Degree.
2. cast iron, magnesia density is all very big, and thermal capacitance is accordingly also big, causes furnace temperature to start slow.And after having used still
There is amount of heat to be stored on stone or metal plate for standing a stove on as a precaution against fire, waste the energy.
3. because of heating wire, magnesia, cast iron is contacted, and cast iron is conductive.If making moist, magnesium oxide insulated hydraulic performance decline.
Cause electric leakage.
Utility model content
The purpose of this utility model is to provide a kind of electric furnace that may replace traditional cast iron stone or metal plate for standing a stove on as a precaution against fire, and its temperature is high, and not oxygen
Change, boiler face safe temperature greatly improves cooking speed up to 600；Rate of rise in temperature is exceedingly fast, and has used the heat energy of rear residual
Seldom；Security performance is high, in the absence of the possibility of electric leakage.
To achieve the above object, the utility model provides following technical scheme：
A kind of electric furnace that may replace traditional cast iron stone or metal plate for standing a stove on as a precaution against fire of the present invention, including heating wire, insulating collar, heat-insulated bottom, devitrified glass
Plate, ceramics seat, the insulating collar are fixed on the edge at heat-insulated bottom, and the ceramics seat is mounted in insulating collar outside, the heating wire
On heat-insulated bottom, heating wire is connected with the wiring hole of ceramics seat, and the microcrystal glass plate is fixed on the top of insulating collar, institute
State and gap is provided between heating wire and microcrystal glass plate.
Wherein, the heating wire is some, and u-shaped spiraling is placed on heat-insulated bottom respectively, the insulating collar, heat-insulated
Bottom is made of aerosil nano material.
Compared with prior art, the beneficial effects of the utility model are：
1 temperature is high, and devitrified glass is resistant to 750 degree of high temperature, and does not aoxidize；Boiler face safe temperature is greatly improved up to 600
Cooking speed.
2 have but fallen magnesium oxide insulated material, and glass weight is far below cast iron, therefore rate of rise in temperature is exceedingly fast, and make
The heat energy remained after being finished is few.
3 because devitrified glass and heating wire not in contact with, and devitrified glass sheet is as insulator, so security performance is high,
In the absence of the possibility of electric leakage.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, in the utility model embodiment：
A kind of electric furnace that may replace traditional cast iron stone or metal plate for standing a stove on as a precaution against fire of the present invention, including heating wire, insulating collar, heat-insulated bottom, devitrified glass
Plate, ceramics seat, the insulating collar are fixed on the edge at heat-insulated bottom, and the ceramics seat is mounted in insulating collar outside, the heating wire
On heat-insulated bottom, heating wire is connected with the wiring hole of ceramics seat, and the microcrystal glass plate is fixed on the top of insulating collar, institute
State and gap is provided between heating wire and microcrystal glass plate.
The heating wire is some, and u-shaped spiraling is placed on heat-insulated bottom respectively, and the insulating collar, heat-insulated bottom are adopted
It is made of aerosil nano material.
Heating wire：Resistance wire is a kind of general electrical equipment for converting electrical energy into interior energy；Using ferrum-chromium-aluminum or nickel chromium triangle electricity
Its antioxygenic property of thermalloy is general all stronger.The main advantage and disadvantage of Aludirome series：Advantage：Fe-based perovskite-like oxide its make
High with temperature, maximum operation (service) temperature up to 1400 degree, bear by (0Cr21A16Nb, 0Cr27A17Mo2 etc.), long service life, surface
Lotus is high, antioxygenic property is good, resistivity is high, cheap etc..Shortcoming：Mainly elevated temperature strength is low, as temperature in use is raised
Its plasticity increases, and element is yielding, not flexible and reparation.The main advantage and disadvantage of nickel chromium triangle electrothermal alloy series：Advantage：Elevated temperature strength
It is high compared with ferrum-chromium-aluminum, it is unlikely to deform under applied at elevated temperature, its structure not malleable, plasticity preferably, is easily repaired, and its radiance is high, without magnetic
Property, corrosion resistance is strong, long service life etc..Shortcoming：Due to being made of more rare nickel metal material, therefore the series of products valency
Lattice are higher by ferrum-chromium-aluminum and are for up to several times, and temperature in use is low compared with ferrum-chromium-aluminum.
Aerosil nano material：
Replace nano-scale alumina to be added in 95 porcelain with aerosil (gas phase of white carbon black), can both play nanometer
The effect of grain, while it is again the particle of the second phase, not only improves intensity, the toughness of ceramic material, and improve material
The performances such as consistency and elasticity modulus, its effect is more more preferable than addition Al2O3.Using aerosil (gas phase of white carbon black) reflex
Ceramic substrate is closed, compactness, toughness and the finish of substrate is not only increased, and sintering temperature is greatly reduced.Additionally, gas phase
Silica (gas phase of white carbon black) application effect in the ceramic products such as foam ceramic filter, corundum ball is also very notable.95 porcelain are
Alumina powder is referred to as 95 alumina ceramics through the high-performance ceramic that mist projection granulating, hydrostatic pressing and high-sintering process are manufactured
Part.With hardness is high, wearability, good corrosion resistance the characteristics of.
Microcrystal glass plate：Microcrystal glass plate be it is a kind of by appropriate glass particle is sintered and crystallization, the microcrystal being made and
The mixture of glass.Its quality is hard, pollution-free in packed uniform, and production process, and product "dead" pollution in itself, is one
Plant new environment-friendly and green material.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
