After ram-jolt ceramic powder, further, ceramic powder is sealed in silica gel tube, specifically, will
The unencapsulated one end of silica gel tube carries out encapsulation process.
Step S104, is fixed to the pressure (hydraulic) water of cold isostatic press after the silica gel tube stretching preset length after sealing
Cold isostatic compaction is carried out in cylinder；
After being sealed in silica gel tube by ceramic powder, further, the silica gel tube stretching after sealing is preset
Cold isostatic compaction is carried out in being fixed to the pressurization water vat of cold isostatic press after length.A kind of tool in the present invention
In body embodiment, step S104 may include that
Silica gel tube after described sealing is stretched preset length；
Silica gel tube after stretching is fixed in the pressurization water vat of cold isostatic press；
It is pressurized to the silica gel tube in described pressurization water vat preset pressure；
Keep described default pressure that the silica gel tube in described pressurization water vat is pressurizeed the scheduled time；
Silica gel tube in described pressurization water vat is carried out reduced pressure treatment, takes out in described pressurization water vat to facilitate
Silica gel tube.
The bending of the excellent pottery of length in order to avoid producing, first, the silica gel tube stretching after sealing is default
Length, in being embodied as, the preset length in the present invention can be 15-25mm, specifically, presets long
The length of degree can be changed according to the length of silica gel tube.Further it will be understood that the length of silica gel tube
It is adaptive with the length of the long rod pottery made.Further, the silica gel tube after stretching is fixed to cold etc.
In the pressurization water vat of static pressure machine, and it is pressurized to preset pressure to the silica gel tube in pressurization water vat.It is being embodied as
In, above-mentioned default pressure can be 150-250MPa.It is pressurized to preset pressure to the silica gel tube in pressurization water vat
After, keep presetting pressure to the silica gel tube pressurization scheduled time in pressurization water vat.When being embodied as, this makes a reservation for
Time can be the 30-60 second.After to the silica gel tube pressurization scheduled time, further, in pressurization water vat
Silica gel tube carry out reduced pressure treatment, with facilitate from pressurization water vat in take out silica gel tube.
Owing to the forming process of rod pottery long in the present invention is carried out in cold isostatic press, it is i.e. by pressurization
Realize the molding of long rod pottery, so the present invention need not add slurry in ceramic powder, eliminate
Dispensing and batch mixing process.And the proportioning of the various slurry of blending process generally requires the longer exploration time, so
Technical scheme decreases the time of early stage when making long rod pottery.
Step S105, after cold isostatic compaction, takes out described silica gel tube in described pressurization water vat；
After cold isostatic compaction in step S104, silica gel tube is taken out in pressurization water vat, with convenient
The biscuit of long rod pottery is taken out from silica gel tube.
Step S106, takes out the biscuit of long rod pottery from described silica gel tube；
After silica gel tube takes out from pressurization water vat, further, from silica gel tube, take out the element of long rod pottery
Base.
Step S107, is carried out at high temperature sintering in the biscuit of described long rod pottery is put into default V-groove
Reason, obtains long rod pottery.
After taking out the biscuit of long rod pottery from silica gel tube, further, the biscuit of long rod pottery is put into
Carry out high temperature sintering process in the V-groove preset, obtain long rod pottery.In the present invention is embodied as, step
Rapid S107 may include that
The biscuit of described long rod pottery is put in default V-groove；
With high temperature block, the biscuit of the long rod pottery in described V-groove is corrected compaction treatment；
The biscuit of the long rod pottery after correction compacting is carried out high temperature sintering process, obtains long rod pottery.
When carrying out step S107, first, the biscuit of long rod pottery is put in default V-groove, and uses
High temperature block is corrected compaction treatment to the biscuit of the long rod pottery in V-groove, further, to correction pressure
The biscuit of the long rod pottery after reality carries out high temperature sintering process, obtains long rod pottery.Long rod pottery in the present invention
Biscuit be placed on V-groove in carry out high temperature sintering process, due to the structure of V-groove, the element of long rod pottery
When base is placed on V-groove, stability is preferable, thus technical scheme to be conducive to producing qualification rate high
Long rod pottery.It addition, after being put in default V-groove by the biscuit of long rod pottery, high temperature block can be used
The biscuit of the long rod pottery in V-groove is corrected compaction treatment.As such, it is possible to will not place
The biscuit of long rod pottery is corrected compaction treatment, carries out the biscuit of long rod pottery after correction compaction treatment again
High temperature sintering processes, and can further improve the qualification rate of the long rod pottery produced.
It is shown in Figure 2, in a kind of detailed description of the invention of the present invention, after step S107, it is also possible to
