The utility model content
The technical problem that the utility model will solve provides and is adapted to aviation and uses the resistance furnace heater with the non-homogeneous formula aviation of the ternary of resistance furnace optimal design.
The technical scheme of the utility model is: the resistance furnace heater is used in the non-homogeneous 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, and 3 heating element heater unit are placed in 6 locus, and 3 heating element heater unit non-uniform Distribution are connected to power supply after heating element heater unit 4 series connection in the same space district.
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.
Described 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.
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 right and wrong at interval, reach 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 invention belongs to the non-homogeneous formula aviation of a kind of ternary uses the preferred arrangement of resistance furnace heater, particularly heating element heater to improve the temperature uniformity of aviation with industrial resistance furnace.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, 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 position, 6 heating element heater unitary spaces, and 4,3 heating element heater unit 4 non-uniform Distribution in 3 heating element heater unit are placed in 6 locus, is connected to power supply after heating element heater unit 4 series connection in the same space district 5.
As shown in Figure 2, heating unit district 3 is divided into 6 locus, and 6 locus can be placed 3 heating element heater unit 4 as required and are fixed in the space region 5.
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 1T.
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 it is that pitch is three standard heating element heater unit combination (3 rooms) of 1T.With pitch is putting on the brick of 3 heating element heater unit of 1T space region 5 of being arranged in 1,2,4 positions in the heating furnace burner hearth; 3 heating element heater unit all are together in series; Be connected to power supply, 2,5,6 space region are the room, and they form a thermal treatment zone jointly.
