耐磨复合直管采用离心铸造工艺，弯管采用消失磨真空吸铸工艺，把聚苯乙烯泡沫制作成的模型装入钢管内，在抽真空、热铸状态下，在普通钢管内层复合一层高耐磨合金材料，制成外层为钢管、内层为耐磨材料的复合耐磨管，从而达到韧性与耐磨性的配合。
The wear resistant composite straight pipe is made by centrifugal casting process. The elbow is made by the expendable milling vacuum suction casting process, and the model made of polystyrene foam is loaded into the steel pipe. Under the vacuum and hot casting condition, a high wear-resistant alloy material is made in the common steel pipe inner layer, and the composite wear-resistant pipe with outer layer of steel pipe and inner layer is made of wear-resistant material, so as to achieve the coordination of toughness and wear resistance.
该产品主要具有如下特点：耐磨陶瓷复合管的内衬材质，质量稳定、综合性能好。加入一定量的稀土元素改善钢的合金质量，起细化晶粒作用，在表面形成保护膜；加入一定量Mo使合金在高温下，具有一定抗氧化作用，增加使用寿命；加入一定量的碳化硼，可将硬度控制在HRC45~65的范围之间，同时解决了耐磨钢的硬度和可焊性之间的矛盾，具有较高的耐磨性。
The product mainly has the following characteristics: wear-resistant ceramic composite pipe lining material, stable quality, good comprehensive performance. Adding a certain amount of rare earth elements can improve the alloy quality, refine the grain and form a protective film on the surface; adding a certain amount of Mo can make the alloy have a certain oxidation resistance and increase the service life under high temperature; adding a certain amount of boron carbide can control the hardness within the range of hrc45-65, and solve the contradiction between the hardness and weldability of wear-resistant steel, which has a relatively high value High wear resistance.
