Refractory Ladle Monoblock Stopper Rods for Steel Manufacturing Mainly Alumina-Carbon. Stopper Rods are mainly made of alumina-carbon, magnesia-carbon and zirconia-carbon materials, featuring outstanding corrosion resistance, high temperature resistance and excellent sealing performance. Stoppers are installed in ladles and play a vital role in precisely regulating the flow of molten steel during steelmaking. Available in alumina-carbon, magnesia-carbon, zirconia-carbon and magnesia-alumina spinel-carbon grades to best suit your requirements. They offer excellent resistance against erosion and chemical attack from molten steel. Specially designed for argon purging applications, they help remove inclusions, improve steel cleanliness and ensure process integrity in steel production.
