Abstract

The invention discloses a sectional assembling and mounting method for a converter vaporization flue, wherein the mounting method comprises the following construction steps: step I, carrying out construction preparation; step II, assembling, wherein a vaporization cooling flue basically enters a site in a sectional mode as a result of a large diameter, an inclined section II and an inclined section II are combined together as well as a corner flue I and a corner flue II are assembled together for reducing safety accidents for working high above the ground under a condition that turning is permitted in a plant structure space; and step III: hoisting, wherein the inclined section assembly is firstly hoisted, and the corner section assembly is hoisted after the inclined section assembly is hoisted. The sectional assembling and mounting method disclosed by the invention has the advantage of saving use of large hoisting equipment, improving efficiency of labor, reducing labor intensity, avoiding or reducing risks caused by working high above the ground, and improving mounting control risks.

Description

technical field [0001] The invention relates to a construction method, more specifically, to a method for segmentally combined installation of a converter vaporization flue. Background technique [0002] The vaporization cooling flue system is an important part of the converter. As the key equipment for the recovery of the converter flue, there are direct hoisting and beam construction methods for its installation. However, considering factors such as the length and weight of the vaporization flue itself, The vaporization flue must be installed in sections. How to ensure the installation quality of the vaporization flue and improve the installation efficiency is the focus of consideration. At present, the existing combined installation method of a converter vaporization flue has not been retrieved in the National Patent Office of China; but there are patent designs with similar names; Construction method of converter gasification flue blowdown system", application number: C...
