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 utility model will solve provides and is adapted to aviation and uses the resistance furnace heater with the hybrid aviation of the quaternary of resistance furnace optimal design.
The technical scheme of the utility model is: the resistance furnace heater is used in the hybrid aviation of a kind of quaternary; 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 4 multi-form heating element heater unit are placed in 6 locus, are connected to power supply after the heating element heater units in series 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.
Pitch is that 1 heating element heater unit of 1T is arranged in putting on the brick of 5 space region positions in the heating furnace burner hearth in the described heating element heater unit; With pitch is that 2 heating element heater unit of 2T are arranged in putting on the brick of 2,6 space region positions in the heating furnace burner hearth; With pitch is that 1 heating element heater unit of 1T+2T is arranged in putting on the brick of 1 space region position in the heating furnace burner hearth; All be together in series, be connected to power supply, form a thermal treatment zone.
The technique effect of the utility model 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.
