Description
Technical field
The present invention relates to control technology field more particularly to a kind of control methods for production crystallization hafnium.
Background technology
As shown in Fig. 2, when production crystallizes hafnium, four walls place thick hafnium raw material, intermediate cloth first in the reactor of sealing
The hafnium filament of both ends connection electrode is put as female silk, iodine is added in after vacuumizing, maintains Cu Ha areas in low-temperature condition, the electricity at female silk both ends
It connects with the mains on extremely, the temperature of female silk is maintained after energization in the condition of high temperature, at this point, the iodine added in is sublimed into iodine steam, iodine molecule
Thick hafnium low-temperature space generation tetraiodide hafnium is diffused into, tetraiodide hafnium is sublimed into tetraiodide hafnium steam and is diffused into female silk high-temperature region,
Thermal dissociation generation hafnium occurs on female silk of high temperature and iodine, hafnium are deposited on female silk, it is final so that the thick hafnium raw material of low-temperature space is continuous
Be consumed, female silk of high-temperature region is thicker due to the continuous deposition of hafnium to become weight, finally obtains target product.
During production crystallizes hafnium, with the continuous deposition of hafnium, the resistance of female silk can become less and less, due to mother
The resistance of silk is ceaselessly reducing, and the electric current for flowing through female silk is caused to be incrementally increased, and eventually results in the molten of female silk and electrode
It is disconnected, so needing constantly to adjust the electric current for flowing through female silk, by manual operation, need long-term monitoring time-consuming and laborious.
Invention content
The present invention provides a kind of for producing the control method of crystallization hafnium, can automatically adjust the electric current for flowing through female silk,
It is time saving and energy saving without manually participating in.
In order to achieve the object of the present invention, used technical solution is:A kind of control method for production crystallization hafnium,
Include the following steps:
Step 1:Thick hafnium raw material is placed in four walls of the reaction vessel of sealing, the hafnium filament of intermediate arrangement both ends connection electrode is made
For female silk;
Step 2:It connects with the mains on the electrode, during production crystallizes hafnium, measures the electric current for flowing through female silk, will measure
The current value of female silk be transferred to controller;
Step 3:The current value of the female silk measured is compared controller with the load current value of female silk, and controller compares
The voltage value of power supply is adjusted according to the corresponding voltage value of record afterwards.
As the prioritization scheme of the present invention, in step 2, the current value of female silk, current divider are flowed through using current divider measurement
The current value of female silk measured is transferred to controller to handle.
As the prioritization scheme of the present invention, in step 3, it is connected on the electrode at female silk both ends using motor-generator set to adjust
Power supply voltage value.
The present invention has positive effect:1) present invention can automatically adjust the electric current for flowing through female silk, without long-term monitoring,
It is time saving and energy saving, greatly improve production efficiency;
2) present invention effectively avoids the fusing of female silk and electrode, improves the yield rate of crystallization hafnium;
3) controller of the invention is handled by the current value of female silk measured to input, realizes classification sublevel
It adjusts, control is simple and reliable.
Description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the control flow chart of the present invention;
Fig. 2 is the schematic diagram of production crystallization hafnium.
Specific embodiment
As shown in Figure 1, include the following steps the invention discloses a kind of for producing the control method of crystallization hafnium:
Step 1:Thick hafnium raw material is placed in four walls of the reaction vessel of sealing, the hafnium filament of intermediate arrangement both ends connection electrode is made
For female silk;
Step 2:It connects with the mains on the electrode, during production crystallizes hafnium, measures the electric current for flowing through female silk, will measure
The current value of female silk be transferred to controller;
Step 3:The current value of the female silk measured is compared controller with the load current value of female silk, and controller compares
The voltage value of power supply is adjusted according to the corresponding voltage value of record afterwards.
In step 2, the current value of female silk is flowed through using current divider measurement, current divider passes the current value of the female silk measured
Controller is defeated by be handled.
In step 3, using motor-generator set the voltage value of the power supply on the electrode at female silk both ends is connected to adjust.
Wherein, controller can be the control devices such as microcontroller or ARM with CPU.Controller is by the female silk measured
Current value is compared with the load current value of female silk, the load current value of female silk is had recorded in controller, and have recorded female silk
Load current value corresponding to voltage value, by adjusting the voltage value of power supply, to change the current value for flowing through female silk.
During crystallizing hafnium in production, the resistance value of female silk is constantly reduced, can be by reducing the electricity of power supply
Pressure value flows through the current value of female silk to control, and electrode and female silk is avoided to fuse, so as to achieve the purpose that stable continuous production, simultaneously
The potential error that manual operation is brought is also avoided, it is time saving and energy saving.
Particular embodiments described above has carried out the purpose of the present invention, technical solution and advantageous effect further in detail
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the guarantor of the present invention
Within the scope of shield.
