連鑄結晶器保護渣結晶溫度

Crystallization Temperature of Continuous Casting Mold Fluxes

摘要: 實驗采用WCT-2型微機差熱天平,用來研究了保護渣的化學組成和冷卻速率對其結晶溫度的影響.結果表明:(1)在實驗條件下,堿度升高,保護渣的結晶溫度先升高后降低;(2)F-含量增加,保護渣的結晶溫度提高;(3)隨著Na₂O,Al₂O₃,MgO含量的增加,保護渣的結晶溫度下降;(4)保護渣的結晶溫度隨冷卻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.
