Need carefully selecting the refractory materials which are appropriate for each respective part.A variety of shaped and unshaped refractory materials for new installations and repairs to Blast Furnaces:
• Silica-Alumina;
• Alumina;
• ASC (Alumina-Silicon Carbide-Carbon);
• Silicon carbide (self-bonding, Silicon Nitride bonding, and Sialon bonding)
• Monolithic Refractories
