摘　　要：对用于球式热风炉的高铝质、硅质和高密度镁铝质耐火球的理化性能和热工特性进行了研究,对其使用效果进行了分析。结果表明:高密度镁铝质耐火球有利于热风炉蓄热和热传递,同时可解决粘球问题;其在长期高温负荷作用下,能保持结构稳定,不发生脆化和软化。Physicoehemical and thermal properties of high alumina ball, silica ball and high density magnesite-alumina ball applied in pebble stove are studied, and then the application effects are analyzed. Results show that high density magnesite-alumina ball is beneficial to heat retaining and transferring of pebble stove and can solve ball bonding problem. In addition, under high temperature and high load conditions, density magnesite-alumina ball can maintain long-term structural stability without the risk of embrittlement and softening.
