连铸结晶器保护渣结晶温度

Crystallization Temperature of Continuous Casting Mold Fluxes

摘要: 实验采用WCT-2型微机差热天平,用来研究了保护渣的化学组成和冷却速率对其结晶温度的影响.结果表明:(1)在实验条件下,碱度升高,保护渣的结晶温度先升高后降低;(2)F-含量增加,保护渣的结晶温度提高;(3)随着Na₂O,Al₂O₃,MgO含量的增加,保护渣的结晶温度下降;(4)保护渣的结晶温度随冷却速率的增加略有下降.

Abstract: The influences of chemical compositions and cooling rate on the crystallization temperature of mold fluxes were studied with WCT-2 DTA. Under the experiment conditions, the crystallization temperature increases with the increase of basicity and then decreases; the crystallization temperature increases with F contend and decreases with the enrichment of Na₂O, Al₂O₃, MgO. Increasing cooling rate, the crystallization temperature is reduced slightly.
