Construction process for smoke canal swinging assembly of sintering device

Abstract

The invention discloses a sintering machine flue lifting and assembling construction process, which comprises: manufacturing flue lifting segment and flue support according to the design requirement,and mounting the flue support to the mounting position; manufacturing two slideways on the bearing beam or flue support; manufacturing a cantilever platform on one end of the workshop, and disposing aslideway on the cantilever platform, where the slideway has the same specifications with that on the bearing beam or flue support and is connected therewith; lifting the first and the second flue lifting segment onto the cantilever platform by a lifting equipment, moving the flue lifting segments on the slideway by a traction device, and mounting them onto the flue support; assembling the first and the second flue lifting segment to the corresponding position and welding according to the technological requirements. The construction process of the invention is suitable for the lifting and mounting operation in old production line technical reconstruction performed in narrow spaces, has low requirement to mounting site, can shorten lifting and mounting operation period, and can greatly reduce the engineering construction cost.

Description

technical field [0001] The invention relates to the installation and construction technology of the flue (or dust-falling pipe) used in the sintering machine in the ironmaking system of the metallurgical industry, in particular to the construction technology of lifting and transporting the flue of the sintering machine. Background technique [0002] The flue used by the sintering machine in the sintering workshop of the ironmaking system of the iron and steel smelting enterprise is usually relatively large, with a flue diameter of more than three meters or four meters, and a larger one can reach five or six meters, which is mainly determined by its production capacity; The environmentally harmful waste gas and dust-containing flue gas generated in the process are initially dedusted through the flue, and then transported to the dust removal treatment equipment for further treatment, and then discharged into the atmosphere after being harmless. Due to the large diameter and lo...

Problems solved by technology

These two hoisting installation methods, in addition to the long hoisting and installation time and low work efficiency, have higher requirements on the installation site, especially to ensure that the crane can pass through without obstacles and ensure that the crane has a suitable operating space; compared at the installation site Narrow occasions, especially in the occasion of technical transformation of the original production line, and the development of large-scale production equipment, due to the narrow installation space in the building, and some equipment has been placed in place, the crane passage space and crane operation space are limited. Extremely limited, the crane has no minimum operating space, so that the flue cannot be installed in place

At the same time, the production and installation of small segments are adopted according to the design, which also increases the manufacturing cost and installation cost of the flue, especially prolongs the installation period, which is not conducive to the normal production of the manufacturer
