Top-combustion type hot-blast stove refractory material sectioned masonry construction method

Abstract

The invention relates to the field of metallurgical engineering construction, in particular to a top-combustion type hot-blast stove refractory material sectioned masonry construction method. The top-combustion type hot-blast stove refractory material sectioned masonry construction method is characterized by comprising the steps that 1, a platform is reasonably designed and erected according to the size of the construction platform needing to be erected on a brick holder and the mass of people, objects and machines on the platform, and it is guaranteed that the platform meets the safety requirements; 2, the construction platform in the step 1 is erected on the brick holder; and 3, refractory material masonry is simultaneously conducted on a regenerative chamber on the lower portion of a furnace body and a pre-combustion chamber above the construction platform. According to the top-combustion type hot-blast stove refractory material sectioned masonry construction method, the construction platform is erected on the brick holder at a hot air outlet, thus refractory material sectioned simultaneous construction on the lower regenerative chamber and the upper pre-combustion chamber is achieved, the construction efficiency is improved while the masonry quality is guaranteed, the construction period is shortened, the construction cost is reduced, and good application prospects are achieved.

Description

technical field [0001] The invention relates to the field of metallurgical engineering construction, in particular to a construction method for segmented masonry of refractory materials for a top-combustion hot blast stove. Background technique [0002] With the continuous progress of blast furnace ironmaking technology, the hot blast stove is developing towards the direction of high efficiency, environmental protection, long life, high blast temperature and compact economy. Compared with the external combustion hot blast stove and the internal combustion hot blast stove, the top combustion hot blast stove has the advantages of small footprint, low steel consumption, and less refractory masonry, which makes it more suitable for the construction of modern hot blast stoves. Top-fired hot blast stoves have greatly increased in the design, selection and usage of hot blast stoves, especially in the renovation project of hot blast stoves. The refractory masonry method of the trad...

AI Technical Summary

Problems solved by technology

The refractory masonry method of traditional top-fired hot blast stoves is to build them section by section from bottom to top or from top to bottom, which has the advantage of good quality of masonry, but it is time-consuming and laborious, which is not conducive to saving the construction period

Especially when the masonry height is high, the required masonry platform is also high, which is not conducive to the safety of construction personnel.
