To reach above-mentioned purpose, the utility model provides following technical scheme：A kind of salt bath furnace, including body of heater, crucible with
Electrode, the electrode is introduced and is embedded on crucible wall from crucible top, and the body of heater mainly by furnace shell and is arranged in furnace shell
Thermal insulation layer composition, the crucible is arranged in the inner chamber of thermal insulation layer formation and leaves between the wall of thermal insulation layer side gap, the stove
Body is stamped sealing bell with crucible top, and bell is provided with flue.
Further, the crucible bottom is provided with magnetic field agitation device.
Further, the furnace shell is welded by angle bar and steel plate.
Further, the thick asbestos boards of 10mm are provided between the furnace shell and thermal insulation layer.
Further, the gap of 50~70mm is left between the crucible side and thermal insulation layer wall.
Further, the flue is connected by pipeline with air exhauster.
The beneficial effects of the utility model are：The salt bath furnace has that firing rate is fast, the uniform, space availability ratio that heats up is high
The features such as；Solve the problems, such as that conventional slag deposits, saline solution do not flow, to heat medium uneven by magnetic field agitation technique；Adopt
Electrode is installed with the flush type method introduced from the top of refractory material, cooling jacket is eliminated, it is therefore prevented that the oxidation of electrode, it is resistance to
Fiery material uses crucible, protects the oxidation of heat treatment part；Flue is increased in stove top, is can absorb in heat treatment process
Pernicious gas；Temperature control system uses PID technologies, and temperature control is accurate, and programming rate is fast, green energy conservation.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, the utility model provides as follows
Accompanying drawing is illustrated：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As illustrated, the salt bath furnace in the utility model, including body of heater 1, crucible 2 and electrode 3, the electrode 3 is from crucible 2
Top introduces and is embedded on the side wall of crucible 2, and the body of heater 1 is main by 12 groups of furnace shell 11 and the thermal insulation layer being arranged in furnace shell 11
Be arranged in the inner chamber of the formation of thermal insulation layer 12 into, the crucible 2 and gap left between the side wall of thermal insulation layer 12, the body of heater 1 with
Sealing furnace lid 4 is stamped at the top of crucible 2, and bell 4 is provided with flue 5.Specifically, crucible 2 is used as refractory material, electricity in the present embodiment
Pole 3 introduces from the top of crucible and is installed in flush type method, eliminates cooling jacket, it is therefore prevented that the oxidation of electrode and heat treatment part
Oxidation；The bell of sealing is arranged at body of heater top, is capable of achieving to be brought rapidly up, and has flue on bell, can absorb in heat treatment process
Pernicious gas, environmental protection.
Electrode in the present embodiment is divided into main electrode and starts electrode, first electric to starting during blow-on because solid salt is non-conductive
Pole power transmission, makes a part of salt first melt using the resistance heating for starting electrode, is then turn on main electrode, electric current is sent out by fused salt
Thermal technology makees.
In the present embodiment, body of heater uses dismountable form with crucible.Specifically, furnace shell 11 is by angle bar and steel plate welding
Into, the asbestos board 13 of 10 millimeters thicks is put between furnace shell 11 and thermal insulation layer 12, there is a burner hearth in the middle of thermal insulation layer 12, one is put in burner hearth and is buried
Enter formula crucible 2, there is the gap of 50~70mm between the side of crucible 2 and hearth wall (the side wall of thermal insulation layer 12), such crucible 2 is being damaged
Exchange just can be hung out afterwards, and the service life of body of heater 1 is very long, such structure substantially can guarantee that not because stove is examined for a long time
Repair and influence production.
In the present embodiment, crucible bottom is provided with magnetic field agitation device, produced magnetic fields after energization, can follow saline solution
Ring is stirred, uniform beneficial to saline solution temperature, and the firing rate of workpiece can be improved again.
Flue in the present embodiment is located on stove top, i.e. bell, and it is connected by pipeline with air exhauster, will be produced in stove
Raw cigarette is drained with pernicious gas, environmental protection, while flue can also be heated by storage tank to it, makes full use of heat
Amount, the water of these heating is used to be heat-treated quenching and the surface clean desalination of part.
As the further improvement of such scheme, temperature control system is also included in the present embodiment, indexed using import instrument, K
Thermocouple is input into, pid algorithm, multibreak programing function.Using intelligent heating mode, automatic paragraphing heating, preceding 75% is fast at full capacity
Speed heating, back segment 25% is slowly heated using pid algorithm, reduces analog quantity to 60% control heating load, reduces heat in stove used
Property, thermocouple optimization is detected, reduce analog quantity into keeping warm mode prevents overshoot to 25%, and when temperature over-range, automatic disconnection adds
Heat, and acousto-optic indicating alarm.This kind of heating means reduce the loss of energy consumption, save the production time, and production technology is easy to adjust,
Heating overshoot is reduced, and energy consumption about reduces 3%-6%.
Finally illustrate, preferred embodiment above is only used to illustrate the technical solution of the utility model and unrestricted, to the greatest extent
Pipe is described in detail by above preferred embodiment to the utility model, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims institute to it in the form and details
The scope of restriction.
