The present invention discloses a method for making wear-resistant composite tubes in a cast iron/carbon steel honeycomb sandwich structure. Various wear-resistant metal composite tubes used for delivering powder material or fluid can be produced with the method. The present invention adopts the technical proposal that a three-layer composite tube blank of which the inner layer and the outer layer are carbon steel and the middle layer is high chromium cast iron is cast according to the ingredient and size requirements of the inner and the outer layers of a finished product; the tube blank is deformed by hot rolling, the middle layer is partially broken to form a honeycomb or mosaic structure, the middle layer is inlaid and combined with the inner and the outer layers, and different sizes of composite tube products are obtained; thin walled tubes need to be continuously deformed by cold rolling. The composite tubes have high bonding strength between all layers, and nonuniform boundary texture phenomena are eliminated by an annealing technique. The middle high chromium cast iron layer of the composite tubes is combined with the two layers of carbon steel in a honeycomb or mosaic mode, so the composite tubes have high strength and ductility. The method has the advantages of short technical process, simple operation, no requirement for transforming large equipment and high feasibility.
