The 95% alumina heat storage ball from Zibo Win-Ceramic Material Co. Ltd is a spherical refractory ceramic designed for high-temperature thermal energy storage in industrial applications. Each ball measures 13mm in diameter and is composed of aluminum oxide (Al2O3) at 95% purity, offering high thermal shock stability, heat retention capacity, and resistance to oxidation and slag. These properties make it ideal for use in steel reheating furnaces, power plants, and petrochemical crackers, where rapid heat exchange and durability are critical.
The heat storage balls function by dividing airflow into small streams, creating turbulent flow that enhances heat transfer efficiency. With a typical thermal conductivity of 20-30 W/m·K for 95% alumina, the balls can achieve temperature efficiencies of 90% or higher, preheating gases to within 100°C of flue gas temperatures. The compact size and high circulation capacity of the ball bed ensure consistent performance, even with ash accumulation. Standard industry specifications for such ceramics include a bulk density of 2.8-3.2 g/cm³, a compressive strength of 800-1200 MPa, and a maximum operating temperature of 1700°C.
These heat storage balls are widely used as fillers in regenerators for air storage equipment, steel furnaces, and blast furnace gas heating systems. Their reusability and ease of cleaning reduce maintenance costs, while their resistance to thermal cycling extends service life. Packaging is typically in double-layer polyethylene woven bags with a net weight of 25kg per bag, plus palletisation for safe international transit. Buyers should confirm packaging and handling requirements to minimise breakage during shipping.

Before ordering, verify the alumina content and purity of the heat storage balls, as this directly impacts their thermal conductivity and durability. Confirm the diameter and tolerance specifications to ensure compatibility with your furnace’s regenerator design. Request material test reports (MTRs) for thermal conductivity, compressive strength, and bulk density to validate performance claims.
Logistics for heat storage balls typically involve sea freight in 25kg bags palletised for stability. Confirm the Incoterms (e.g., FOB Qingdao) with the supplier, as this determines responsibility for shipping costs and insurance. Lead times may vary based on order volume, with standard production runs taking 4-8 weeks. Payment terms often include a 30% deposit, with the balance due prior to shipment.
Quality checks should focus on dimensional accuracy, surface finish, and mechanical integrity. Inspect a sample batch for cracks, chips, or irregularities that could affect performance. Request a certificate of analysis for alumina content and a bulk density test report. For high-temperature applications, confirm the supplier’s testing data for thermal shock resistance and maximum operating temperature. Documentation to secure includes certificates of origin, packing lists, and compliance with industry standards.
