Treatment technology of anti-ash-deposition and anti-wear alloy material of waste heat recovery pipeline

Abstract

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.

Description

technical field [0001] The invention relates to a treatment process of a waste heat recovery pipeline alloy material which is resistant to dust accumulation and abrasion. Background technique [0002] At present, pipes in the market are commonly used heat-conducting components in the field of industrial equipment, and are widely used in various equipment. According to different application occasions, pipes should have long life, high precision, high rigidity, low noise, high wear resistance and other characteristics. Pipes are widely used in pipes, but due to the harsh working environment of pipes, a large amount of dust accumulates and wears pipes at high speed during work, which seriously affects the service life of pipes, and a large amount of dust splashes out of the main body through the gap, wasting a lot of dust. It causes increased production costs, affects the normal length of the pipe, increases the failure rate, and reduces the work efficiency of the pipe. This pr...
