Description
Technical field
The present invention relates to a kind of ternary aviation resistance furnace heater, particularly a kind of ternary 1T 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 the ternary aviation resistance furnace heater being adapted to aviation resistance furnace optimization design.
The technical scheme is that a kind of ternary 1T 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 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, 6 locus place different 3 heating element heater unit respectively, described heating element heater unit is lectrothermal alloy wire, lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of T, 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 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.

Fig. 2 is heating unit plot structure schematic diagram;
Fig. 3 is pitch is the heating element heater cell schematics of 1T.
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 1T aviation resistance furnace heater, particularly heating element heater and improve the temperature uniformity of aviation industrial resistance furnace. implement such as shown in Fig. 1 and Fig. 2, Fig. 3, 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 position, 6 heating element heater unitary spaces, and 6 locus place different 3 heating element heater unit respectively, 3 described heating element heater unit are lectrothermal alloy wire, lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of T, 3 heating element heater unit 4 are separately fixed in different space region 5, 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) are room below, both 3 heating element heater unit were arranged in heating furnace burner hearth the 1 of space region 5, 2, 3 positions put on a brick, the 4 of space region 5, 5, 6 is room, they are collectively forming the arrangement of ternary gapless type, heating element heater unit 4 series connection in the same space district 5 is followed by power supply.
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 1T heating element heater unit gapless types arrangements, to adapt to specific requirement.
