements, and broad 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 pioneers a technological leap through advanced boiling heat exchange and gradient cooling techniques:
Multi-layer water-cooled pipe array design:
Featuring a densely packed arrangement of stainless steel cooling pipes (Φ25×2mm, spaced at 40mm), this system circulates cooling water internally (flow rate 5-15m³/h). With a pipe wall thermal conductivity of 16W/(m·K), it is 60% more efficient than standard carbon steel pipes.
The pipe array, inclined at a 15° angle, facilitates a vortex motion of sand flow propelled by gravity (flow rate 0.3-0.8m/s), significantly boosting the contact area between sand particles and cooling pipes by threefold, achieving cooling efficiencies of 1.5-4.0t/(h·m³).
Precise adaptation of sand particle size:
The fluidized bed integrates an adjustable grid (aperture Φ3-Φ8mm) ensuring only sand particles meeting specifications (AFS 50-120) proceed to the cooling zone. Oversized or undersized particles are automatically redirected to the regeneration system, with a remarkable sand temperature uniformity compliance rate of >98% (±3ºC).
For EPS beads used in lost foam casting, an added electrostatic separation module (30kV) efficiently extracts residual foam particles, achieving a removal rate exceeding 95%, thereby preventing cooling pipe blockages.
2. Core advantages and process value
Despite the intricacies of its design and substantial energy usage, this equipment showcases extraordinary value through optimized process adaptability and comprehensive cost management across its lifecycle:
Industry-leading cooling efficiency:
Achieve up to 35% energy savings compared to traditional vibrating cooling beds, with energy consumption per ton of sand maintained at ≤18kW·h. Additionally, this system conserves 80% more water compared to pneumatic cooling solutions.
Sand particle moisture content remains consistently stable at 2.0-2.5%, offering a 50% improvement over natural cooling uniformity, and reducing casting shrinkage defect rates 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. Its surface, fortified with a 50μm Al2O3 coating through plasma spraying, endures over 8 years of service.
The modular tube array allows for single tube replacements, with maintenance times under 30 minutes, leading to a 45% reduction in annual maintenance costs.
Environmental compliance:
Our advanced closed box system, boasting a minuscule leakage rate of less than 3mg/m³, seamlessly integrates with our high-efficiency wet dust collector, which operates at a robust air volume of 6000m³/h. Together, they achieve an impressively low dust emission concentration of under 5mg/m³, ensuring an exceptionally clean environment.
Our state-of-the-art cooling water circulation system is designed to optimize resource efficiency, achieving a remarkable wastewater reuse rate exceeding 95%. This commitment to sustainable practices not only conserves water but also enhances your operational sustainability.
