Description

A kind of ternary uniform aero resistance furnace heater

Technical field

The present invention relates to a kind of aviation resistance furnace heater, particularly a kind of adaptation and be uniformly distributed the ternary uniform aero resistance furnace heater of heating unit.

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 uniform aero resistance furnace heater being adapted to aviation resistance furnace optimization design.

The technical scheme is that a kind of ternary uniform aero 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, 3 heating element heater unit are placed in 6 locus, 3 heating element heater unit spaced 1 space region distributions, are placed on the series connection of the heating element heater unit (4) in the same space district and are followed by power supply.

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.

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 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. As depicted in figs. 1 and 2, 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, 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, 3 heating element heater unit 4 are placed in 6 locus, 3 heating element heater unit 4 are separately fixed in different space region 5,3 spaced 1 space region 5 of heating element heater unit are distributed, and are individually positioned in the series connection of the heating element heater unit 4 in the same space district 5 and are 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.

As shown in Figure 4, lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of 2T.

Embodiment 1 is as it is shown in figure 5, heating unit district 3 is divided into 6 spaces, and 3 heating element heater unit 4 are individually positioned in different 3 spaces, and each heating element heater unit 4 has a space region 5 to be separated by each other. Fig. 5 is pitch is three standard heating element heater unit combination (having 3 rooms) of 1T. What be arranged in heating furnace burner hearth by 3 heating element heater unit that pitch is 1T 1,3,5 positions puts on a brick, is all together in series, is connected to power supply, and 2,4,6 is room, and they collectively constitute a thermal treatment zone.

As shown in Figure 6, it is pitch is three standard heating element heater unit combination (3 rooms) of 2T to embodiment 2. What be arranged in heating furnace burner hearth by 3 heating element heater unit that pitch is 2T 1,3,5 positions puts on a brick, is all together in series, is connected to power supply, and 2,4,6 is room, collectively constitutes 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 3 heating element heater unit have the equally distributed compound mode in interval.
