Embodiment Construction
[0034] From Figure 1 to Figure 6 It can be seen that the present invention draws a cross reference line on the bottom of the cabinet, that is, the X-O-Y coordinates, and evenly distributes four medium-width plate welding areas A, B, C, and D in the central large circle, and then sets them close to the medium-width plate ( 1) Circular edge plate I (2) on the periphery of the circumference, circular edge plate II (3) close to the periphery of the edge plate I (3), and circular edge plate (4) close to the periphery of the edge plate II Three major welding areas; then lay the first central positioning plate along the x-axis direction with o as the center, and cut a ￠110mm center hole in the center, then place it in place, and open three ￠80mm central theodolites for erection Lay cross reference plates along the X and Y axes in sequence; lay the entire cabinet bottom middle plate in the order of first laying the X-axis direction plate and then laying the Y-axis direction plate in ...

The invention discloses a construction method for preventing welding deformation of a converter gasholder base plate. The construction method includes the detailed steps that the first step, cross datum lines are lined; the second step, welding areas are set; the third step, centralized positioning plates are laid; the fourth step, cross datum plates are sequentially laid; the fifth step, center plates of the whole bottom of the gasholder are laid; the sixth step, spot welding is carried out while the base plate is laid; the seventh step, side plates are laid; the eighth step, the center plates are welded; the ninth step, the side plates are welded; the tenth step, a welding seam vacuum test is carried out. The construction method can not only solve the quality problem that due to the fact that large-area base plates are installed in a splicing mode, the hunch-up phenomenon happens on the gasholder base plate, but also is safe and reliable in usage, a construction period is saved, construction quality is guaranteed, construction efficiency is improved, and construction cost is saved.
Description
technical field [0001] The invention belongs to a construction method for preventing welding deformation, in particular to a construction method for preventing welding deformation of the bottom plate of a converter gas cabinet. Background technique [0002] In the steelmaking system of the domestic metallurgical industry, when the bottom plate of the gas cabinet is installed and welded, the large-area bottom plate will be assembled, and the bottom plate of the cabinet will be arched, which must be cut and repaired. This construction method is time-consuming and laborious, it is difficult to guarantee the welding quality, and the construction efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a construction method for preventing welding deformation of the bottom plate of the converter gas cabinet, which can not only effectively solve the problem of the quality of the bottom plate of the cabinet due to the large-area asse...
