Effect of Shear Stress on Viscosity and Crystallization Behavior of CaO-SiO2-Al2O3 Based Mold Fluxes

Abstract:

The effect of shear stress on the viscosity and crystallization behavior of CaO-SiO2-Al2O3 based mold fluxes were investigated, and the structure evolution of molten slag under shear stress were characterized by magic-angle spinning nuclear magnetic resonance technology (MAS-NMR). The results showed that with an increase of shear stress, the shear-thinning behavior of molten slag was found, and the strongest shear-thinning behavior was formed with an addition of 15% Al2O3. Correspondingly, the decrement of Q3(1Al) and Q2(1Al) species in molten slag were the largest from MAS-NMR results. In addition, under agitation, the crystallization fraction of sample increased from 71% to 88%, and the average grain size was reduced 23%. However, the shear stress has no influence on the crystal phase.
