Slide gate plates are key functional refractories installed in the ladle or tundish slide gate system to control steel flow during casting. As flow-control components, they are subjected to extreme thermal, chemical, and mechanical stresses: high steel temperatures, erosive flow, oxidation, slag attack, mechanical abrasion, and frequent opening/closing cycles. Their lifespan directly affects casting sequence length, ladle turnaround time, production cost, and operational safety.
