Corrosion of refractory alumina plates used in the sliding gate system of steelmaking ladle: Chemical experiment

Enhancing the thermal shock and corrosion resistance of low‐carbon Al2O3–C refractories: The role of h‐BN composite powder

“…1,2 Generally, a high graphite content (8-20 wt.%) is necessary to ensure excellent resistance to slag corrosion and thermal shock. [3][4][5] However, high content carbon is easily oxidized deteriorating the thermal shock and slag corrosion resistance of the refractories. 6 Moreover, because carbon in the molten is unsaturated, the carbon would dissolve in the molten steel resulting in contamination.…”
