Investigation of Nanoparticles of Carbon and Calcined Alumina on Mechanical and Corrosion Properties in MgO-C Refractories

Abstract:

Today due to the unique properties of magnesia carbon refractories, the iron and steel industries are of special interest. Therefore, it is important to extend the life of the refractory. The effect of calcined alumina and nanocarbon on the mechanical strength and corrosion resistance against slag refractories magnesia carbon has been studied. Mechanical strength of cold crushing strength (CCS) was measured according to ASTM C0133-97R03 numbers. The bulk density (BD) and apparent porosity (AP) were determined respectively, relative to the size and weight measured using Archimedes method according to ASTM C0020-00R05 numbers and corrosion resistance against slag shrub procedure. Samples prepared at cylinder 50×50 mm were tempered on 250 °C for three hours. The corrosion resistance of the samples cocked on 1350 °C for two hours under reducing atmosphere (coke bed) was evaluated. During the review process of characterization methods, XRD, SEM-EDX has been used. The results showed that the properties improved.
