Abstract

A manufacturing technology of a girder for thermal power plant building comprises the sequential steps of plate cutting, welding, straightening and polishing and paint spraying. According to the platecutting step, a metal plate is placed on a cutting unit to be cut, so that a plate-shaped part is obtained, and chips are recycled during cutting. According to the welding step, the plate-shaped parts are welded, so that a girder blank is obtained. According to the correcting step, mechanical straightening or flame straightening is conducted on the girder blank, so that a straightened piece is obtained. According to the polishing and paint spraying step, polishing and paint spraying operation are sequentially conducted on the straightened piece, so that the product is obtained. The manufacturing technology of the girder for thermal power plant building is high in adjustability, low in use and maintenance difficulty, good in chip collecting effect and beneficial for the improvement of manufacturing efficiency.

Description

technical field [0001] The invention relates to a production process of a beam used in power plant construction, in particular to a production process of a large beam used in thermal power plant construction. Background technique [0002] Existing thermal power plants need to use a large number of steel structures, such as tower crane shells, power boiler brackets, pipe trusses, etc. Among them, H-shaped and Tian-shaped beams are the most common. In the process of manufacturing these beams In the process, it is necessary to perform blanking, shearing, small plate drilling, welding, straightening, grinding or painting on the original plate. Among them, the plate must be cut during blanking and shearing. [0003] In the prior art, when cutting plates, cutting operations are required, and the cutting methods generally include CNC plasma cutting, CNC flame cutting, CNC water pressure cutting, and CNC aurora cutting. When cutting, the metal sheet to be processed needs to be plac...
