Abstract: aimed at the structure of 2 * 1100MW unit boiler steel laminated beam, through quantitative analysis and calculation of rational and qualitative, provide theoretical support for the laminated beam, and the welding technique and the corresponding technology, to effectively control the deformation of the beam, the deformation control difficult large laminated beam production, ensure that the laminated beam arch degree, laminate, laminated between the perforation rate and other technical indicators meet the design requirements and satisfy the installation performance. In this paper, the deformation control technology of laminated beam production are summarized, and successfully applied to the production of the largest laminated beam, a certain guidance and reference meaning to the similar large steel structure fabrication deformation control. |
