The invention discloses a treatment technology of an anti-ash-deposition and anti-wear alloy material of a waste heat recovery pipeline.An alloy blank is selected, vacuum arc remelting or electro slag remelting is adopted, the smelting temperature ranges from 3,050 DEG C to 3,100 DGE C, the alloy blank is prepared from, by mass, 11.3%-14.4% of Al, 14.6%-17.5% of Mg, 1.25%-1.5% of Fe, 0.40%-0.7% of Si, 0.01%-0.10% of Cu, 1.5%-1.7% of Mn, 1.4%-2.0% of Zn, 0.10%-0.25% of Zr, 1.10%-3.12% of rare earth elements, smaller than 0.015% of impurity content and the balance Ti; the rare earth elements comprise, by weight, 15%-18% of Gd, 3%-5% of Pr, 7%-9% of Dy, 12.5%-12.8% of Ac, 15%-20% of Nd, 11%-13% of Sm and the balance La.According to the treatment technology of the anti-ash-deposition and anti-wear alloy material of the waste heat recovery pipeline, wear resistance and corrosion resistance of tubing can be greatly improved, the tubing adapts to the severe environment, the service life of the tubing is prolonged, a large amount of ash deposits is prevented from splashing, a large number of resources are saved, and the cost is reduced.
