耐火瓷球耐火球是以工业氧化铝和耐火高岭土为主要原料，经科学配方、成形和高温煅烧制成的。它具有：
1.机械强度高，使用周期长；
2.化学稳定性好，不与物料发生化学反应；
3.耐高温性能好，耐火瓷球最高耐热温度可达到 1900 度。
特别适用于化肥厂高低温变换炉、转化炉、加氢转化器、脱硫槽及甲烷化炉中，起分散气液、并支撑、覆盖和保护催化剂的作用。耐火瓷球也可用于钢铁行业的热风炉和加热变换设备中。
Refractory Ball
Refractory Ball is mainly composed of industrial alumina and kaolin, manufactured through science recipe, molding and high-temperature calcinations. It features:
1. High mechanical strength, long life cycle;
2. Chemically stable, not reacting with the material;
3. Temperature-resistant performance, maximum temperature is allowed to be 1,900 Celsius degree.
Fire refractory ball is especially fit for furnace in fertilizer plant in terms of high & low temperature conversion, hydrogenation conversion equipment, desulfurization and methanation furnace tank. It works with the performance of scattering from the gas & liquid, also supporting, covering and protecting the catalyst. It can also be used for the steel industry in the hot-blast stove and heat conversion device.
