Abstract

The utility model discloses a heat treatment electric furnace. The furnace comprises an external support frame, a furnace wall, a furnace bottom and a furnace door, wherein aluminum silicate fiber cotton is arranged between the support frame and the furnace wall; the furnace wall consists of asbestos plates; resistance belts are arranged on the inner sides of the furnace wall and the furnace door; and a far infrared material coating is arranged on the inner wall of the furnace wall. The furnace wall consists of the asbestos plates which have a better thermal insulation effect than fireproof bricks; and the aluminum silicate fiber cotton instead of perlite or vermiculite powder is used for thermal insulation, so that the weight of a furnace body is reduced, and the thermal insulation property of the electric furnace is improved.

Description

A kind of heat treatment electric furnace
Technical field
The utility model belongs to the heat treatment technics field, relates in particular to a kind of heat treatment electric furnace.
Background technology
On commercial production; Usually the quenching heating of workpiece is accomplished through electric furnace; Electric furnace comprises body of heater and heater, and body of heater comprises common formation such as furnace wall, drop-bottom and fire door, and furnace wall commonly used is to be built into by refractory brick; At the inboard fixed resistance silk of furnace wall and drop-bottom, heating can heat up after the energising.Above-mentioned electric furnace is because furnace wall is to be made up of refractory brick, and the heat insulation effect of refractory brick is not very good; And between furnace wall and outer support frame, adopting vermiculite power, perlite to be incubated usually, heat insulation effect is good inadequately.
The utility model content
To above-mentioned prior art, the technical problem that the utility model will solve provides a kind of heat treatment electric furnace of high insulating effect.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of heat treatment electric furnace; Comprise outer support frame, furnace wall, furnace bottom, fire door; Be provided with aluminosilicate fiber cotton between support frame and the furnace wall, said furnace wall is made up of asbestos board, and said furnace wall and fire door inboard are equipped with resistive band.
Further, the inwall of said furnace wall is provided with the far-infrared material coating.
Further, said resistive band is through linking up with the inwall that is placed in furnace wall and fire door uniformly.
Compared with prior art, the utlity model has following beneficial effect: furnace wall adopts asbestos board, than adopting refractory brick to have better heat insulation effect; Adopt alumina silicate fibre replacement perlite, vermiculite power to be incubated, both alleviated the weight of body of heater, improved the heat-insulating property of electric furnace simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
To combine the accompanying drawing and the specific embodiment that the utility model is done further to describe below.
Referring to Fig. 1, a kind of heat treatment electric furnace comprises outer support frame 1, furnace wall 2, furnace bottom 4, the fire door 5 of metal; Furnace chamber inside is provided with guide rail; Guide rail is provided with the stove car that can slide, and is provided with aluminosilicate fiber cotton 3 between support frame 1 and the furnace wall 2, and said furnace wall 2 is made up of asbestos board; Said furnace wall 2 is equipped with resistive band 6 with fire door 5 inboards; Said resistive band 6 is through linking up with the inwall that is placed in furnace wall 2 and fire door 5 uniformly, and the inwall of said furnace wall 2 is provided with the far-infrared material coating, and the far-infrared material coating can play good anti-thermal effect.
