Abstract
The invention relates to a triple-element heater for an aviation resistance furnace, in particular to a triple-element pitch-T heater for an aviation resistance furnace, which is characterized in that heating unit areas are arranged on refractory support bricks inside a hearth of a furnace body, space areas for mounting heating element units are reserved in the heating unit area, each space area is divided into six spaces for holding the heating element units, three different heating element units are disposed in the six spaces respectively, each heating element unit is an electrothermal alloy wire which is wound lengthwise into the electrothermal alloy wire with a helical pitch T, and the heating element units in the same space area are serially connected prior to being connected to a power source. The triple-element heater is applicable to optimized design of aviation resistance furnaces.
Description
Technical field
The present invention relates to a kind of ternary aviation and use the resistance furnace heater, the resistance furnace heater is used in particularly a kind of ternary 1T aviation.
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
The technical problem that the present invention will solve provides and is adapted to aviation and uses the resistance furnace heater with the ternary aviation of resistance furnace optimal design.
Technical scheme of the present invention is: the resistance furnace heater is used in a kind of ternary 1T aviation; 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; 6 locus are placed 3 different heating element heater unit respectively; Described heating element heater unit is a lectrothermal alloy wire; Lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of T, 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 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 invention is further specified:
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is a heating unit plot structure sketch map;
Fig. 3 is that pitch is the heating element heater cell schematics of 1T.
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 invention belongs to a kind of ternary 1T aviation uses the preferred arrangement of resistance furnace heater, particularly heating element heater to improve the temperature uniformity of aviation with industrial resistance furnace.Embodiment such as Fig. 1 and Fig. 2, shown in Figure 3; 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 position, 6 heating element heater unitary spaces, and 6 locus are placed 3 different heating element heater unit respectively; Described 3 heating element heater unit are lectrothermal alloy wire; Lectrothermal alloy wire coiling pitch along its length is the lectrothermal alloy wire of T, and 3 heating element heater unit 4 are separately fixed in the different space region 5, i.e. 6 space region 5; Last 3 space region are placed with different heating element heater unit 4 successively respectively; Below three space region (5) be the room, both 3 heating element heater unit were arranged in the putting on the brick of 1,2,3 positions of space region 5 in the heating furnace burner hearth, 4,5,6 of space region 5 is the room; Their common ternary gapless types that forms are arranged, and are connected to power supply after heating element heater unit 4 series connection in the same space district 5.
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 3 compound modes that 1T heating element heater unit gapless type is arranged, to adapt to specific requirement.
