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．
The WCT-2 microcomputer differential thermal balance was used to study the influence of the chemical composition and cooling rate of the flux on its crystallization temperature. The results show that: (1) Under the experimental conditions, the alkalinity increases and the crystallization temperature of the mold flux first increases and then decreases; (2) The F- content increases and the crystallization temperature of the mold flux increases; (3) , The content of MgO increases and the crystallization temperature of mold flux decreases. (4) The crystallization temperature of mold flux decreases slightly with the increase of cooling rate.
