利用拉温光谱手段研究了常温及高温下氟对保护渣微观结构变化的影响,结果表明,氟是改变保护渣结构形态和调节晶体类型的重要组分,保护渣中特有的二聚体结构是枪晶石的典型特征。对于同一渣样,不同冷却方式获得的晶态、玻璃态,与高温熔融状态下的微观结构是完全不同的,常温玻璃态下仍可能表现出一定的晶体结构,熔融态下也不是完全的无序结构,也表现出一定晶体结构的团簇状形态。
The effect of fluorine on the microstructure of mold powder was studied by means of pull temperature spectroscopy. The results show that fluorine is an important component that can change the structure of mold powder and adjust the crystal type. The unique dimer structure in mold flux is Typical characteristics of the gun spar. For the same slag samples, the crystallinity and glassy state obtained by different cooling methods are totally different from the microstructure under the high temperature melting state, and it may still show some crystal structure in the glassy state at normal temperature and not completely in the molten state Order structure, also showed a certain crystal structure of the cluster-like morphology.
