陶瓷内衬复合管的制作是基于铝热反应，该管从内到外分别由陶瓷、过渡层和钢三层组成，陶瓷层是在2000℃以上高温形成的致密的钢玉瓷，通过过渡层和钢管形成牢固的冶金结合。氧化铝（钢玉）硬度很高（＞HV1000），在自然界中仅次于金钢石、碳化硼、立方氮化硼和碳化硅而位居第五位，因此，其具有很高的抗煤粉、灰渣的冲击磨损能力，且能进行车削、磨削和焊接等加工，是一种具有综合优异性能的复合管材。
The ceramic lined composite pipe is based on the thermite reaction. The pipe consists of three layers of ceramic, transition layer and steel from inside to outside. The ceramic layer is a dense steel-jadeite ceramic formed at high temperature above 2000 C. It forms a solid metallurgical bond through the transition layer and steel pipe. Alumina (steel jade) has a high hardness (>HV1000), ranking fifth only after diamond, boron carbide, cubic boron nitride and silicon carbide in nature. Therefore, it has a high impact wear resistance to coal powder and ash slag, and can be processed by turning, grinding and welding. It is a comprehensive excellent performance. Composite pipe.
