Refractory Ladle Slide Gate Plate

The main raw materials of the ladle slide gate are aluminum carbon and aluminum zirconium carbon. The need for special steel makes the development of ladle slide gates diversified. Sliding plate brick has the advantages of high fire resistance, good chemical stability, slag and liquid metal corrosion resistance, good oxidation resistance, and spalling resistance.
