Description

Technical Field

Background Art

[0002] At present, the refining of coke mainly uses coke ovens, which adopt ramming coking process and top-loading coal coking process. The coke oven is mainly composed of a basic platform, a small flue, a regenerator, a ramp, a combustion chamber, and a furnace roof. Among them, the refractory masonry of the combustion chamber occupies an important position in the construction task of the coke oven. The quality of the refractory masonry of the combustion chamber determines the success or failure of the construction of the entire coke oven. Nowadays, with the development of science and technology, the height of the combustion chamber of the coke oven is getting higher and higher, and even has reached 8 meters. When the combustion chamber of the coke oven is built, because the width of the carbonization chamber is very narrow (usually 0.45m~0.6m) and the height is large (usually 6m~8m), the stability and safety of the scaffolding of the standing platform of the furnace builders are difficult to guarantee, which seriously affects the construction safety of the furnace builders and the quality of refractory masonry. The scaffolding commonly used for masonry of the furnace wall of the combustion chamber of the coke oven is cumbersome to erect and dismantle, which increases labor and affects the construction period of the coke oven. Therefore, it is necessary to propose improvements. Utility Model Content
