Abstract：In order to determine the effect of melt superheating and annealing temperature on the magnetic properties of Fe78Si9B13amorphous ribbon, the amorphous ribbon with a width of 142mm and a thickness of 23μm were prepared with the melt-spun method at three different superheating temperatures of 180, 200 and 230℃, respectively.The annealing treatment for the amorphous ribbon was performed in the longitudinal magnetic field environment at five different temperatures from 350 to 370℃, and the magnetic properties of the annealed amorphous ribbon were tested with the silicon steel measuring instrument.The results show that with increasing the melt superheating, the exciting power and core loss of amorphous ribbon tend to decrease.With decreasing the superheating and annealing temperature, the distribution region for the magnetic properties of amorphous ribbon becomes narrow while the magnetic stability of amorphous ribbon increases.It is helpful in obtaining the amorphous ribbon with the optimal magnetic properties to increase appropriately the superheating and heat treatment temperature.
