Abstract

The invention discloses a manufacturing and mounting method for an S-shaped bent pipeline of a large sintering flue. The method comprises the following steps that firstly, lofting is conducted on a pipeline model by using design software to obtain space curve parameters, and an actual model of a pipeline body is generated; secondly, an engineering drawing is generated from parts of the actual model of the pipeline body, section view is conducted on the engineering drawing, size parameters of plane placement of a pipeline are obtained, and structural decomposition is conducted on the pipeline according to the size parameters of the plane placement of the pipeline; then, steel plate lofting and composition are conducted according to a decomposed structure, and an actual blanking size is obtained; and finally, according to the actual blanking size, plate rolling is conducted to manufacture the S-shaped bent pipeline, and the manufactured S-shaped bent pipeline is hoisted. According to the method, the model generated through software can be accurate in size, only manufacturing errors exist when the model is in butt joint with field equipment, and finally a low-error assembly finished product is obtained; and the method plays an important role in on-site mounting, accurately displays a weight of a hoisted object as well as a mounting position and angle, and ensures construction safety and construction mounting accuracy.

Description

technical field [0001] The invention belongs to the field of steel structure manufacturing, lofting and installation, and in particular relates to a method for manufacturing and installing an S-curved pipe of a sintered large flue. Background technique [0002] Sintering can be seen everywhere in the factory connected with various large special-shaped flue pipes and special-shaped dust removal pipes. As one of the highlights and characteristics of the entire project, the large flue is an important part of the sintering machine. It connects the sintering main flue and the main electrostatic precipitator, and is arranged symmetrically on both sides. The S-curved flue has the following characteristics and existing problems: [0003] 1. The curved section is a space radius, and it is difficult to confirm the shape and size, which brings great inconvenience to the on-site material lofting; [0004] 2. The diameter of the main pipe of the S-bend flue is large, and the thickness ...
