Abstract

The utility model discloses a heat treating furnace which comprises a furnace body. An electric heater is arranged inside the furnace body, and is fixed on the side wall of the furnace body through a bracket, the inner side wall and the top wall of the furnace body are both provided with heat insulation layers, a heat resistant steel furnace chassis is arranged on the lower portion of the furnace body, and a supporting base is arranged on the bottom face of the heat resistant steel furnace chassis. The heat treating furnace is novel in structure, the service life of the heat treating furnace is prolonged, energy is saved, a workpiece heat transfer contacting surface can be obviously improved, and temperature evenness and heat efficiency inside the heat treating furnace are improved.

Description

Heat-treatment furnace
Technical field
The utility model relates to a kind of firing equipment, particularly a kind of heat-treatment furnace.
Background technology
In machined, have many parts need heat-treat the processing of technology, make its case hardness that reaches setting, and Technology for Heating Processing need be put into workpiece in the heating furnace mostly and heats.Be with sealed hollow in the heating furnace, the heat-treatment furnace that is used to handle large-scale workpiece is to have refractory brick to assemble to form basically, and the phenomenon of local damage can appear in fire-resistant tile stove in use for some time, and in a single day local damage appears in fire-resistant tile stove, local in the stove or all in the time of setting, will not reach predetermined temperature, can waste energy so first, second need heat treated workpiece will not reach due treatment effect, at this moment heat-treatment furnace just can not continue to use, need will make again after its demolition, so neither take a lot of work, time-consuming, increased the manufacturing cost of heat treated stove again, so be necessary the structure of existing heat-treatment furnace is improved.
The utility model content
The purpose of this utility model just is to provide a kind of novel structure, and the heat-treatment furnace of long service life can effectively solve the problem of above-mentioned existence.
To achieve these goals, the technical solution adopted in the utility model is such: heat-treatment furnace of the present utility model, comprise body of heater, be provided with electric heater in the described body of heater, electric heater is fixed on sidewall of the furnace body by carriage, furnace body inside wall and roof are provided with the heat-preservation cotton layer, and the body of heater bottom is provided with the heat resisting steel furnace hearth plate, and heat resisting steel furnace hearth plate bottom surface is provided with supporting seat.
As preferably, described supporting seat is 2, and is cylindrical.
As preferably, described body of heater is assembled by refractory brick and forms.
Compared with prior art, advantage of the present utility model is: the utility model novel structure, inboard wall of furnace body is provided with the heat-preservation cotton layer, makes its heat-treatment furnace inwall occur only needing the heat-preservation cotton that it is local to be changed after the local damage, just can make annealer continue to use, prolonged the service life of heat-treatment furnace, energy savings, bottom of furnace body are provided with the heat resisting steel furnace hearth plate, accelerate the heat conduction, workpiece heat transfer contact face be can obviously improve, the temperature homogeneity and the thermal efficiency in the stove improved.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, heat-treatment furnace of the present utility model, comprise body of heater 1, be provided with electric heater 2 in the described body of heater 1, electric heater 2 is fixed on body of heater 1 sidewall by carriage, body of heater 1 madial wall and roof are provided with heat-preservation cotton layer 3, body of heater 1 bottom is provided with heat resisting steel furnace hearth plate 4, and heat resisting steel furnace hearth plate 4 bottom surfaces are provided with supporting seat 5, and described supporting seat 5 is 2, cylindrical, described body of heater 1 is assembled by refractory brick and forms.
Body of heater 1 inwall is provided with heat-preservation cotton layer 3, make its heat-treatment furnace inwall occur only needing the heat-preservation cotton that it is local to be changed after the local damage, just can make annealer continue to use, prolonged the service life of heat-treatment furnace, energy savings, body of heater 1 bottom is provided with heat resisting steel furnace hearth plate 4, accelerates the heat conduction, workpiece heat transfer contact face be can obviously improve, the temperature homogeneity and the thermal efficiency in the stove improved.
