Description
Technical field
The present invention relates to a kind of aviation resistance furnace heater, particularly a kind of ternary interval-free aviation resistance furnace heater.
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 ternary interval-free aviation resistance furnace heater being adapted to aviation resistance furnace optimization design.
The technical scheme is that a kind of ternary interval-free aviation resistance furnace heater, 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, and 3 heating element heater unit are individually placed in different space region, and 3 heating element heater unit are without spaced apart each other, and the heating element heater unit series connection in different spaces district is followed by power supply.
Described heating element heater unit has 3,3 screw pitch cycles are the heating element heater unit of T or 2T, be arranged in order and be individually placed in adjacent 3 different space region, below three space region (5) be empty, the heating element heater unit series connection in different spaces district is followed by power supply.
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 non-gap, 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.

Below in conjunction with embodiment accompanying drawing, the present invention will be further described:
Fig. 1 is embodiment of the present invention structural representation；
Fig. 2 is heating unit plot structure schematic diagram；
Fig. 3 is pitch is T heating element heater unit；
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 ternary interval-free aviation resistance furnace heater, particularly heating element heater and improve the temperature uniformity of aviation industrial resistance furnace.Embodiment, 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, is provided with installing the space region 5 of heating element heater unit 4 in heating unit district 3；3 heating element heater unit 4 arrange in order successively and are separately fixed in adjacent different spaces district 5 as shown in Figure 2, i.e. 6 space region 5, upper 3 space region are placed with different heating element heater unit 4 successively respectively, three space region 5 form the arrangement of ternary gapless type for room below, and heating element heater unit 4 series connection in different spaces district 5 is followed by power supply.
As it is shown on figure 3, heating element heater unit 4 can be lectrothermal alloy wire.Lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of T.
Embodiment 1 is as shown in Figure 1, Figure 2, Figure 3 shows, what be arranged in heating furnace burner hearth by 3 heating element heater unit that pitch is 1T position, space region 1,2,3 puts on a brick, 3 heating element heater unit 4 are all together in series, it is connected to power supply, space region 4,5,6 is room, and they collectively constitute a thermal treatment zone.
Due to different spatial environmentss with different size of burner hearth and different thermal requirement, combining form is also adapted to different requirements, and above-described embodiment is the compound mode of 3 heating element heater unit gapless types arrangements, to adapt to specific requirement.
