內(nèi)容簡(jiǎn)介A cerium-carrying solution was developed so as to partially fill the open porosity of Al_2O_3/SiC/C/MgAl_2O_4-based refractory lining microstructure used in Torpedo Ladles, thereby enhancing wear resistance. The protection mechanism was cleared up and introduced from the impregnation technique using a cerium-carrying solution. To that end, scorification trials were conducted, followed by the characterization of refractory microstructure and the use of techniques, such as Scanning Electronic Microscopy (SEM) coupled to Energy Dispersive Spectrometry (EDS), X-ray Diffraction (XRD) and Mercury Porosimetry.
