The
slide gate plate is a critical functional refractory component widely applied in modern steelmaking for the precise control of molten steel flow from the ladle or tundish. It operates in combination with a nozzle system, stopper rod or ladle shroud, and a complete slide gate mechanism. As steelmaking processes become more automated, high-speed, and quality-oriented, the performance of slide gate plates has become indispensable to ensure safe casting, stable flow rate, long service life, and consistent steel quality.
Because
slide gate plates must withstand extremely aggressive conditions—thermal shock, severe abrasion, steel oxidation, chemical corrosion, and mechanical stress—the selection of their materials, design, and manufacturing processes plays a decisive role in casting stability. This article provides a detailed technical overview suitable for metallurgical engineers,
refractory specialists, and casting operators who require a deep understanding of
slide gate plate technology.
