1 QC Slide Gate Plate System is designed for precise and reliable control of molten steel flow during steelmaking and continuous casting operations. Installed on steel ladles and related flow-control equipment, the system uses refractory slide gate plates to regulate, reduce, or shut off the flow of molten steel between the ladle, tundish, and casting system.
The slide gate plates are manufactured from carefully selected refractory raw materials, including high-purity alumina, corundum, zirconia-containing materials, magnesia, spinel, and carbon. Different material formulations can be selected according to steel grade, operating temperature, slag composition, casting conditions, and required service life.
Xintai Refractory provides Al-C, Al-Zr-C, Mg-C, and Spinel-C slide gate plate solutions with customized dimensions and material specifications. The plates are designed to maintain mechanical strength and dimensional stability under severe thermal shock, molten steel erosion, and chemical corrosion.
The 1 QC Slide Gate Plate System is suitable for steel plants looking for stable molten steel flow control, dependable refractory performance, and customized slide gate components for different ladle capacities and casting configurations.
