Description
Technical field
The present invention relates to ceramic fabrication technique, more particularly to a kind of ceramic sintering method.
Background technology
Existing ceramic body product need to be formed because of the particularity of firing process, final products by high-temperature firing, burnt till
During base substrate product 3 have 10% or so contraction, and the kiln furnitures for being used for support product are non-shrinking, therefore base substrate product
3 faces contacted with kiln furnitures 4 just generate shrinks poor, produces shrinkage stress to cause product to burn till the deformation of contact surface (referring to Fig. 5
(a) and Fig. 5 (b)), become to burn till waste product.
Existing factory is the such contraction distortion of solution, by the way of being burnt in the pad of 4 upper berth mud plate of kiln furnitures 5.But because of mud plate
Low intensity, weight capacity is poor, is easily broken in sintering process.Mud plate 5 causes base substrate product 3 from the breaking part A of mud plate 5 after being broken
Deformed (referring to Fig. 6 (a) and Fig. 6 (b)), and the mud plate burnt can not be recycled.
The content of the invention
Based on this, for above-mentioned technical problem, there is provided a kind of ceramic body support kiln furnitures.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of ceramic sintering method, including:
The first kiln plate is horizontally disposed with kiln；
Multiple high temperature resistant balls are laid in first kiln plate；
Laid on the multiple high temperature resistant ball for carrying out at least two piece of even support in the bottom of ceramic body
Two kiln plates, gap is respectively provided between adjacent second kiln plate；
Ceramic body is placed in second kiln plate, makes its bottom by least two piece second kiln plate even support；
Start kiln and fire the ceramic body, 1100-1300 DEG C of firing temperature, time 6-8 hours.
This programme also includes：It is provided for carrying out spacing gear on the outside of the high temperature resistant ball in first kiln plate
Frame, its thickness is slightly below the diameter of the high temperature resistant ball.
The gap is 30mm-40mm.
Second kiln plate is four pieces, and four piece of second kiln plate is layed on the multiple high temperature resistant ball in 2 × 2 matrixes, and
Even support is in the bottom of ceramic body.
The high temperature resistant ball uses high temperature oxidation resisting aluminium ball, high-temperature resistant silicon carbide ball or the refractory ceramics of diameter 20mm
Ball.
The thickness of the gear frame is 15-18mm.
Second kiln plate is rectangle.
The gap is 30mm.
1200 DEG C of the firing temperature, 7 hours time.
During firing ceramics base substrate, the second kiln plate can make phase to the inventive method as base substrate shrinkage stress draws
To movement, the shrinkage stress of product is discharged with this, thoroughly solve the problem on deformation of high-end straight flange product, improve burning till for product
Qualification rate, also improves the quality of such product, reduces cost.

Specific embodiment
As Figure 1-4, a kind of ceramic sintering method, including:
First, the first kiln plate 110 is horizontally disposed with kiln.
2nd, multiple high temperature resistant balls 130 are laid in the first kiln plate 110.
3rd, laid on multiple high temperature resistant balls 130 for carrying out at least two pieces of even support in the bottom of ceramic body 2
Second kiln plate 120, gap is respectively provided between adjacent second kiln plate, it is ensured that the second kiln plate 120 will not be interfered when mobile and touched
Hit.
Specifically, the second kiln plate 120 is rectangle, and above-mentioned gap is 30mm-40mm.
When the shape matching of ceramic body product is special, such as strip, the contraction of its narrower side can be ignored, this
When, the second kiln plate 120 selects two pieces or three pieces.
3rd, ceramic body 2 is placed in the second kiln plate 120, its bottom is uniformly propped up by least two piece second kiln plate 120
Support.
Preferably, the second kiln plate 120 is four pieces, four piece of second kiln plate 120 is layed in multiple high temperature resistant balls in 2 × 2 matrixes
On 130, and even support is in the bottom corner of ceramic body 2.
By measuring the contraction data of the four direction of ceramic body product and kiln plate contact surface, it is determined that at high temperature its
Relative displacement can occur apart from 30mm under theory state, therefore above-mentioned gap is 30mm.
4th, kiln firing ceramics base substrate 2,1300-1400 DEG C of firing temperature, time 6-8 hours are started.
Preferably, 1200 DEG C of firing temperature, 7 hours time, efficiency high, to burn till quality good.
Spacing in order to be carried out to high temperature resistant ball 130, the inventive method is also provided in high temperature resistant in the first kiln plate 110
Ball outside carries out spacing gear frame 140, and the diameter that its thickness is slightly below high temperature resistant ball 130 (can not be less than the height of high temperature resistant ball 130
The half of degree).
Wherein, high temperature resistant ball uses high temperature oxidation resisting aluminium ball, high-temperature resistant silicon carbide ball or the refractory ceramics of diameter 20mm
Ball, the thickness for keeping off frame 140 is 15-18mm.
During firing ceramics base substrate, the second kiln plate 120 can be with the traction of base substrate shrinkage stress for the inventive method
Relatively move, the shrinkage stress of product is discharged with this, thoroughly solve the problem on deformation of high-end straight flange product, improve product
Sintering qualified rate, also improves the quality of such product, reduces cost.
