Steel structure production line
Steel materials - materials correction- lofting correction (automatic cutting or shearing) - group (Group molding machine), welding (automatic submerged arc welding machine, electroslag welding etc.) - component correction (straightening machine, flame correction) - Drill hole (NC drill or vertical drilling machine, magnetic drill etc.) -wholely assembly (General Assembly manual electric arc welding) - derusting(sandblasting, Shotblast derusting) -painting - marking the number -finished products
1 according to the construction details and the actual size of the steel, plate and profile blanking layout
2, material (should pay attention to control the deformation of the plate, you can choose flame straightening)
3 according to the original design instructions and construction details, make the steel pairs
4 before welding detection (with special attention on the surface to the steel column shoulder beam size not column is positive, otherwise very difficult to adjust the crane Liang Biaogao)
5 welding according to drawing requirements and inspection according to requirements. (after welding, some parts need to be deformed and straightened up)
Welding between 6 connecting plates (a piece of sheet to be removed should be numbered to indicate that it is not to be used because of the mess on the installation site), 7 whole sand blasting (or manual derusting) and paint brushing
8 before leaving the factory, make sure the marking and component number are specified
