Refractory for continuous casting Tundish is a refractory lined vessel in continuous casting. It contains molten steel with minimum heat losses. Selection of refractory is critical due to longer casting sequence faster tundish turnaround higher campaign life The product range includes low cement castable of different Alumina content (Al 2 O 3 varying from 45 to 90 ) with service range between 1 500 0 C to 1 800 0 C. These are characterized by. Al 2 O 3 content and specific low Fe 2 O 3 and low CaO content. Also water requirement for casting is less than 5 .
