摘要 实验研究了结晶器保护渣(%:37CaO、2MgO、40SiO2、5Al2O3、5Na2O、11CaF2)在1 300-1 000℃的结晶过程和性能。结果表明,冷却速率≤2℃/s时,该渣的结晶化率达100%。在冷却速率0.1℃/s时,保护渣首先析出树枝状晶体,然后以片状晶体形态析出,直到结晶终止。通过X-射线衍射分析,得出析出的晶体主要有枪晶石(Ca4Si2O7F2)、镁黄长石(Ca2MgSi2O7)、硅灰石(CaSiO3)及镁铝尖晶石(Al2MgO4)。 Course and performance of crystallization of mold flux 37CAO, 2MgO, 40SiO2, 5Al2O3, 5Na2O, 11CaF2 at 1 300 - 1 000 ℃ have tested and studied. Results showed that as cooling rate was ≤2 ℃/s, crystallization ratio of the flux was 100% ; and as cooling rate was 0. 1 ≤/s, dendritic crystal precipitated at first in flux, then lamellar crystal precipitated to last of crystallization. By X- ray analysis, crystal phases of flux consist of cuspidine Ca4Si2OTF2, akermanite Ca2MgSi2O7, wollastonite CaSiO3 and magnesia alumina spinel Al2MgO4.
