Description
Technical field
The present invention relates to the field of ceramic post sintering, particularly relate to the solid or empty of a kind of aluminum oxide material or zirconium oxide material
The sintering process of the long mandrel rod of heart pottery.
Background technology
In order to ensure mandrel rod product sintering after linearity require, prior art mainly use corundum flat board lie low sintering or
Person plays the mode sintering to ensure product linearity at below 0.4mm；Flat board carries product sintering, mainly utilizes corundum to put down
The flatness of plate ensures the linearity of product；The sintering that plays mainly utilizes the axis of the center of gravity vertical line of product and product one
Individual direction ensures the linearity of product after sintering.
The main problem of the sintering that lies low:
1), requiring high to the corundum flat board of carrying, the planarity requirements of itself is at below 0.2mm；
2), also high to the durability requirements of corundum flat board, the universal durability of existing domestic flat board was less than one month, to enterprise
For sintering cost high；
3), lie low sintering due to the area shared by cushion block to be deducted, the limited amount of every piece of flat board sintered products in fact, cause
The waste of resource, the raising of cost.
The made load bearing board of domestic corundum-mullite, due to the constraint of its formula and production technology, service life is not
Height, with regard to bending after using twenty or thirty time, thus is also bending after causing product sintering.
Content of the invention
The technical problem that present invention mainly solves is to provide a kind of pottery mandrel rod sintering process, solves aluminum oxide and oxygen
Change the phenomenon that the made long mandrel rod class product of zircon ceramic bends in sintering process.
For solving above-mentioned technical problem, one aspect of the present invention is: provide a kind of pottery mandrel rod sintering
Technique, uses corundum sagger and bottom bearing plate, including step in detail below:
Granule dust on a, cleaning corundum sagger and bottom bearing plate；
B, the corundum sagger side after cleaning is put on the operational platform, then be buckled in bottom bearing plate bottom corundum sagger；
C, inside corundum sagger first layer overlay mandrel rod product, all come to bottom bearing plate, mandrel rod bottom every mandrel rod product
Requiring that gap is well-balanced between the root of product and root, left and right sides gap is uniform；
D, with previous step c, sequence the mandrel rod product of every layer successively, until being discharged to corundum sagger top；
E, firmly grasp corundum sagger both sides with two, left and right hand, up overturn 90 degree together with bottom bearing plate so that mandrel rod
Product stands on the bearing plate of bottom；
F, will upset after mandrel rod product be together carried in sintering furnace push pedal together with corundum sagger and bottom bearing plate, put
After safe, jiggle mandrel rod product with palm so that each mandrel rod product all can fall on the bearing plate of bottom naturally, check
And correct product tilt phenomenon.
In a preferred embodiment of the present invention, described mandrel rod product uses the reality of aluminum oxide material or zirconium oxide material
The heart or the long mandrel rod of hollow ceramic.
In a preferred embodiment of the present invention, the length of described mandrel rod product at below 120mm, diameter 13mm with
On.
The invention has the beneficial effects as follows: the ceramic mandrel rod sintering process of the present invention, the existing sintering that lies low is become vertical
Standing and sintering, have preferable effect after on-site verification, the qualification rate of product linearity can be improved by original about 80%
It to 98%, and is greatly improved sintering production capacity, reduce single with the sintering energy consumption of product, thus reduce the production of enterprise
Cost.
Brief description
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, required in embodiment being described below make
Accompanying drawing be briefly described, it should be apparent that, below describe in accompanying drawing be only some embodiments of the present invention, for
From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, can also be obtained other according to these accompanying drawings
Accompanying drawing, wherein:
Fig. 1 is the structural representation that in the present invention, mandrel rod product puts into corundum sagger；
Fig. 2 is the structural representation after Fig. 1 overturns；
Being labeled as in accompanying drawing: the 1st, corundum sagger, the 2nd, bottom bearing plate, the 3rd, mandrel rod product.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of not making creative work, broadly falls into the model of present invention protection
Enclose.
As depicted in figs. 1 and 2, the embodiment of the present invention includes:
A kind of pottery mandrel rod sintering process, uses corundum sagger 1 and bottom bearing plate 2, including step in detail below:
Granule dust on a, cleaning corundum sagger 1 and bottom bearing plate 2；
B, corundum sagger 1 side after cleaning is put on the operational platform, then be buckled in bottom bearing plate 2 bottom corundum sagger；
C, inside corundum sagger 1 first layer overlay mandrel rod product 3, all come to bottom bearing plate 2 bottom every mandrel rod product 3,
Requiring that gap is well-balanced between the root of mandrel rod product 3 and root, left and right sides gap is uniform；
D, with previous step c, sequence the mandrel rod product 3 of every layer successively, until being discharged to corundum sagger 1 top；
E, firmly grasp corundum sagger 1 both sides with two, left and right hand, up overturn 90 degree together with bottom bearing plate 2 so that axle
Rod product 3 stands on the bearing plate of bottom；
F, will upset after mandrel rod product 3 be together carried in sintering furnace push pedal together with corundum sagger 1 and bottom bearing plate 2,
Put safe after, jiggle mandrel rod product 3 with palm so that each mandrel rod product 3 all can fall naturally at bottom bearing plate 2
On, check and correct product tilt phenomenon.
In above-mentioned, described mandrel rod product uses the solid or hollow ceramic major axis of aluminum oxide material or zirconium oxide material
Rod.Wherein, the length of described mandrel rod product is at below 120mm, and diameter is at more than 13mm.
Principle: ensure good linearity after wanting long mandrel rod class product sintering, it is necessary that produce in sintering process
The center of gravity vertical line of product and product axis are in same direction, so in sintering process, ceramic green embryo through binder removal, softening,
Just will not flexural deformation after the processes such as crystallization, one-tenth porcelain.
In sum, the ceramic mandrel rod sintering process of the present invention, being become hanging down from the existing sintering that lies low is erected sintering, warp
Having preferable effect after on-site verification, the qualification rate of product linearity can be brought up to 98% by original about 80%, and
It is greatly improved sintering production capacity, reduce single with the sintering energy consumption of product, thus reduce the production cost of enterprise.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other related technology necks
Territory, all in like manner includes in the scope of patent protection of the present invention.
