Abstract
The utility model provides a pair of resistance furnace, the temperature to furnace body inside that is provided with on the lateral wall of the internal surface of stove outer covering that adiabatic fibrofelt can be fine keeps warm, the the scattering and disappearing of separation energy, the resistance wire is directly shelved between the resistant firebrick of the light of furnace body, like this can be to the temperature even heating in the whole vertical space of furnace body, and the condition of bottom and top excessive temperature differentials can not appear, the diameter of resistance wire is progressively held to stove far away from nearly stove end and is steadilyd decrease, because the diameter of this resistance wire progressively reduces to the resistance progressively changes, and then the temperature of furnace body progressively changes. Like this, not only need not to set up a large amount of current controlling means, effectively reduced the preparation cost of pot arch, the utility model discloses well adoption aluminium titanium alloy is more pliable and tougher and durable as the material of resistance wire.
Description
Technical field
This utility model relates to a kind of resistance furnace.
Background technology
Resistance furnace is to utilize electric current to make heating or heating dielectric heat in stove, thus adds workpiece or material
The industrial furnace of heat.Resistance furnace is used for heating, metal heat treatmet heating, pricker before metal forging in mechanical industry
Weldering, powder metallurgy sintered, glass ceramics roasting and annealing, low-melting-point metal fusing, sand mold and paint film
Be dried etc..The depth bearing of trend of body of heater in prior art, the temperature in stove is progressively reduced or increased.Mesh
Before, the conventional practice is along the identical resistance wire of the depth bearing of trend subsection setup diameter of body of heater, but often
The resistance wire of section passes to different operating currents.Have a disadvantage in that: need to arrange several current control devices,
Thus add the preparation cost of pot arch；Each several part electric current is difficult to reach accurately to control, thus makes actual
In with, the temperature of each section may be identical.
Utility model content
For solving above-mentioned technical problem, this utility model provides a kind of novel resistance furnace.
A kind of resistance furnace, it includes furnace shell, the sidewall of the inner surface of described furnace shell is provided with heat-insulating fiber
Felt, the middle part of described furnace shell is provided with the body of heater depositing material, and described body of heater is to be built by light fire brick
Block forms, if the bottom of described body of heater is equipped with dried layer heavy refractory brick, between described light fire brick
Being arranged at intervals with resistance wire, described resistance wire includes that resistance wire body, described resistance wire body are cylinder
Shape, nearly stove end that described resistance wire body includes stretching to furnace interior and the remote stove end away from furnace interior,
The diameter of described nearly stove end is more than the diameter of remote stove end, and the reduction of diameter is in the shape that progressively successively decreases.
Preferably, described resistance wire is made up of aluminum titanium alloy.
Preferably, it is filled with expanded perlite between described heat-insulating fiber felt and body of heater.
A kind of resistance furnace that this utility model provides, it has the beneficial effects that: on the sidewall of the inner surface of furnace shell
It is provided with heat-insulating fiber felt to can be good at the temperature of furnace interior is incubated, intercepts scattering and disappearing of energy；
Resistance wire is directly held between the light fire brick of body of heater, so can be to the temperature of whole body of heater longitudinal space
Degree uniformly heating, does not haves the situation of bottom and top excessive temperature differentials；The diameter of resistance wire is progressively from nearly stove
End successively decreases to remote stove end, and owing to the diameter of this resistance wire progressively reduces, thus resistance is changed stepwise, Jin Erlu
The temperature of body is changed stepwise.So, not only without arranging a large amount of current control device, effectively reduce and heat
The preparation cost of stove；This utility model use aluminum titanium alloy more pliable and tougher and durable as the material of resistance wire.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described.
Accompanying drawing 1 is the structural representation of resistance furnace in this utility model；
Accompanying drawing 2 is the structural representation of resistance wire in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described.
The present embodiment as depicted in figs. 1 and 2,
A kind of resistance furnace, it includes furnace shell 1, the sidewall of the inner surface of described furnace shell 1 is provided with thermal insulation
Fiber felt 2, the middle part of described furnace shell 1 is provided with the body of heater 3 depositing material, and described body of heater 3 is by gently
Refractory brick 4 assembles and forms, if the bottom of described body of heater 3 is equipped with dried layer heavy refractory brick 5, described
It is filled with expanded perlite between heat-insulating fiber felt 2 and body of heater 3, is spaced between described light fire brick 4
Being provided with resistance wire 6, described resistance wire 6 includes that resistance wire body 61, described resistance wire body 61 are
Cylindric, described resistance wire body 61 includes stretching to the nearly stove end 62 within body of heater 3 and away from body of heater 3
Internal remote stove end 63, the diameter of described nearly stove end 62 is more than the diameter of remote stove end 63, and the reduction of diameter
In the shape that progressively successively decreases, described resistance wire 6 is made up of aluminum titanium alloy.
A kind of resistance furnace that this utility model provides, the sidewall of the inner surface of furnace shell is provided with heat-insulating fiber felt
Can be good at the temperature of furnace interior is incubated, intercept scattering and disappearing of energy；Resistance wire is directly held on
Between the light fire brick of body of heater, so can be to the uniform heating temperature of whole body of heater longitudinal space, will not
Bottom appearance and the situation of top excessive temperature differentials；The diameter of resistance wire progressively successively decreases to remote stove end from nearly stove end,
Owing to the diameter of this resistance wire progressively reduces, thus resistance is changed stepwise, and then the temperature of body of heater is changed stepwise.
So, not only without arranging a large amount of current control device, the preparation cost of pot arch is effectively reduced；This reality
More pliable and tougher and durable as the material of resistance wire with novel middle employing aluminum titanium alloy.
The described above of embodiment disclosed in the utility model, makes professional and technical personnel in the field be capable of
Or use this utility model.Multiple amendment to these embodiments for those skilled in the art will
Being apparent from, generic principles defined herein can be without departing from spirit of the present utility model or model
In the case of enclosing, realize in other embodiments.Therefore, this utility model is not intended to be limited to institute herein
These embodiments shown, and it is to fit to consistent with principles disclosed herein and features of novelty the widest
Scope.
