Slide Gate Plate For Tundish
Zirconia ladle slide plates are specifically designed for the sliding nozzle mechanism of ladles and are particularly suitable for difficult-to-cast steel grades such as high-calcium steel, high-manganese steel, and titanium-containing stainless steel. ZrO₂ slide plates demonstrate outstanding performance in resisting calcium erosion from molten steel and preventing rapid enlargement of the nozzle orifice.
Products Description
In the continuous casting process, the slide gate plate for the tundish is one of the core refractory components used to control molten steel flow. As a long-standing supplier to the metallurgical industry, Changtai has continuously optimized material selection and design based on actual operating conditions, and has developed slide gate plates suitable for various types of casting machines.
Key Advantages
Resistant to Hole Expansion
When used with calcium-treated steel, zirconia slide plates maintain relatively intact hole walls, ensuring good roundness of the steel flow and preventing a significant decline in flow control accuracy due to continuous casting. They are particularly suitable for steel grades with strict calcium content requirements, such as automotive sheet steel and pipeline steel.
Thermal Shock Resistance
Leveraging the toughening mechanism of phase transformation, zirconia material is resistant to cracking under rapid cooling and heating conditions. By controlling the content of ZrO₂ crystal stabilizers, Changtai ensures that the slide gate plates can withstand high-temperature erosion while maintaining a certain degree of toughness, thereby reducing the risk of edge chipping and cracking during use.
Minimal Mechanical Wear
The working surfaces of our zirconia Slide Gate Plates undergo precision double-sided grinding, resulting in a low surface roughness. When operating within the slide gate mechanism, the opening force remains stable, with no sticking or jamming, and places no additional strain on the mechanism's springs.
Customization
Changtai can provide different bore diameters (e.g., Φ15mm to Φ30mm) and slide gate plate thicknesses based on the user's ladle mechanism model (such as Floget, Interstop, Vesuvius, etc.) and steel throughput requirements, ensuring optimal compatibility with existing processes.
