| Abstract |
| Corrosion of four magnesia based castables with different SiC contents by ladle slag was conducted using the
static crucible test. Effect of SiC content on the slag resistance of castables was investigated by XRD, SEM, EDAX.
The reactions between refractories and slag were simulated through FactSageŽ thermochemical software. It has
been found that SiC can increase the penetration resistance of magnesia based castables, not decreasing their
corrosion resistance. With increasing the content of SiC, the SiO2 content and the viscosity of penetrated slag
increase. The lower wettability of slag to SiC and the higher viscosity of penetrated slag affect the penetration
resistance of magnesia based castables, whereas the reactions between slag and castables affect the corrosion
resistance of magnesia based castables. The thermochemical simulation helps to understand the reaction
mechanism. |
