Problems solved by technology
According to the traditional construction method, the coke is discharged to the lower part of the corbel bricks, and the inner ring brick ceiling device is installed. The corbel bricks are constructed first, and the coke is discharged after the corbel bricks are completed. The construction period needs 33 days, which cannot meet the production requirements. needs

Embodiment 1
[0024] Below in conjunction with accompanying drawing, the method for simultaneous construction of CDQ coke oven corbel brick and cooling section provided by the application will be further described,
[0025] The construction method of the present application comprises the steps:
[0026] 1. Preliminary preparations: before the start of construction, make the hanging pan in the furnace, that is, the above-mentioned partition board, shoulder beam, furnace roof beam, that is, the above-mentioned top support beam frame and fire channel support beam, and the load-bearing bracket of the middle bolt hole, that is, the above-mentioned and the following The shoulder pole beam and the corbel brick load-bearing beam are the above-mentioned load-bearing beams, and the platform support steel pipes are the above-mentioned support columns.
[0027] 2. After the start of work, discharge the coke to the bottom of the cooling section and assemble the hanging pan in the furnace. After the hang...

The invention discloses a construction method, in particular discloses a construction method for simultaneously replacing corbel bricks and cooling section masonry of a CDQ coke oven, and belongs to the technical field of metallurgical production equipment repair and maintenance technology. A construction method for simultaneous replacement of the dry quenching coke oven corbel bricks and the cooling section masonry is provided, which can effectively shorten the construction period of the dry quenching furnace corbel bricks and the cooling section. The construction method realizes the support of the furnace body above the corbel and the separation of the working interface between the corbel and the cooling section by setting an auxiliary support separation structure at the junction of the cooling section and the corbel in the furnace body, and then in the auxiliary support separation structure The corbel bricks and cooling section masonry are dismantled and rebuilt at the same time above and below respectively to complete the simultaneous replacement of the corbel bricks and cooling section masonry.
Description
technical field [0001] The invention relates to a construction method, in particular to a construction method for simultaneous replacement of coke oven corbel bricks and cooling section masonry, and belongs to the technical field of metallurgical production equipment repair and maintenance technology. Background technique [0002] The first-phase CDQ coke oven of a steel and vanadium company affiliated to a domestic iron and steel group was built in 2010 and has been in continuous production for 8 years. Dry coke quenching is an energy-saving technology widely used abroad at present, and its English name is CDQ. The principle is to use cold inert gas to exchange heat with the red-hot red coke in the CDQ oven, thereby cooling the red coke, and the inert gas that has absorbed the heat of the red coke transfers heat to the CDQ boiler, and the CDQ boiler produces The steam is sent to generate electricity. With the development of society, environmental protection and energy requ...
