In this paper the transition temperature and viscosity of mould powder with different B2O3,TiO2 and CaF2 had been measured,and the corresponding lnη-1/T curve had been plotted.Viscous flow activation energy had been calculated through fitting method.The effect of CaF2,TiO2 and B2O3 contents on the rheology characteristics of mould powder had been investigated.The reasonable TiO2 and B2O3 contents for appropriate rheological properties of mould powder without fluorine are less than 9% and 7%,respectively.
