The Effect of Surfactant Agents on the Oxidation and Slag Corrosion Resistances of the Self-Flowing Refractory Castables in BF Troughs

In this research، the effect of surfactant agents such as; polyoxy ethylene cethyl ether (POECE) and sodium naphthalene solfonate formaldehyde condensation (SNSFC) on the properties of self-flowing ultra-low cement refractory castables in Al2O3-SiC-C system is investigated. For this reason، properties such as; oxidation and slag corrosion resistance are studied. The results are shown that SNSFC has greater effect on the increasing of oxidation and slag corrosion resistances in comparison with another additive. Microstructural investigations are showed that better distribution of SiC particles in the microstructure due to SNSFC can led to improvement of castable properties.
