The optimized ternary aviation resistance furnace heater is applied to the optimized design of an aviation resistance furnace.
Description
Technical field
The ternary aviation that the present invention relates to a kind of optimization uses the ternary aviation of resistance furnace heater, particularly a kind of optimization to use the resistance furnace heater.
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.
Summary of the invention
Technical scheme of the present invention is: the resistance furnace heater is used in a kind of ternary aviation of optimization; 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; Described heating element heater unit is a lectrothermal alloy wire; Lectrothermal alloy wire coiling pitch along its length is that the screw pitch of coiled is T in 1/4 length at two ends, and the screw pitch of coiled is 2T in 1/2 length of centre, is connected to power supply after the heating element heater units in series in the same space district.
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.It is non-interval, 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.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the present invention is further specified:
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is that pitch is the heating element heater unit that T+2T mixes;
Fig. 3 is a heating unit plot structure sketch map.
Reference numeral is: 1. body of heater, 2. burner hearth, 3. heating unit district, 4. heating element heater unit, 5. space region.
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.Embodiment is as shown in Figure 1; 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; Be 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, 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 the space region 5, are not connected to power supply after heating element heater unit 4 series connection on the coordination in the same space district 5.
As shown in Figure 2, heating element heater unit 4 can be lectrothermal alloy wire.Lectrothermal alloy wire or be that the coiling pitch is the heating element heater unit that do not wait along its length, the screw pitch of the interior coiled of 1/4 length at two ends is T, the screw pitch of coiled is 2T in 1/2 length of centre.
As shown in Figure 3, its pitch is three standard heating element heater unit combination (3 rooms) of T+2T.With pitch be 1T+2T be arranged in the putting on the brick of 1,2,3 rooms in the heating furnace burner hearth, 3 heating element heater unit on the isotopic number all are not together in series, and are connected to power supply, 4,5,6 figure places are rooms, they form 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 foregoing description is the compound mode that gapless type that 3 heating element heater cell pitch are T+2T is arranged, to adapt to specific requirement.
