Description
Technical field
The utility model relates to a kind of aviation and uses the resistance furnace heater, and the resistance furnace heater is used in particularly a kind of even formula aviation of ternary that adapts to even distribution heating unit.
Background technology
The industry resistance furnace uses lectrothermal alloy wire as heating element heater usually, converts electric energy to heat energy through it, is heated the workpiece that is processed by heat energy.In order to guarantee the quality of heat treatment of workpieces, the furnace temperature uniformity of stove is a very important index.In order to reach this index request, can take diversified means.Usually heating element heater is evenly to arrange in burner hearth, and this mode can only satisfy the general stove of furnace temperature uniformity requirement.And along with development of aviation and aerospace technology; Also increasingly high to aviation with the requirement of the furnace temperature uniformity of industrial heat-treatment furnace; For example the furnace temperature uniformity of heat treatment car type furnace requires to be ± 5 ℃ (being generally ± 10 ℃), and this just needs a kind of preferred arrangement mode of new heating element heater.
The utility model content
The technical problem that the present invention will solve provides and is adapted to aviation and uses the resistance furnace heater with the even formula aviation of a kind of ternary of resistance furnace optimal design.
Technical scheme of the present invention is: the resistance furnace heater is used in the even formula aviation of a kind of ternary; It is characterized in that: the refractory material in the burner hearth of body of heater supports brick and is provided with some heating units district, is provided with the space region that the heating element heater unit can be installed in each heating unit district; Space region is divided into can place position, 6 heating element heater unitary spaces; 3 heating element heater unit are placed in 6 locus; 1 space region in space, 3 heating element heater unit distributes, and is placed on to be connected to power supply after connecting in heating element heater unit (4) the same space district in.
Described heating element heater unit is a 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.
Technique effect of the present invention is:
Unit to heating element heater is processed into different pitch T, according to the demand of burner hearth to heat, the unit optimization of heating element heater is arranged in rational position.Can be spaced, also can be not at interval, with the layout of multiple combination, reaches the requirement of the uniformity of furnace temperature.For example at certain high temperature car type furnace, the size in its effective operating room is long to be 4500mm * wide 2200mm * high 1300mm.After preferred arrangement, the furnace temperature uniformity is ± 3.15 ℃ in the time of 500 ℃, in the time of 940 ℃, is ± 2.8 ℃, in the time of 1010 ℃, is ± 2.7 ℃, smaller or equal to ± 5 ℃ requirement with the unit of heating element heater.

The specific embodiment
The heating element heater that the invention belongs to a kind of industrial resistance furnace arranges that particularly the preferred arrangement of heating element heater has improved the temperature uniformity of aviation with industrial resistance furnace.As depicted in figs. 1 and 2, it is that refractory material in the burner hearth 2 of body of heater 1 supports brick and is provided with some heating units district 3, is provided with the space region 5 that heating element heater unit 4 can be installed in each heating unit district 3; Space region 5 is divided into can place 4 locus, 6 heating element heater unit; 3 heating element heater unit 4 are placed in 6 locus; 3 heating element heater unit 4 are separately fixed in the different space region 5; 1 space region in space, 3 heating element heater unit 5 distributes, and is placed on respectively to be connected to power supply after connecting in 5 interior heating element heater unit 4, the same space district.
As shown in 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 shown in Figure 5, and heating unit district 3 is divided into 6 spaces, and 3 heating element heater unit 4 are placed on respectively 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 that pitch is three standard heating element heater unit combination (3 rooms are arranged) of 1T.With pitch is that 3 heating element heater unit of 1T are arranged in putting on the brick of 1,3,5 positions in the heating furnace burner hearth, all is together in series, and is connected to power supply, and 2,4,6 is the room, and they form a thermal treatment zone jointly.
Embodiment 2 is as shown in Figure 6, and it is that pitch is three standard heating element heater unit combination (3 rooms) of 2T.With pitch is that 3 heating element heater unit of 2T are arranged in putting on the brick of 1,3,5 positions in the heating furnace burner hearth, all is together in series, and is connected to power supply, and 2,4,6 is the room, forms a thermal treatment zone jointly.
Because different space environments and different size of burner hearth and different heat requirements, combining form also adapts to different requirement, and the present invention is that 3 heating element heater unit have equally distributed compound mode at interval.
