Background
The traditional vault hot blast stove wall body is provided with a vault, the vault presses the wall body through the arch foot brick, so that the vault is stable and is not easy to deform and collapse, but after a flat top is adopted, the pressure of the vault is not available, the straight wall is in relative weakness, and after a long time, the furnace wall is easy to crack, fault, skew and other defects due to expansion with heat and contraction with cold, hot air is blown and brushed, so that the service life of the wall body is influenced, and the wall body is possibly collapsed when serious, so that the research of a new hot blast stove wall body structure is of great significance in solving the problems.
Disclosure of Invention
In order to overcome the defects, the utility model provides a hot blast stove wall structure, which solves the problem that the service life of a wall is influenced due to weakening of the wall caused by decompression.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a hot-blast furnace wall body structure, includes the hot-blast furnace wall body, the top of hot-blast furnace wall body is equipped with frame shape reinforcement assembly, frame shape reinforcement assembly includes two vertical girder steel and two horizontal girder steel, and two vertical girder steel are laid along the longeron of hot-blast furnace wall body top and are installed, and two horizontal girder steel are laid along the crossbeam of hot-blast furnace wall body top and are installed, and two vertical girder steel and two horizontal girder steel equipment are around forming fretwork frame body structure.
As a further aspect of the utility model: the longitudinal steel beam is welded and connected with the upper part of the hot blast stove wall body through a cushion block.
As a further aspect of the utility model: and the two end surfaces of the transverse steel beam and the joint of the longitudinal steel beam are respectively provided with a radiating hole, and the diameter of each radiating hole is 60mm.
Compared with the prior art, the utility model has the beneficial effects that:
this hot-blast furnace wall body structure through setting up the frame and consolidates the subassembly, and two vertical girder steel and two horizontal girder steel are laid respectively on the crossbeam and the longeron of hot-blast furnace wall body to two vertical girder steel and horizontal girder steel surround and form a framework structure, make it can increase the intensity of hot-blast furnace wall body, make the resistant firebrick straight wall pressure of hot-blast furnace wall body increase, thereby make the stability of hot-blast furnace wall body strengthen greatly, life has the improvement by a wide margin, avoided the hot-blast furnace wall body to lead to the problem of cracking, deformation, fault and collapse even because of the decompression attenuation.
According to the hot-blast stove wall structure, the cushion blocks are arranged, and the longitudinal steel beams are connected with the steel frame I-beams of the top of the hot-blast stove wall through spot welding of the cushion blocks, so that the pressure of a vault can be increased, and the good stability of the hot-blast stove wall is ensured.
This hot-blast furnace wall structure through setting up the louvre, and the louvre can be under the circumstances that horizontal girder steel is heated, ensures the circulation of air, and then makes horizontal girder steel and vertical girder steel can reduce the problem that produces the deformation because of overheated, has ensured the intensity of horizontal girder steel and vertical girder steel.

Description of the embodiments
The technical scheme of the patent is further described in detail below with reference to the specific embodiments.
As shown in fig. 1-4, the utility model provides the technical scheme that: the hot-blast stove wall structure comprises a hot-blast stove wall body 1, a frame-shaped reinforcing component 3 is arranged above the hot-blast stove wall body 1, the frame-shaped reinforcing component 3 comprises two longitudinal steel beams 32 and two transverse steel beams 31, radiating holes are formed in the joint of the two end faces of the transverse steel beams 31 and the longitudinal steel beams 32, the diameter of each radiating hole is 60mm, the radiating holes can ensure air circulation under the condition that the transverse steel beams 31 are heated, and further the problem that the transverse steel beams 31 and the longitudinal steel beams 32 deform due to overheating can be reduced, and the strength of the transverse steel beams 31 and the longitudinal steel beams 32 is ensured;
the longitudinal steel beam 32 is welded and connected with the upper part of the hot blast stove wall body 1 through the cushion block 2, and the longitudinal steel beam 32 is connected with the steel I-beam of the top steel frame of the hot blast stove wall body 1 through the cushion block 2 in a spot welding mode, so that the pressure of a vault can be increased, and the good stability of the hot blast stove wall body 1 is ensured;
two vertical girder steel 32 are laid along the longeron of hot-blast furnace wall body 1 top and are installed, two horizontal girder steel 31 are laid along the crossbeam of hot-blast furnace wall body 1 top and are installed, and two vertical girder steel 32 and two horizontal girder steel 31 equipment are around forming fretwork frame body structure, two vertical girder steel 32 and horizontal girder steel 31 are around forming a frame body structure, make it can increase the intensity of hot-blast furnace wall body 1, make the resistant firebrick straight wall pressure of hot-blast furnace wall body 1 increase, thereby make the stability of hot-blast furnace wall body 1 strengthen greatly, life has the improvement by a wide margin, the hot-blast furnace wall body 1 is avoided because the decompression attenuation leads to the problem of cracking, deformation, fault collapse even.
