摘　　要：用石油焦代替重油可以大幅降低玻璃生产成本,但同时也大幅降低了玻璃窑蓄热室格子体用耐火材料的使用寿命。为了提高玻璃窑蓄热室格子体的使用寿命,首先研究了使用石油焦后玻璃窑炉渣的化学组成和碱硫比,蓄热室格子体镁质残砖的损毁机制,以及直接结合镁铬砖、电熔再结合镁铬砖和电熔再结合高纯镁铝尖晶石砖的抗玻璃窑炉渣侵蚀性。在此基础上,采取了一系列针对性的对策,优化了耐火材料的配置,显著提高了格子砖的寿命,满足了玻璃工业发展的需求。Replacing heavy oil with petrol coke can greatly reduce the cost of glass production,but obviously shorten the service life of refractories used in the regenerator checker body of glass tanks.In order to prolong the service life of regenerator checker body,the chemical composition and the alkali-sulfur ratio of glass tank slag after using petrol coke,the damage mechanism of residual magnesia bricks in the regenerator checker body were studied,as well as the corrosion resistance of three magnesia based bricks(direct bonded magnesia chrome bricks,fused rebounded magnesia chrome bricks,and fused rebonded high purity magnesium aluminate spinel bricks).On this basis,a series of targeted countermeasures were adopted to optimize the configuration of refractories,significantly improving the service life of checker bricks and meeting the requirements of glass industry development.
