An investigation to the microstructure of worn sample of dry vibratable materials for tundish working lining after using 40 hours shows that the materials changes the properties of slag by the chemical filter, increases the viscosity of slag, forms a dense layer at slag/refactories interface, then blocks the more slag penetrate in it. The complex phase formed at the interface, such as magnesiowusite and complex spinel et al, would absorb in more low-melting point minerals, then degrade its melting point and dissolve into slag, which forms low-melting point silicate phase, penetrates into dry vibratable materials along with Monticellite and Merwinite bonding phase by diffusion.
