With using Kissinger equation in research field of mold powder
the activation energy for the crystallization of glassy state fluoride free titanium bearing mold powder in heating process (heating rate 5 〜30 K/min) and that for the crystallization of liquid state mold flux in cooling process (cooling rate 5 〜30 K/min) have been studied. Experimental results show that the activation energy E for the crystallization of glassy state flux in heating process is about 52. 75 kJ/mol and the E for the crystallization of liquid state flux in cooling process is about 61. 15 kJ/mol. The peak temperature of crystallization of test glass flux is 915 〜940 K
the glassy state flux film formed in quick cooling process has recrystallization behavior
therefore it should consider both liquid state flux crystallization behavior in cooling process and recrystallization behavior in flux film in mold.
