“…Galinari and Dutra [13] studied Sialon-reinforced Al 2 O 3 -C refractories and found that Sialon increased the strength of the materials from 110 MPa to 380 MPa and drastically improved their abrasion and thermal shock resistances. The authors' previous research [14,15] indicated that plate-shaped β-Sialon formed in situ could also significantly enhance both the hot strength and thermal shock resistance of Al 2 O 3 -C refractories.…”

The possibility to reduce clogging in the submerged entry nozzle (SEN) during continuous casting of Ce alloyed stainless steels has been studied. This was done by implementing a new plasma coating material, consisting of yttria-stabilised zirconia (YSZ). The coating was first tested in pilot-plant trials; where the amount of steel teemed through the plasma-coated nozzles was monitored. Thereafter, samples of the coatings from the nozzles were studied using a FEG-SEM equipped with EDS. In addition, the coating material was tested in industrial trials where the performance was judged with respect to the clogging tendency detected as the movement of the stopper rod. The results from both the pilot-plant trials and industrial trials showed that the use of an YSZ coating led to a decreased clogging tendency during the casting in comparison to when using an uncoated SEN. Specifically, the pilot-plant trials showed that the clogging factor was lowered when implementing the YSZ coatings. Furthermore, the industrial trials showed that the clogging tendency, measured by the stopper rod movements, were lower when implementing the YSZ coating.
