Abstract
The invention discloses self-control and combining sleeving method to improve nitriding quality and atmosphere of nitriding furnace, which is characterized by the following: 1. extracting vacuum pulse nitriding furnace into vacuum periodically; aerating ammonia; 2. controlling the environment through hydrogen probe automatically to control the nitriding element precisely; 3. adopting vacuum pulse nitriding furnace to replace well-typed nitriding furnace; simplifying the loading course; detaching easily to combine the self-manufacturing line.
Description
Technical field
This box type vacuum pulse nitriding furnace belongs to nitriding furnace and vacuum oven field.
Background technology
1, China's nitriding furnace is generally well formula nitriding furnace at present.
2, China's nitriding furnace carries out nitriding treatment for feeding the ammonia of constant to workpiece at present.
3, the atmosphere of China's nitriding furnace can't be controlled in real time at present, only decomposes instrument with ammonia furnace atmosphere is monitored generally.
In order to solve above-mentioned technical barrier, we have developed vacuum pulse nitriding furnace, make China's nitrogenize heat treatment furnace technology obtain breakthrough.
Summary of the invention
1, be designed to box nitriding furnace, the loading and unloading material is convenient, one-tenth automatic production line capable of being combined.
2, use the vacuum pulse nitrogenize, improved the quality of nitrogenize part, shortened the time of nitriding treatment.
3, use the hydrogen probe that nitriding atmosphere is controlled in real time, make it to form the hierarchy of control of closed loop.Not only improve the quality of item for disposal, and reached the importance of technology.
Description of drawings
1, external cooler: form by blower fan, pneumatic insulated door, electric butterfly valve etc.
2, interior device for cooling: by water-cooled machine, big flow fan, compositions such as heat exchanger.
3, vacuum pump group: form by lobe pump, slide valve pump, Vacuum connector.
4, high temperature butterfly valve: be corrosion-resistant, resistant to elevated temperatures Pneumatic vacuum butterfly valve.
5, waste gas burner: constitute by pyrosphere, automatic ignitor, the burner of igniting, drain tap etc.
6, vacuum measurement element: form by vacuumometer, vacuum probe etc., be used to control the vacuum tightness in the stove.
7, body of heater assembly: contain flue, lagging material, heating unit and part and be installed in parts on the body of heater.
8, fire door assembly
9, housing: all electric controling elements of interior dress and power supply etc.
10, agitator motor: be used for furnace atmosphere is stirred, make furnace atmosphere, heat more even.
11, hydrogen probe
Embodiment
1, the Qianmen is opened, pack in the stove with dolly dress workpiece.
2, shut the Qianmen.
3, start the vacuum unit, open the vacuum butterfly valve on the vacuum-lines, flue is vacuumized, carry out vacuum exhaust, to the certain vacuum degree.
4, charge into high pure nitrogen, and connect heating unit workpiece is heated.
5, after temperature arrives design temperature in the flue, open the low discharge ammonia gas solenoid valve, in stove, feed ammonia.Simultaneously light the Waste gas outlet pyrosphere automatically, open the exhaust gas emission magnetic valve,, open the exhaust gas emission magnetic valve, by the Waste gas outlet pyrosphere ammonia is decomposed the waste gas of discharging and fully burn by the Waste gas outlet pyrosphere.
6, behind the arrival nitriding temperature, carry out the pulse nitriding, vacuum pump is vented to Xmbar → big flow ammonia and presses again → and fresh ammonia cracking is vented to Xmbar to workpiece nitriding treatment → vacuum pump ... so carry out periodic pulse nitriding, can realize 1. the pore part being realized high-quality nitriding treatment; 2. improve loading density, increase treatment capacity; 3. and shorten the treatment time, increase work efficiency.
7, carry out in the nitriding treatment process in the ammonia decomposition, control furnace atmosphere in real time, thereby guarantee that workpiece is carrying out nitriding treatment in relative constant atmosphere, improve the workpiece quality, reach technology and reappear with the hydrogen probe.
8, by external cooler furnace temperature is carried out controlled cooling, realize some special process.
9, stop heating, nitrogen → opening the interior device for cooling of inner cool tube road valve → startups cools off → is cooled to design temperature fast to workpiece to close gas inlet-outlet magnetic valve → be evacuated to Ymba → charge into.
10, being evacuated to Xmbar → air presses again.
11, open fire door, workpiece is pulled out with dolly.
Claims (3)
1, one of feature of this equipment is the vacuum nitriding stove of box design.
2, two of the feature of this equipment is vacuum pulse nitriding type nitriding furnace.
3, three of the feature of this equipment for controlling in real time the nitriding atmosphere in the stove with the hydrogen probe.
