Influence of Cooling Rate on Crystallization Properties of Mold Fluxes
-
摘要: 采用 WCT-2型差熱分析天平和LEITZ光學顯微鏡(配有 1350℃高溫熱臺),研究了冷卻速率對連鑄保護渣結晶性能的影響.研究結果表明:隨冷卻速率提高,保護渣的結晶溫度顯著降低,結晶率降低,晶體尺寸減小,晶形也有很大改變.Abstract: The influence of cooling rate on the crystallization properties of mold fluxes was studied by WCT-2 Differential Thermal Analysis(DTA) balance and LEITZ optical microscope equipped with 1350CC heating stage. Increasing cooling rate, the crystallization temperature, crystallization ratio, and the size of crys-tal is reduced, and the morphology of crystal is also changed greatly.
