Embodiment Construction

[0045] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0046] The CDQ slanted air duct support brick maintenance construction process of the present invention comprises the following steps:

[0047] a) Install the ceiling support device

[0048] see now figure 1 , figure 1 It is a schematic diagram of the ceiling supporting device of the embodiment of the present invention. As shown in the figure, the chain hoist 2, the wire rope 3 and the overhead brick support 8 are used as a ring-shaped spreader to lift the upper masonry of the inclined air duct over the roof brick, and the direction of self-weight of the annular masonry on the upper part of the inclined air duct pillar is applied. On the contrary, the overall lifting prestressing force prevents the upper part of the masonry from sinking when the inclined air duct pillars are disassembled during construction, and the lower part of the roof brick is supporte...

Abstract

The invention discloses a coke dry quenching slope air course supporting brick overhaul construction process, which comprises the following steps: a) mounting a suspended ceiling supporting device; b) removing part of refractory bricks of a pillar of the slope air course; c) mounting an piece for anchoring the root part of the pillar of the oblique air course; d) providing castable and making castable prefabricated bricks; e) constructing the castable and building the castable prefabricated bricks; and f) removing the ceiling supporting device. The coke dry quenching slope air course supporting brick overhaul construction process has the advantages of prolonging the service life of the supporting part of the slope air course, reducing overhaul construction period, reducing maintenance cost and saving production cost.

Description

technical field [0001] The invention belongs to the technical field of maintenance and construction of kilns, and in particular relates to a construction technique for the maintenance of support bricks in a CDQ inclined air duct. Background technique [0002] In order to meet the requirements of national environmental protection, most domestic steel mills and coking plants have successively built large-volume dry coke quenching instead of wet coke quenching. From the structural design point of view of CDQ, the location of the inclined air duct is the key. On the one hand, the supporting bricks of the inclined air duct have to bear the weight of the upper partition wall and the internal refractory material (about 200t) of the surrounding air duct. During the production process, the furnace body is in the middle, The supporting bricks of the inclined air duct bear weight shift and uneven force; on the other hand, the working environment of the refractory material in the inclin...
