Abstract
The utility model discloses a hearth plate with a hollow cellular structure for a heat treatment furnace, which is composed of a cellular framework, a side plate, a panel and a bottom plate, wherein the bottom plate, the cellular framework and the panel are stuck from bottom to top; the side plate is arranged on the edge of the cellular framework; the cellular framework and the panel are arranged at the inner side of the side plate. The hearth plate is made of metal material with heat resistance and corrosion resistance. The hearth plate with the structural style has good bearing capacity. Thus, the weight of the hearth plate is reduced to a great extent, the utility model can bear high temperature oxidation and cavitation erosion, and the heat fatigue resistance of the hearth plate is effectively improved. The hearth plate with the structural style has the advantages of strong anti-fatigue capability, light weight, less stored heat, high heating-up speed and energy and material saving; the service life of the utility model can be extended by more than 3 times; production efficiency can be effectively raised; cost can be dropped by 30-40%.
Description
Technical field
The utility model belongs to the improvement technology of the component-drop-bottom of the employed industrial furnace of thermal treatment, is specially a kind of hollow grid structure drop-bottom, is particularly useful for the high-temperature heat treatment stove.
Background technology
The drop-bottom of industrial heat treatment furnace is used to carry heat treated part, it is the very big consumable accessory of a kind of consumption, especially the Working environment of high-temperature heat treatment stove is very abominable, furnace temperature is in more than 1000 ℃ for a long time, drop-bottom not only will through by compression with the effect of stretching repeated load, also to stand the erosion of high temperature oxidation stability gas.For a long time, the employed drop-bottom of high-temperature heat treatment stove, mostly be to adopt the unitary solid cast structure, the weight of this structure formation drop-bottom is big, energy consumption is high, the life-span is short, cost is high, average use will be scrapped because of heat fatigue cracking, distortion in about 1 year, with the RJX75-12 resistance furnace is example, and changing a drop-bottom just needs ten thousand yuan of expensive 2.6-3, makes the cost of thermal treatment enterprise raise.
The utility model content
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of long service life, cost is low, in light weight, energy consumption is low hollow grid structure drop-bottom.
To achieve these goals, the technical solution of the utility model is:
A kind of hollow grid structure drop-bottom, drop-bottom comprises grid frame, panel, panel and grid frame stack up and down.
Described grid frame edge is provided with side plate, and grid frame and panel place the side plate inboard.
Between side plate and panel, leave the gap.
Be provided with base plate below the described grid frame, side plate is installed on the base plate.
Described drop-bottom also comprises base plate, side plate, base plate, grid frame, panel stack by order from bottom to top, base plate, grid frame, panel are rectangular parallelepiped, grid frame three sides are provided with side plate, the side plate top curves " hook " shape passage to the inside, upwards be bent into square with the corresponding panel of side plate two parallel surfaces two ends, this bending part is corresponding with " hook " shape passage of side plate, panel inserts by " hook " shape passage of bending part along the parallel both sides of side plate, and whole drop-bottom forms " drawer " shape structure.
Described drop-bottom also comprises base plate, side plate, and base plate, grid frame, panel stack by order from bottom to top, and base plate, grid frame, panel are non-standard shape, and side plate is installed on the grid frame edge, and grid frame and panel place the side plate inboard.
The hollow grid drop-bottom of the utility model is compared with the solid cast structure drop-bottom of tradition, has the following advantages:
1, the hollow grid structure drop-bottom of the utility model is made of grid frame, side plate, panel, base plate, and what the drop-bottom material was selected for use is heat-resisting, corrosion resistant metallic substance.Grid frame is a kind of perfectly load bearing structure on mechanics for the hollow grid structure of net, and the drop-bottom of hollow grid structure form possesses good weight capacity, is out of shape little, easy to maintenance; Adopt the structure of grid frame coated with panel, alleviated the weight of drop-bottom to a great extent, compare with the traditional burner base plate, weight can alleviate 60-70%; Heat-resisting, corrosion resistant metallic substance has good high temperature resistant, oxidation-resistance, simultaneously, again because the thinner thickness of material, in intensification and temperature-fall period, the hollow grid structure drop-bottom temperature difference everywhere is very little, and the numerical value of the alternating thermal stress that is produced in drop-bottom inside also is very little therefrom, the probability that produces heat fatigue cracking can significantly reduce, thereby improved the thermal fatigue resistance ability of drop-bottom, compared with the traditional burner base plate, can prolong more than 3 times work-ing life.
2, the drop-bottom of the utility model structure formation, heat storage capacity is few, and heat-up rate is fast, can enhance productivity effectively; Save the energy and material, cost can reduce by 30～40%, has very remarkable economic efficiency, and its market application foreground is very wide, has promotional value especially.

Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation in further detail.
As Figure 1-3, the drop-bottom that the utility model is used for box-type furnace is by base plate 1, grid frame 2, panel 3, side plate 4 constitutes, base plate 1, grid frame 2, panel 3 stacks by order from bottom to top, grid frame 2 three sides are provided with side plate 4, side plate is installed on the base plate, side plate 4 tops curve " hook " shape passage 5 to the inside, upwards be bent into square with 4 liang of corresponding panels of parallel surface of side plate two ends, this bending part 6 is corresponding with " hook " shape passage 5 of side plate 4, panel 3 inserts by " hook " shape passage 5 of bending part 6 along side plate 4 parallel both sides, and whole drop-bottom forms " drawer " shape structure.Grid frame 2 is main positions of load-bearing, its thickness designs according to the load-bearing needs, the thickness of panel only is about 4-6mm, between side plate 4 and panel 3, all leave certain clearance, panel is free to slide, drop-bottom can freely be stretched in heat treatment process, avoid deforming and warpage because of thermal expansion.
As shown in Figure 4, for make grid frame 2 dress during workpiece not the refractory brick to furnace bottom produce shearing action, below skeleton, can be placed with base plate 1.
The utility model can be used for the drop-bottom of cylindrical heat treatment furnace, as long as base plate, grid frame, panel are made cylindrical, annular side plate is installed on the grid frame edge and gets final product.As required, the utility model can also be used for other non-standard shape (different shape) drop-bottoms, and base plate, grid frame, panel are made corresponding arbitrary shape.
The utility model drop-bottom can be weldment or foundry goods.
