Incinerator hopper metal structural part machining process

Abstract

The invention discloses an incinerator hopper metal structural part machining process. The process comprises the following steps that S1, plate cutting is conducted, a steel plate is selected as a machining raw material plate, the thickness of the steel plate is 12-16 mm, cutting treatment is conducted on the steel plate, and the plate is subjected to cutting through mechanical cutting and gas cutting; linear cutting adopts mechanical cutting; a part with the curve and the thick steel plate are cut through gas cutting; dirt and grease on the surface of steel are removed before cutting, and a certain space is reserved below the steel, so that slag can be blown out conveniently; and during gas cutting, a cutting torch moves at a constant speed, during thick plate gas cutting, a cutting nozzle is kept perpendicular to the surface of a workpiece, the cutting nozzle is moved to be switched into normal gas cutting after the whole section is cut through, and the speed is slightly slowed down when gas cutting is about to reach the end point of the part. According to the process, good anti-corrosion treatment can be carried out on the metal structural part, the anti-corrosion performance of the metal structural part can be improved, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the field of incinerator equipment, in particular to a process for processing metal structural parts of an incinerator hopper. Background technique [0002] With the development of society and production, more and more garbage will be produced. At the same time, the continuous strengthening of environmental protection awareness requires people to handle and dispose of garbage more scientifically. Among them, the incineration method will play an increasingly important role. It plays an important role. The garbage incinerator is the main equipment in the incineration method, and the slag well is an indispensable part of the garbage incinerator. The anti-corrosion effect of the metal structural parts of the slag well is poor, which leads to a short service life of the metal structural parts of the slag well; at the same time, in the process of spraying and coating, the spraying effect is uneven and the coating is inconvenient. The...

[0002] With the development of society and production, more and more garbage will be produced. At the same time, the continuous strengthening of environmental protection awareness requires people to handle and dispose of garbage more scientifically. Among them, the incineration method will play an increasingly important role. It plays an important role. The garbage incinerator is the main equipment in the incineration method, and the slag well is an indispensable part of the garbage incinerator. The anti-corrosion effect of the metal structural parts of the slag well is poor, which leads to a short service life of the metal structural parts of the slag well; at the same time, in the process of spraying and coating, the spraying effect is uneven and the coating is inconvenient. Therefore, an incineration It is necessary to process the metal structural parts of the furnace hopper
