Embodiment Construction
[0022] In order to better understand the present invention, the technical solutions of the present invention will be further described below in conjunction with implementation examples and accompanying drawings. Among them, such as figure 1 As shown, the outer side of the coke oven head 7 is provided with a protective plate 5 . A furnace pillar 4 is arranged on the outer side of the protective plate 5 . After the furnace column 4 moves to the outside for a certain distance, the protective plate 5 and the furnace column 4 are spaced apart. Such as image 3 As shown, when the furnace pillar 4 moved to the normal position inwardly, the furnace pillar 4 withstood the protective plate 5, and the protective plate 5 was close to the refractory brick on the burner head 7 of the coke oven. The upper part of the furnace column 4 is provided with an upper horizontal bracing bar 3 , and the lower part of the furnace column 4 is provided with a lower part bracing bar 6 . As in the prio...

The invention provides a local-slippage construction method of a furnace column. The local-slippage construction method of the furnace column comprises the following steps of: moving the furnace column towards the outer side; supporting a heightening column at the upper end of the furnace column for installing a coke oven shed, wherein an end enclosure plate is welded at each of the upper end head of the furnace column and the lower end head of the heightening column, respectively, the two end enclosure plates are superposed together and long slide slots of the same size are arranged on a plurality of corresponding positions on the two end enclosure plates, and bolts penetrate through the slide slots for locking and fixing; dismounting protective plates and modifying the inner part of the coke oven; mounting the protective plates; loosening the bolts penetrating through the slide slots, moving the furnace column towards the inner side, so that the furnace column is resisted against the protective plate, and applying force towards the outer side at the bottom end of the heightening column for enabling the heightening column to be erected. The local-slippage construction method of the furnace column can be used for preventing the coke oven shed from being dismounted repeatedly and can be used for completing some process of dismounting the protective iron pieces before normal construction, so that the working period is saved and the cost is lowered.
Description
technical field [0001] The invention relates to a local sliding construction method of a furnace pillar, in particular to a method for installing a protective plate for a coke oven and a furnace pillar. Background technique [0002] The installation of iron parts for coke oven protection is an important step in coke oven installation. The iron parts for coke oven protection mainly include four parts: protection plate, furnace column, furnace door frame and furnace door. The traditional installation sequence for installing the iron parts of the coke oven guard is to make the protective plate directly contact with the refractory brick masonry of the coke oven head, the masonry column supports the protective plate, and the two side-by-side furnace columns are installed Furnace door frame, finally install the furnace door on the furnace door frame. In the renovation project of the old coke oven, it is necessary to build a coke oven shed on the coke oven first to protect the ra...
