And have the control system composition of PID integrated control algorithms, it is mainly responsible for the measurement and control of humiture in stove.It needs to refer to
What is gone out is the heating wire that mode of heating used by heater 4 includes but are not limited to ceramic tube winding in the utility model, is adopted
With other mode of heatings such as radio frequency heating, microwave heating etc. the utility model protection is also belonged to the annealing furnace that hot mode is built up
In range.Meanwhile the deflector hole of the utility model opens up mode and is also not limited to be opened at fire door, it also can be by furnace body
Near middle opens up different size of deflector hole to control gas stream in the stove, and then obtains that be more advantageous to in-furnace temperature uniform
Property air-flow layout.
The course of work of the utility model annealing furnace is discussed in detail with reference to Fig. 1：
Furnace structure is mainly made of furnace wall 1 and fire door 2, and furnace wall 1 and fire door 2 are all made of stainless steel fitting thermal insulation material knot
Structure, and outer layer stainless steel is integrally molded, while also having sealing door lining 3 at fire door, it can ensure the airtight of furnace body in this way
Property, prevent vapor from penetrating into stove.Guide tank 5 is equipped in furnace body, by upper panel, lower panel, front panel, rear panel and
Right panel totally five panels composition, guide tank 5 and furnace wall 1 form current path, and heater 4 is placed in upper of furnace body, lower part, preceding
In the current path at portion and rear portion, the air-flow to flowing through access heats.Furnace body right part is equipped with circulation axial-flow wind turbine 9, simultaneously
Guide tank 5 is provided with deflector hole 6-8 close to fire door direction, and gas stream in the stove circulation path is collectively formed.Gas stream in the stove direction is from axis
Flow fan is flowed to the current path of upper of furnace body, lower part, front and rear, after being heated near the fire door at deflector hole 6-8
Into burner hearth, axis stream circulating fan 9 is flowed to by burner hearth 11 gap of material to be annealed, to realize the recycle stream of furnace gas
It is dynamic, and then improve in-furnace temperature uniformity.Simultaneously it is to be noted that guide tank 5 is located in heater 4 and material to be annealed 11
Between and be in body structure, have equal thermal effect, be more advantageous to the uniformity of in-furnace temperature.
Furnace body rear portion is equipped with sampling access 12, is measured to in-furnace temperature and humidity by temperature humidity detector 13,
And control system is fed back to, in-furnace temperature and humidity are controlled.In-furnace temperature control relies primarily on the work(of control heater 4
Rate controls in-furnace temperature, and humidity relies primarily on the humidity control loop at furnace body rear portion and controlled in stove.Gas
Humidity control loop is mainly led to by sampling wind turbine 14, fresh-air fan 15, fresh air valve 16, dehydrater 17, preheater 18 and return air
Road 19 forms.Since furnace high-temperature gas hygroscopicity is very strong, to humid control in stove mainly control stove in humidity compared with
In low level.When humidity is higher in stove needs to reduce humidity in stove, the frequency of wind turbine 14 is sampled by increase, by gas in stove
After body removes moisture after converging by sampling access and air inlet by drier 17, then preheated device 18 preheated after return to stove
In thorax, to reduce water vapour content in stove.Simultaneously under the action of fresh-air fan 15, return air amount is than sampling exhaust fan amount
Greatly, this to maintain micro-positive pressure in stove, so as to avoid the infiltration of vapor at fire door.In order to preferably maintain fresh air air inlet
The adjusting of pressure, fresh-air fan can also be changed to the air accumulator with air compressor machine, be carried out to pressure by intake valve more reliable
Adjusting.It is the control more optimized it should also be noted that using the strategy of gas circulation and external feed stream co- controlling
Strategy, certainly also can be according to humid control demand, only with one kind in gas circulation humid control or ambient humidity control.
The controllable annealing furnace of the utility model is proposed it can be seen from analysis above temperature humidity, by temperature control
System and humid control phase separation, so as to preferably control humiture, this be also currently on the market existing product institute not
Have.The control system of annealing furnace can be wet according to set annealing heating and temperature lowering curve and temperature in annealing process
The data that degree detector 13 is acquired, are adjusted the power of heater 4, and in the equal heat effect of guide tank and air-flow cyclic system
With the help of system, in-furnace temperature is made to be changed by setting curve.It is needed in annealing process according to anneal of material characteristic to not
Humidity with annealing stage is controlled.Since high-temperature gas has a stronger moisture-absorption characteristics, the utility model and main
It considers how gas humidity control in annealing furnace in relatively low range.Sampling access 12 and sampling wind turbine 14 first can acquire stove
Interior gas, and obtain height in stove by the humidity data of the acquired gas of the acquisition of temperature humidity detector 13, and according to special algorithm
The humidity data of wet body.When furnace gas humidity is higher than demand humidity, the control system of annealing furnace can increase sampling wind turbine
14 frequency, increases the circulating air flow of sampling access 12, while increasing the flow of fresh-air fan 15, and two-way air-flow converges laggard
Enter dehydrater 17 by air-flow cooling and will wherein moisture remove, dewatered air-flow returns to stove after being preheated by preheater 19
It is interior, the control to humidity in stove may be implemented by displacement.The above process have the advantages that following features and：
1, gas is collected out of stove by sampling circuit, is returned again in stove after water removal, can be achieved in replacement process
The mild control of furnace gas humidity can generate unfavorable shadow to avoid due to the acute variation of furnace gas humidity to annealing process
It rings.
2, the thermal shock for returning to gas to thermal field in stove can be reduced by preheater by returning to gas, to avoid to being moved back in stove
The influence of fiery temperature uniformity.By the way that temperature control and humid control are decoupled the independent control, it can be achieved that the two, keep away as far as possible
The two influences each other during exempting from control.
3, pass through the introducing of a small amount of fresh air during humidity regulation, it is ensured that slight positive pressure state is maintained in stove, so as to
It is penetrated into from fire door to avoid vapor.
