Problems solved by technology
Aiming at the corrosion problem, the traditional method is to thermally spray and surfacing nickel-based alloy materials with high temperature resistance and corrosion resistance on the superheater pipe wall, but the thermal spraying and surfacing technology is expensive and the effect is not ideal. The material is seriously damaged and the construction efficiency is extremely low, which makes it difficult to meet the requirements of mass production

Embodiment
[0029] Embodiment: A kind of superheater anti-corrosion pipe fitting manufacturing process (see attached figure 1 ), including the following steps:
[0030] a. Inspection of the base material of the pipe fittings. Check that the size and material of the base material of the pipe fittings must be consistent with the drawings, and the base material of the pipe fittings is required to be free of damage and trachoma defects;
[0031] b. The surface of the base material of the pipe fittings is polished to remove all kinds of dirt on the surface of the base material of the pipe fittings, so that the surface of the base material of the pipe fittings shows a uniform metallic luster;
[0032] c. Scribe the base material of the pipe fittings, draw out the anti-corrosion area of the base material of the pipe fittings, and reserve non-corrosion-resistant areas at both ends of the base material of the pipe fittings;
[0033] d. Laser cladding, the alloy powder is clad to the corrosion-r...

The invention discloses a manufacturing process and device for an anti-corrosion pipefitting of a superheater and aims to overcome the defect that the construction efficiency of an alloy protecting layer on the surface of a pipefitting is low. Through process steps of pipefitting substrate examination, pipefitting substrate surface polishing, pipefitting substrate lineating, laser cladding and detection successively, strict processing and manufacturing and examining flows are formulated by means of a laser cladding technique. In the laser cladding operating process, a pipefitting substrate isnot damaged, so that the anti-corrosion pipefitting is obvious in anti-corrosion, wear-resistant and high-temperature-resistant effects while being high in construction efficiency and low in cost.
Description
technical field [0001] The invention relates to a superheater, more specifically, it relates to a manufacturing process and device for anti-corrosion pipe fittings of a superheater. Background technique [0002] Garbage incineration is an effective way to deal with domestic garbage at present, and it has the characteristics of volume reduction, harmlessness and resource utilization. However, the corrosion of the heating surface during the waste incineration process is quite serious, which greatly reduces the service life of the heating surface, and the frequent replacement of the heating surface has caused troubles to the safe operation of the waste incinerator. The superheater is a part in the boiler that further heats the steam from the saturated temperature to the superheated temperature, and is an important equipment to ensure the boiler efficiency and steam parameters. The superheater is installed in the flue, which is scoured and corroded by the flue gas horizontally ...
