Embodiment 1

[0034] A kind of false corbel bracket built in Y shape

[0035] See now figure 1 , figure 1 It is a schematic diagram of the structure of the artificial corbel bracket according to the embodiment of the present invention. As shown in the figure, the load-bearing beam 1 is a horizontally arranged steel beam with a length of 935mm. The upper part of one end is provided with a screw hole for bolting with the angle steel 5, and the lower part of one end is fixedly welded to a stiffened plate with a screw hole. , The lower part of the other end is also fixedly welded to a stiffened plate with screw holes;

[0036] The supporting member 2 has a length of 810mm, both ends of which are provided with screw holes, one end is bolted to the stiffened plate of the load-bearing beam 1, and the other end is provided with screw holes;

[0037] The length of the chute contact piece 3 is 894mm, one end is provided with a screw hole for bolting to the load-bearing beam 1, and the lower part of the oth...

Embodiment 2

[0039] A kind of false corbel bracket built in V shape

[0040] This embodiment is the same as the embodiment 1 except that the false corbel bracket is constructed under the load-bearing beam 1 by the supporting member 2 and the chute contact member 3 in a V shape.

Embodiment 3

[0042] A method for using a fake corbel bracket in the overhaul of corbel bricks for CDQ chute is characterized by comprising the following steps:

[0043] a, prefabricated false corbel bracket parts

[0044] According to the structural characteristics of the CDQ chute, the force analysis is carried out to determine that the bracket meets the actual force requirements, calculate the size of the bracket, prefabricated fake corbel bracket parts, manufactured fake corbel bracket and CDQ corbel quantity, The external dimensions are the same; the false corbel bracket parts include load-bearing beam 1, support 2 and chute contact 3.

[0045] b. Assemble the false corbel bracket into a single whole in the furnace

[0046] The false corbel bracket parts including the load-bearing beam 1, the support member 2 and the chute mouth contact member 3 are transported into the furnace in single pieces from the furnace mouth, and assembled into a single body of the false corbel bracket in the furnace;...

Abstract

The invention relates to a false corbel bracket. The false corbel bracket comprises a bearing beam (1), a support member (2) and a chute opening contact member (3). The corbel bracket is characterized in that the bearing beam (1) is a steel beam horizontally arranged, screw holes are respectively formed in both ends of the support member (2), and a screw hole is formed in one end of the chute opening contact member (3), so that the chute opening contact member (3) is in bolt connection with the bearing beam (1) through a bolt; a stiffened plate with a screw hole is fixedly welded to the lower part of the other end of the chute opening contact member (3), so that the chute opening contact member (3) is in bolt connection with the support member (2) through a bolt; a screw hole is formed in the other end part of the chute opening contact member (3), so that the chute opening contact member (3) is in bolt connection with angle steel (5) through bolts; therefore, the false corbel bracket is formed through overlapping of the support member (2) and the chute opening contact member (3) below the bearing beam (1) in a Y shape. The false corbel bracket and the using method thereof during examining and repairing corbel bricks in a dry quenching chute, disclosed by the invention, have the advantages that the false corbel bracket is simple in structure, is convenient to manufacture, and the bricks on a corbel are supported to ensure that the bricks do not collapse and to ensure that in a replacing process of the corbel bricks, the structure of fireproof materials of a furnace body is not damaged.

Description

Technical field [0001] The invention relates to a bracket, in particular to a method for using the bracket as a false corbel bracket and its use in the overhaul of the corbel brick of a dry quenching chute. Background technique [0002] In order to meet the national energy conservation and environmental protection requirements, most domestic steel mills and coking plants have built dry quenching instead of wet quenching. According to our domestic dry quenching and structural design, the oblique air duct position is the key. On the one hand, the oblique air duct support bricks have to bear the weight of the upper partition wall and the refractory material inside the ring duct (about 200t). In the body deviation, the oblique air duct support bricks bear weight deviation, and the force is uneven; on the other hand, the refractory working environment of the oblique air duct is harsh, long-term subject to temperature fusion, rapid cold and rapid heat, strong air erosion, coke friction...
