Product Description
Refractory ceramic ball is high-temperature resistant spherical packing made of bauxite via high-temperature sintering. It is divided into medium-alumina and high-alumina grades, with dual functions of heat storage for industrial kilns and catalyst support for chemical towers. Our products solve the common troubles of low-grade balls cracking, powder falling and frequent shutdown maintenance, matching medium & high temperature working environments.
- Excellent thermal shock resistance: No crack or pulverization under frequent heating & cooling cycles, avoid tower pipeline blockage and abnormal pressure drop.
- High compressive strength: Bear heavy catalyst bed load and long-term kiln impact, greatly reduce replacement frequency.
- Stable chemical inertness: Resist high-temperature flue gas, weak acid & alkali, no impurity precipitation to protect catalysts and kiln lining.
- Outstanding heat storage performance: Fast heat absorption & release, stabilize furnace temperature and cut fuel consumption by 10%-20%.
- Full grade cost matching: Multiple alumina content options to balance procurement cost and service performance for different working conditions.
