Description
Technical field
The present invention relates to the ternary aviation resistance furnace heater of a kind of optimization, particularly the ternary aviation resistance furnace heater of a kind of optimization.
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 scheme is that the ternary aviation resistance furnace heater of a kind of optimization, it is characterized in that: the refractory material supporting brick in the burner hearth of body of heater is provided with some heating unit districts, in each heating unit district, be provided with installing the space region of heating element heater unit; Space region is divided into can place position, 6 heating element heater unitary spaces, 3 heating element heater unit are placed in 6 locus, described heating element heater unit is lectrothermal alloy wire, lectrothermal alloy wire coiling pitch along its length is the screw pitch being coiled in 1/4 length at two ends is T, the screw pitch being coiled in 1/2 middle length is 2T, and the heating element heater unit series connection in the same space 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. It is non-gap, reaches 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 heating element heater of a kind of industrial resistance furnace to arrange, particularly the preferred arrangement of heating element heater improves the temperature uniformity of aviation industrial resistance furnace. Embodiment is as 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, it is provided with installing the space region 5 of heating element heater unit 4 in each heating unit district 3, space region 5 is divided into can place 6 heating element heater unit 4 locus, and 3 heating element heater unit 4 are placed in 6 locus; 3 heating element heater unit 4 are separately fixed on the different room in space region 5, and in the same space district 5, the series connection of the heating element heater unit 4 on coordination is not followed by power supply.
As in figure 2 it is shown, heating element heater unit 4 can be lectrothermal alloy wire. 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.
As it is shown on figure 3, its pitch is T+2T three standard heating element heater unit combination (3 rooms). By pitch be 1T+2T be arranged in heating furnace burner hearth 1,2,3 rooms put on a brick, 3 heating element heater unit on isotopic number are not all together in series, and are connected to power supply, and 4,5,6 figure places are rooms, and they collectively constitute a thermal treatment zone.
Due to different spatial environmentss and different size of burner hearth and different thermal requirement, combining form is also adapted to different requirements, and above-described embodiment is 3 heating element heater cell pitch is the compound mode of gapless type arrangement of T+2T, to adapt to specific requirement.
