Description
Technical field
The present invention relates to ceramic fabrication technique more particularly to a kind of ceramic sintering methods.
Background technique
Because of the particularity of firing process, final products need to fire by high temperature, be burnt into existing ceramic body product
Green body product 3 has 10% or so contraction in the process, and the kiln furnitures for being used to support product are non-shrinking, therefore green body product
3 faces contacted with kiln furnitures 4 just produce shrink it is poor, generate shrinkage stress cause product be burnt into contact surface deformation (referring to Fig. 5
(a) and Fig. 5 (b)), become be burnt into waste product.
Existing factory is to solve such contraction distortion, using in such a way that 4 upper berth mud plate 5 of kiln furnitures pad is burnt.But because of mud plate
Intensity is low, and load-bearing capacity is poor, is easily broken in sintering process.Mud plate 5 causes green body product 3 from 5 breaking part A of mud plate after being broken
It deforms (referring to Fig. 6 (a) and Fig. 6 (b)), and the mud plate burnt cannot recycle.
Summary of the invention
Based on this, in view of the above technical problems, a kind of ceramic body support kiln furnitures are provided.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
A kind of ceramic sintering method, comprising:
The first kiln plate is horizontally disposed in kiln；
Multiple high temperature resistant balls are laid in first kiln plate；
It is laid on the multiple high temperature resistant ball for carrying out at least two pieces of even support the in the bottom of ceramic body
Two kiln plates all have gap between adjacent second kiln plate；
Ceramic body is placed in second kiln plate, makes its bottom by least two piece of second kiln plate even support；
The starting kiln firing ceramic body, 1100-1300 DEG C of firing temperature, time 6-8 hour.
This programme further include: the gear for being limited on the outside of the high temperature resistant ball is set in first kiln plate
Frame, thickness are 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.
It is described gear frame with a thickness of 15-18mm.
Second kiln plate is rectangle.
The gap is 30mm.
1200 DEG C of the firing temperature, the time 7 hours.
For the method for the present invention during firing ceramics green body, the second kiln plate can make phase as green body shrinkage stress is drawn
To movement, the shrinkage stress of product is discharged with this, is thoroughly solved the problem on deformation of high-end straight flange product, is improved the firing of product
Qualification rate also improves the quality of such product, reduces costs.

Specific embodiment
As shown in Figs 1-4, a kind of ceramic sintering method, comprising:
One, the first kiln plate 110 is horizontally disposed in kiln.
Two, multiple high temperature resistant balls 130 are laid in the first kiln plate 110.
Three, it is 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 all has gap between adjacent second kiln plate, it is ensured that the second kiln plate 120 will not interfere with each other when moving touches
It hits.
Specifically, the second kiln plate 120 is rectangle, and above-mentioned gap is 30mm-40mm.
When the shape of ceramic body product is more special, the contraction of such as strip, relatively narrow side be can be ignored, this
When, the second kiln plate 120 selects two pieces or three pieces.
Three, ceramic body 2 is placed in the second kiln plate 120, props up its bottom uniformly by least two piece of 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 four corners of ceramic body 2.
By measurement ceramic body product and kiln plate contact surface four direction contraction data, determine at high temperature its
Relative displacement distance 30mm can occur under theory state, therefore above-mentioned gap is 30mm.
Four, starting kiln firing ceramics green body 2,1300-1400 DEG C of firing temperature, time 6-8 hour.
It is the time 7 hours, high-efficient, firing is high-quality preferably, 1200 DEG C of firing temperature.
In order to limit to high temperature resistant ball 130, the method for the present invention is arranged also in the first kiln plate 110 in high temperature resistant
The gear frame 140 limited on the outside of ball, the diameter that thickness is slightly below high temperature resistant ball 130 (can not be lower 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, gear frame 140 with a thickness of 15-18mm.
The method of the present invention during firing ceramics green body, the second kiln plate 120 can with green body shrinkage stress traction and
It relatively moves, 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 costs.
