Alumina Refractory Ball
Refractory Ball, a reliable solution for high-temperature industrial needs, includes specialized variants like high alumina refractory ball and Alumina Ceramic Refractory Ball. Key specs vary by grade: high alumina options have Al₂O₃ content 65%-90% (90% for premium) for strong wear resistance, while Alumina Ceramic Refractory Ball offers ultra-high purity (Al₂O₃ ≥92%) and density. All High-Temperature Refractory Ball variants boast refractoriness 1700-1850℃, cold compressive strength ≥150MPa, and thermal shock stability (10+ cycles of 1100℃ water quenching without cracking).
Ideal for petroleum refining catalytic crackers, metallurgical hot blast stoves, and power plant waste heat boilers, they act as efficient heat-transfer fillers or catalyst supports. Unlike ordinary refractories, they resist erosion and deformation, extending equipment maintenance intervals by 40% and reducing operational costs. For foreign buyers and B-end users, this means long-lasting, low-hassle performance for critical high-heat systems.
