Product Description
The Water-Cooled Boiling Cooling Bed stands as the pinnacle of sand cooling technology in the realms of investment casting and the innovative domain of disappearing mold casting. This remarkable apparatus, though possessing a complex architecture and requiring significant energy, excels in rapid heat exchange via its compact cooling water passageways. Its outstanding cooling performance successfully meets the rigorous demands of the casting process, making it an indispensable tool in the industry.
Within the sophisticated sphere of precision casting, encompassing both investment and lost foam casting, the cooling prowess and temperature homogeneity of molding sand are pivotal. These factors are crucial in dictating the surface finish and dimensional precision of the casting output. The water-cooled boiling cooling bed asserts its prominence as the cornerstone of high-precision casting sand processing solutions, courtesy of its distinctive heat exchange formation and meticulous temperature regulation capabilities. This exploration delves into its market allure, highlighting its exceptional cooling efficacy amidst the intricate structural and energy consumption challenges, viewed through the lenses of thermodynamic enhancement, casting versatility, energy-efficient advancements, and broader industry applications.
1. Technical principles and adaptability to precision casting
In addressing the nuanced process attributes of investment casting (sand grain size AFS 50-100) and lost foam casting (EPS bead dimension 0.3-0.8mm), the water-cooled boiling cooling bed achieves a revolutionary stride through its boiling heat exchange and stratified cooling methodology:
Multi-layer water-cooled pipe array design:
This design features intricately spaced stainless steel cooling conduits (Φ25×2mm, spaced 40mm), channeling internal circulating cooling water (flow rate 5-15m³/h). The pipe wall's thermal conductance is rated at 16W/(m·K), delivering a 60% superior heat exchange efficiency compared to conventional carbon steel pipes.
Ingeniously angling the pipe array at 15°, the sand cascade induces a vortex action under gravitational impetus (flow rate 0.3-0.8m/s), tripling the interaction area between sand particles and cooling pipes, thus elevating the cooling throughput 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 conforming sand particles (AFS 50-120) proceed to the cooling stage, while oversized or undersized grains are redirected to the regeneration phase. The sand temperature uniformity compliance rate surpasses 98%, maintaining a tight variance of ±3ºC.
For EPS beads within the lost foam casting process, an advanced electrostatic separation module (voltage 30kV) efficiently extracts residual foam particles, achieving a removal efficiency exceeding 95%, thus preventing obstruction in the cooling conduits.
2. Core advantages and process value
Despite contending with the intricacy of its construction and substantial energy demands, this equipment showcases unparalleled value through its tailored process adaptability and comprehensive life cycle cost management:
Industry-leading cooling efficiency:
Achieving a 35% reduction in energy usage compared to traditional vibrating cooling beds (consuming ≤18kW·h of energy per ton of sand), alongside an 80% reduction in water usage compared to pneumatic cooling systems;
The sand particles maintain a moisture consistency of 2.0-2.5%, offering a 50% improvement over the uniformity attained through natural cooling methods, thereby minimizing casting shrinkage defects to an impressive rate of below 0.3%.
High temperature resistant and long-lasting design:
Crafted from Incoloy 825 nickel-based alloy, the cooling tubes demonstrate resilience to temperatures as high as 1200ºC and are further fortified with a 50μm thick Al2O3 plasma-sprayed coating, ensuring a service life that exceeds 8 years;
The modular tube array framework allows for the swift replacement of individual tubes, reducing maintenance time to less than 30 minutes and slashing annual maintenance expenses by 45%.
Environmental compliance:
With a closed box design (leakage rate <3mg/m³) harmonizing with a wet dust collector (capacity of 6000m³/h), the system achieves dust emission concentrations below 5mg/m³, setting a benchmark for environmental responsibility;
