Description
Technical field
The present invention relates to a kind of aerial resistance furnace heating element arrangement mode.
Background technology
Industrial resistance furnace as heating element heater, converts electric energy to heat energy by it typically by lectrothermal alloy wire, heat energy heat processed workpiece.In order to ensure the quality of heat treatment of workpieces, the furnace temperature decision of stove is a critically important index.In order to reach this index request, it is possible to take diversified means.Usual heating element heater is evenly arranged in burner hearth, and this mode can only meet the stove that furnace temperature decision requirement is general.And along with the development of aeronautical and space technology, the requirement of the furnace temperature decision of aviation industrial heat treatment furnace is also more and more higher, the furnace temperature decision of such as heat treating trolley furnace requires to be ± 5 DEG C (being generally ± 10 DEG C), and this is accomplished by the preferred arrangement mode of a kind of new heating element heater.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of aerial resistance furnace heating element arrangement mode, to overcome the defect existed in prior art.
The technical scheme is that a kind of aerial resistance furnace heating element arrangement mode, it is characterized in that: the refractory material supporting brick in the burner hearth of body of heater is provided with heating unit district, in heating unit district, be provided with installing the space region of heating element heater unit；Space region is divided into can place 6 heating element heater unitary spaces, the described heating element heater unit in space region has 6, the screw pitch being coiled in two ends 1/4 length of 6 heating element heater unit is T, the screw pitch being coiled in 1/2 middle length is 2T, successively from top to bottom, the series connection of the heating element heater unit in space region is followed by power supply.
Described heating element heater unit is lectrothermal alloy wire.
The technique effect of the present invention is:
The unit of heating element heater is processed into different pitch T, according to the burner hearth demand to heat, the unit optimization of heating element heater is arranged in rational position.Can be spaced, it is also possible to be do not have spaced, by the layout of multiple combination, reach the requirement of the uniformity of furnace temperature.Such as at certain high temperature car type furnace, the size length in its effective operating room is 4500mm × wide 2200mm × high 1300mm.Being postponed by optimized for the unit of heating element heater cloth, furnace temperature decision is ± 3.15 DEG C when 500 DEG C, is ± 2.8 DEG C when 940 DEG C, is ± 2.7 DEG C when 1010 DEG C, the requirement less than or equal to ± 5 DEG C.

Fig. 2 is pitch is the T+2T heating element heater unit mixed；
Fig. 3 is pitch is six standard heating element heater unit combination of T+2T；
Accompanying drawing is labeled as: 1. body of heater, 2. burner hearth, 3. heating unit district, 4. heating element heater unit, 5. space region.
Detailed description of the invention
The invention belongs to the preferred arrangement of a kind of aerial resistance furnace heating element arrangement mode, particularly heating element heater and improve the temperature uniformity of aviation industrial resistance furnace.As it is shown in figure 1, it is to be provided with heating unit district 3 on the refractory material supporting brick in the burner hearth 2 of body of heater 1, in heating unit district 3, it is provided with installing the space region 5 of heating element heater unit 4；Heating element heater unit 4 series connection in different spaces district 5 is followed by power supply.
As shown in Figure 2, pitch is the heating element heater unit of T+2T mixing, and heating element heater unit lectrothermal alloy wire coiling pitch not waited, at the length direction of heating element heater unit, the screw pitch being coiled in 1/4 length at two ends is T, and the screw pitch being coiled in 1/2 middle length is 2T.
Lectrothermal alloy wire or be the heating element heater unit not waited for coiling pitch along its length, the screw pitch being coiled in 1/4 length at two ends is T, and the screw pitch being coiled in 1/2 length of centre is 2T.
Fig. 3 is pitch is six standard heating element heater unit combination of T+2T.
6 heating element heater unit that pitch is T+2T are combined, is arranged in putting on a brick in heating furnace burner hearth, is all together in series, be connected to power supply, form a thermal treatment zone.
It practice, the size of the thermal treatment zone and quantity are determined according to the designed calculating of size of burner hearth size of heating furnace.In production, the heating element heater unit of different forms, it is processed into all size on demand, the heating unit district (3) adding needs by design drawing is fixed, and obtains the thermo parameters method of the best.
In embodiment directly not corresponding with claims, but embodiment is the thought provided by summary of the invention is designed, and is as the criterion with claim.
