Alumina-carbon, alumina-zirconia-carbon, magnesia-alumina-spinel slide gates and corundum, alumina-carbon, mullite, magnesia-alumina-spinel upper and down slide nozzles are made of quality materials with phenolic resin binder through pitch impregnation in vacuum and mid temperature treatment. They are classified into high temperature sintered and unburned products. The ladle slide gateshave the good thermal stability, erosion resistance to molten steel, corrosion resistance and long service life. They are widely used in 20-300t steel ladles and various tundishes to well control flow rate of molten steel with safety and easy switch.
