Glowing furnace is the stove heated before workpiece quenching.Quenching is workpiece to be put into the quenching temperature that critical point or more is heated in stove
It is same when spending and being kept for one section, then workpiece is promptly taken out input out of stove and quenched in liquid（Oil or water）Quenching.The heat source of stove
It can be measured with thermocouple with electricity consumption and fuel, temperature.The stove of electricity consumption and gas, liquid fuel, can be automatic with instrument
To control and adjust temperature.
The structure that existing glowing furnace generally uses is that entire furnace body is enclosed in a steel structure frame.Quenching bath is located at stove
Under, the center of heating furnace is 1.2 meters eccentric relative to quenching bath, first to be hung material bundle in quenching bath using electric hoist.Then
It moves under stove, then uses chain sling（It is driven with elevator）The certain altitude in stove is moved to, until elevator automatically powers off.Promoting speed is
0.4 meter per second.Decrease speed is 0.4 ~ 0.6 meter per second when quenching.It, can single carry out quenching treatment for large-scale extruded product.
On furnace body framework, the hydraulic cylinder equipped with fire door lifting, translation.Fire door itself is equipped with asbestos seal device.Heat room and insulating layer
Between, it is 250 millimeters of annular passage to have width, and device heating element wherein.It is used between the heating room of stove and heating element
Thin plate is isolated.For assembling on stove lower platform, power of motor is 70 kilowatts.Between the heated room of air of feeding and heating element
Channel enter heating room, form the closed system of hot wind forced circulation.After the completion of heating process, oven door opening, furnace charge is straight
It connects and is put into quenching bath.Glowing furnace is divided into five bringing-up sections, and every section can be transformed into star-like connection by triangle connection.With five electricity
Electronic potentiometer automatically adjusts and records temperature.Main problem existing for existing glowing furnace is that 1) fire door airtight performance is bad,
Cause the temperature equalization in glowing furnace poor, influences quenching effect.
Invention content：
The purpose of the present invention is providing a kind of upright quenching furnace in view of the above problems, fire door can not only be preferably realized
Sealing, in-furnace temperature is harmonious more preferable, and the time of stove door switch and locking is faster, and required time is shorter, can effectively carry
High quenching effect.
Above-mentioned purpose is realized by following technical scheme：
Upright quenching furnace, including furnace body, the furnace body the inside are provided with heating room, are provided with quenching bath below the furnace body, institute
The heating ceiling portion stated is provided with bell, and the bottom of the heating room is provided with fire door, and the heating room lower part is connected by air duct
Ventilation blower, the furnace body the inside are provided with hoist engine, are provided with fire door track below the fire door, the fire door both sides are set respectively
It is equipped with two slider bars that can be slided in the fire door track, the both ends of the slider bar described in every extend outwardly connection respectively
One straight-arm, each straight-arm are installed below a hydraulic cylinder, asbestos are provided between the fire door and the furnace body
Sealing, fire door bottom connecting rod.
The upright quenching furnace, the heating room include furnace outer wall and furnace internal-lining, the furnace outer wall and the encephalic
Heating element and refractory fiber floor are provided between courage, the heating element is close to the stove inner wall setting, and the fire resisting is fine
Dimension layer is close to the furnace outer wall setting.
The upright quenching furnace, heating room the inside are provided with thermocouple.
The upright quenching furnace, the heating room are divided into 4-6 section, and each section is provided with independent heating unit
Part and thermocouple.
The upright quenching furnace, the pull rod use electronic tie rod.
Advantageous effect：
The fire door of the present invention is held out against using hydraulic cylinder, when needing to open fire door, shrinks hydraulic cylinder so that fire door declines
Into track, fire door is pulled open by electronic tie rod and carries out charging or discharging, after fastening fire door, in the thrust of hydraulic cylinder
Under, oven door sealing is relatively reliable, and in-furnace temperature is harmonious more preferable, and the time of stove door switch and locking is faster, required time
It is shorter, quenching effect can be effectively improved.
The present invention is provided with refractory fiber floor, good heat insulating.
The heating room of the present invention is divided into multiple sections, convenient for needing the workpiece of stage-hardening to use.
