Therefore, choice of refractory materials for steel ladle lining and tundish lining is very crucial to produce clean steel. When the steel melt is re-oxidized by lining refractory materials, the oxygen reacts with dissolved Al (aluminium) in steel to form Al 2 O 3, which partly floats into slag and partly remains in steel as inclusions.
