自蔓延铝热一离心法生产陶瓷内衬耐磨钢管是逐步发展起来的高科技产品，它是继铸石管，稀土耐磨管之后第3代耐磨管道，是在利用铝热反应基础上形成的。化学反应式：Fe。O3＋ZAI、AI。O。＋ZFe十热其反应过程在高速离心的状态下完成，形成以钢管为外套，内衬氧化铝陶瓷的复合管
Self-propagating aluminum heat a centrifugal production of ceramic lining wear-resistant steel pipe is the progressive development of high-tech products, it is cast stone pipe, rare earth wear-resistant pipe after the third generation of wear-resistant pipe is based on the use of aluminum heat reaction Forming. Chemical reaction: Fe. O3 + ZAI, AI. O. + ZFe Ten hot reaction process in the state of high-speed centrifugation to complete the formation of a steel tube, lined with alumina ceramic composite tube
