The vaporization and crystallization of CaF 2 –CaO–Al 2 O 3 slags with different MgO contents for electroslag remelting were investigated by various analytical methods. The results show that the main volatiles from investigated slag with 8.8 mass% MgO content at 1723 K are CaF 2 and AlF 3 and contai...
