Then place it in temperature be 400 ~ 600 DEG C and first vacuumize be passed through afterwards inert gas make its internal pressure power be maintained at 0.08 ~
13 a period of time of heat preservation zone furnace chamber of 0.15MPa；
It places it in first to vacuumize again and is passed through the cooling area furnace chamber that inert gas makes its internal pressure power be maintained at 0.1 ~ 0.15MPa afterwards
14, carrying out cooling to cooling area furnace chamber 14 makes 20 ~ 200 DEG C of its temperature.
The step of technique, is implemented by the segmented continuous heat treating furnace in embodiment one.
In two batch materials, previous batch materials 10 are placed in the environment of previous furnace chamber, latter batch materials 10 be placed in it is described before
In the environment of the corresponding latter furnace chamber of the environment of one furnace chamber；Wherein, front and back is the conveying direction of material 10.
Specifically, the segmented continuous heat treating furnace in one in conjunction with the embodiments, is specifically addressed process above.
Step 1: material is placed on material platform 21, import fire door 15 is opened, material platform 21 is pushed into preheating zone furnace chamber, is closed
Import fire door 15 is closed, while ensuring that the isolating door 41 between preheating zone furnace chamber and heating zone furnace chamber 12 is in close state, to pre-
Hot-zone furnace chamber vacuumizes until furnace chamber air pressure in preheating zone is -0.1MPa, while preheating zone cavity temperature is arranged between 200-400 DEG C
Between begin to warm up, closing vacuumizes and being passed through inert gas makes preheating zone furnace chamber internal pressure power be maintained at 0.1-0.15MPa, is setting
Determine to keep a period of time (depending on the process) under temperature and pressure.
Step 2: ensuring isolating door 41 between preheating zone furnace chamber and heating zone furnace chamber 12 and heating zone furnace chamber 12 and heat preservation
Isolating door 41 between area's furnace chamber 13 is passed through inert gas all in closed state after vacuumizing to heating zone furnace chamber 12, heating
Air pressure in area's furnace chamber 12 is suitable with preheating zone furnace chamber, and temperature in heating zone furnace chamber 12 is arranged and starts to add between 300-500 DEG C
Heat.
Step 3: directly opening isolating door 41 after the completion of the first step and second step, it will expect that platform 21 transports using conveying device
To heating zone furnace chamber 12, it is then shut off isolating door 41, the vent valve that preheating zone furnace chamber is opened after closing makes gas in the furnace chamber of preheating zone
Pressure is atmospheric pressure, opens import fire door 15, repeats the first step and carries out the preheating that feeds intake, and is kept after 12 temperature of heating zone furnace chamber is stablized
For a period of time (depending on the process).
Step 4: ensure isolating door 41 between heating zone furnace chamber 12 and heat preservation zone furnace chamber 13 and heat preservation zone furnace chamber 13 with
Isolating door 41 between cooling area furnace chamber 14 is passed through inert gas after vacuumizing to heat preservation zone furnace chamber 13 all in closed state,
Quite, setting 13 furnace temperature of heat preservation zone furnace chamber is begun to warm up between 400-600 DEG C for air pressure and heating zone furnace chamber 12.
Step 5: after the completion of third step and the 4th step, directly between unlatching heating zone furnace chamber 12 and heat preservation zone furnace chamber 13
Isolating door 41 is transported to heat preservation zone furnace chamber 13 using the material platform 21 that conveying device will heat up area's furnace chamber 12, is then shut off heating zone
Isolating door 41 between furnace chamber 12 and heat preservation zone furnace chamber 13 repeats third step after closing, 21 turns of material platform for completing preheating zone furnace chamber
Feeding intake for heating zone furnace chamber 12 and preheating zone furnace chamber is moved to, 12 temperature of heating zone furnace chamber is kept for a period of time (depending on work after stablizing
Depending on skill).
Step 6: ensure isolating door 41 between heat preservation zone furnace chamber 13 and cooling area furnace chamber 14 and outlet fire door 16 all in
Closed state, is passed through inert gas after vacuumizing to cooling area furnace chamber 14, air pressure and heat preservation zone furnace chamber 13 are suitable.
Step 7: after the completion of the 5th step and the 6th step, directly between unlatching heat preservation zone furnace chamber 13 and cooling area furnace chamber 14
The material platform 21 of heat preservation zone furnace chamber 13 is transported to cooling area furnace chamber 14 using conveying device, is then shut off heat preservation zone by isolating door 41
Isolating door 41 between furnace chamber 13 and cooling area furnace chamber 14 opens cooling device (air-cooled or water drenches cooling device) to drop after closing
Warm area furnace chamber 14 is cooled down, then repeatedly the 5th step, completes heating zone furnace chamber 12, the material platform 21 of preheating zone furnace chamber shifts respectively
To feeding intake for heat preservation zone furnace chamber 13, heating zone furnace chamber 12 and preheating zone furnace chamber.
Step 8: cooling terminates when the workpiece temperature in cooling area furnace chamber 14 is down to 20-200 DEG C, cooling area furnace is opened
14 vent valve of chamber makes furnace chamber air pressure be down to atmospheric pressure, and opening outlet fire door 16 will expect that platform 21 takes out, and completes the heat of the first batch materials
Processing.
Step 9: the 4th section of furnace temperature, which closes discharging door after restoring to room temperature, repeats the 6th step, then repeatedly the 7th step is complete
At complete third, two, the material platform of primary reformer chamber be transferred to feeding intake for the four, the three, secondary reformer chamber and preheating zone furnace chamber respectively.
The technique of the present embodiment is especially suitable for the heat treatment to the product made of non-crystalline material or nanocrystalline material.
