Self-propagating high-temperature synthesis(SHS) is a new kind of material synthesis technique, and has characteristics with respect to low energy consumption, short synthetizing time, high production quantity, high product purity and no environmental pollution. When SHS combines with centrifugal casting, ceramic-lined compound copper pipe(CLCCP) can be produced, the inner surface of copper pipe can produce ceramic coatings having good wear and corrosion resistance. In order to increase the densification degree, combining strength and toughness of ceramic layer, the effects of additives such as SiO2, CrO3, Na2B4O7 and ZrO2 are researched, adding SiO2 and CrO3 in thermite, the densification degree of ceramic layer increases, adding Na2 B4 O7 in thermite can increase combining strength, adding ZrO2 in thermite can increase the toughness of ceramic layer. CLCCP is used in tubular billet crystallizer, having excellent service effects and decreasing the production cost of tubular billet.
