| Abstract: | To control the crystallization properties of mold fluxes,the influence of the Al2O3 content(mass%) on the crystallization properties of mold fluxes was obtained by constructing the CCT and the TTT diagram using SHTT.The results show that with the increase of the Al2O3 content,the critical cooling rate of mold fluxes was decreased that had a negative effect on the crystallization properties of mold fluxes. |
