Described heating element heater unit is lectrothermal alloy wire, and lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of T。
Described lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of 2T。
Described 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。
In described heating element heater unit, pitch is four heating element heater unit of 1T putting on a brick of being arranged in heating furnace burner hearth 1,2 and 4,5 positions, space region, is all together in series, is connected to power supply, and 3,6 space region are room, form a thermal treatment zone。
In described heating element heater unit pitch be 4 heating element heater unit of 2T be arranged in heating furnace burner hearth 1,2 and 4, the putting on a brick of the position of 5 space region, be all together in series, be connected to power supply, 3,6 space region are room, form a thermal treatment zone。
In described heating element heater unit, pitch is 4 heating element heater unit of T+2T putting on a brick of being arranged in heating furnace burner hearth 1,2 and 4,5 positions, space region, is all together in series, is connected to power supply, and 3,6 space region are room, form a thermal treatment zone。
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。

Detailed description of the invention
The invention belongs to the preferred arrangement of a kind of quaternary allocatable aero resistance furnace heater, 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 some heating unit districts 3 on the refractory material supporting brick in the burner hearth 2 of body of heater 1, in each 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 the same space district 5 is followed by power supply。
As in figure 2 it is shown, heating unit district 3 is divided into 6 locus, 6 locus can be placed 4 heating element heater unit 4 as required and are fixed in space region 5, and 4 heating element heater unit are to fix by 1,2 positions, space region and 4,5 positions, space region。
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。
As shown in Figure 4, lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of 2T。
As it is shown in figure 5, 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。
Realizing an embodiment of above-mentioned target as shown in Figure 6, Fig. 6 is pitch is four standard heating element heater unit combination (2 rooms) of 1T。What be arranged in heating furnace burner hearth by four heating element heater unit that pitch is 1T 1,2 and 4,5 positions, space region puts on a brick, is all together in series, is connected to power supply, and 3,6 space region are room, form a thermal treatment zone。
Realize the further embodiment of above-mentioned target as it is shown in fig. 7, Fig. 7 is pitch is four standard heating element heater unit combination (2 rooms) of 2T。4 heating element heater unit that pitch is 2T are arranged in heating furnace burner hearth 1,2 and 4, the putting on a brick of the position of 5 space region, be all together in series, be connected to power supply, 3,6 space region are room, form a thermal treatment zone。
Next multi-form embodiment is provided to absolutely prove advantages of the present invention。
Fig. 8 is pitch is four standard heating element heater unit combination (2 rooms) of T+2T。
What be arranged in heating furnace burner hearth by 4 heating element heater unit that pitch is T+2T 1,2 and 4,5 positions, space region puts on a brick, is all together in series, is connected to power supply, and 3,6 space region are room, form 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 the present invention is that 4 same form heating element heaters are placed in 6 spaces by 1,2 positions, space region and 4,5 space region position groupings。
