1.Ceramic-line d Abrasion Resistant Bends are produced by self-propagating high-temperature synthesis (SHS) and centrifugal casting technology. The effects of additives such as SiO2, CrO3, Na2B4O7 and ZrO2 on the densification degree, combining strength and the toughness of the ceramic layer were of prime interest. The results show that the densification degree of the ceramic layer can be improved by adding SiO2 and CrO3 in the thermite. This improvement correlated with the reduction of porosity of ceramic layer. The combining strength is increased through the addition of a suitable amount of Na2B4O7. The highest fracture toughness of ceramic layer is obtained at 7 wt.% of ZrO2 in thermite. Ceramic-lined compound steel pipe shows excellent service properties when it is used in tubular billet crystallizer, including the prevention of cracks and flakes.
