Abstract
Disclosed is a portable cover furnace middle convection plate which includes a bearing plate part and a connecting plate part. The utility model is characterized in that the bearing plate part consists of a plurality of interconnected bearing elements (3) with side blocks (31) arranged at the sides; the connecting plate part consists of the alternatively and adjacently superposed side blocks which are in welding connection with the bearing elements; every two adjacent superposed side blocks are connected by a bolt (5) in between; clearances for match are left between every two adjacent superposed side blocks and between each side block and the block; at least 3 side blocks (31) are arranged in connection to each bearing element (3). The utility model can effectively prevent uneven deformation caused by local stress, improve the operational reliability and the service life and reduce the cost for storing spare parts.
Description
Technical field
The utility model relates to the Equipment for Heating Processing field in a kind of machinery manufacturing industry, particularly relates to a kind of can effectively preventing and produces distortion, can improve convection current plate in the middle of the bell furnace in serviceability and work-ing life again because of local pressure; It especially is suitable for supporting use in the bell type annealing furnace.
Background technology
At present, carrying out the annealed coil of strip in bell type annealing furnace need add middle convection current plate between upper and lower layer coil of strip, with the convection effects of raising heated air, thus the homogeneity of raising heat conduction efficiency, raising heating case temperature.The convection current plate is the monoblock type welded construction in the middle of existing, and referring to shown in Figure 4, it is to be welded to each other by monoblock type bearing plate part 1 and monoblock type web plate part 2 to form, and this bearing plate part 1 scantlings of the structure is more abundant, and rigidity is better, is not easy distortion; And the scantlings of the structure of described web plate part 2 is thinner relatively, and rigidity is relatively poor, if under certain stress, be easy to generate distortion.Because the convection current plate is the integral solder structure in the middle of described,,, will causes stone tongs can't clamp and can't continue and use if after this centre convection current plate deflection exceeds certain value in case local generation distortion will cause bulk deformation.Run in process of production described in the middle of convection current plate deflection and can't clamp the time, will cause the termination of subsequent job, thereby influence is produced.Described convection current plate distortion situation is especially serious when not being very neat at the steel flanging part of being produced.
In a single day the convection current plate deformed in the middle of existing monoblock type was welded, and the back is difficult repairs, and causes the expense of spare part higher.
The utility model content
Technical problem to be solved in the utility model be exactly provide at the present situation of above-mentioned prior art a kind of have prevent to produce the bell furnace centre convection current plate that uneven distortion can improve working reliability and work-ing life because of local pressure.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: convection current plate in the middle of a kind of bell furnace, it comprises bearing plate part and web plate part, it is characterized in that: this bearing plate partly is made up of the load bearing element that interconnective, a plurality of also its avris are provided with the limit piece that connects usefulness, described web plate is partly by described limit piece alternative expression adjacent superimposed composition, to prevent the distortion that is produced because of local pressure to greatest extent and to improve its working reliability and work-ing life.
Can adopt between described limit piece and the described load bearing element to be welded to connect, the technology that is welded to connect is simpler and easy, and it is better to be connected the back integral rigidity between this limit piece and the load bearing element.
Connection between the described adjacent superimposed limit piece preferably is set to bolt and connects, and bolted method it produce with assembling all comparatively easy.
Between the described adjacent superimposed limit piece and can be provided with tolerance clearance between this limit piece and the described bolt, the function in this gap be make between each described limit piece and described bolt and described limit piece between have certain relative active condition, prevent that this limit piece is out of shape owing to stressed.
The described connection by a plurality of load bearing elements welds after last limit piece connection combination is finished in the combination again, to realize good whole rigidity.
The utility model is provided with the quantity of the limit piece of the quantity of described load bearing element and this load bearing element according to specification in the described supporting bell type annealing furnace.
The quantity of the described limit piece that connects on each described load bearing element preferably is set to 3 at least.
The utility model can effectively prevent the uneven distortion that produces of local pressure, and improves working reliability and work-ing life, can reduce the expense of spare part simultaneously.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 to Fig. 3 shows an embodiment of the middle convection current plate of a kind of bell furnace of the utility model, it comprises that also its avris of interconnective polylith is provided with the load bearing element 3 of the limit piece 31 that connects usefulness, adopts between this load bearing element 3 and this limit piece 31 to be welded to connect.
Superimposed connection between the limit piece 31 of the alternative expression that connection between the adjacent load bearing element 3 is adopted, and lock with bolt 5.
Leave certain flexible gap between the limit piece 31 and between limit piece 31 and the bolt 5, can make between each limit piece 31 and bolt and limit piece 31 between certain relative active leeway is arranged, be out of shape owing to stressed to prevent this limit piece 31.
The utility model is provided with the quantity of the limit piece 31 of the quantity of load bearing element 3 and each load bearing element 3 according to the specification of bell furnace;
The utility model is to be combined by 20 load bearing elements 3 independently, and 20 load bearing elements 3 just can form complete middle a convection current plate by mutual connection combination, welds after wherein limit piece 31 needs of last piece assembled again.
In order to guarantee the connection reliability between the described load bearing element 3, the quantity of the limit piece 31 of each load bearing element 3 is set to 3 at least usually.
Use in miscellaneous equipment if the utility model is supporting, then determine the quantity of the limit piece that the quantity of described load bearing element is connected with this load bearing element, and be combined to form a complete middle convection current plate by mutual connection according to this specification of equipment.
The utility model is the characteristics according to convection current plate itself, and the load bearing element 3 that the integral solder formula is made into polylith assembles, and has in use that distortion is little, reliability is high and the advantage of long service life, can reduce again on the other hand because of deposit spare part required expense.
