Description

[Detailed Description of the Invention] As a method for firing porcelain tile bodies, stacked porcelain tile bodies are packed in a sagger in a vertical state, and the porcelain tile blank is fired together with the sagger. The law is
Although this method is considered to be a known technique, the firing deformation of the porcelain tile body is significant and the yield is poor, so flat firing and skewering are still generally used despite the poor firing effect.

In such cases, research is usually conducted to improve the vertical shaft method, but no significant results have been reported so far.

However, the firing of the porcelain tile body and the streamlining of the processes associated with this firing cannot be achieved without the vertical shaft method.

The present invention was invented based on the above-mentioned situational judgment, and although a gap usually occurs between a large number of porcelain tile bodies and the side surface of a sagger pot, the most desirable ideal example is: The feature is that the porcelain tile element at the end that contacts this gap is replaced with a fireproof plate that does not easily deform.

The magnetic tile body has the characteristic of softening during sintering in the firing process, and therefore it was thought that a vertical shaft would be inappropriate.However, in the present invention, in order to prevent the porcelain tile body from softening and deforming, By supporting the porcelain tile bodies packed inside the sagger pot with a fireproof board that does not easily deform, we succeeded in preventing deformation defects. It also made it possible to streamline it to the same level as quality tiles.

If the technical idea of the present invention is disclosed according to its embodiments, T
is a porcelain tile body, S is a sagger, F is a fireproof plate that does not deform easily, and if there is no fireproof plate F that does not easily deform, the sagger S is as illustrated in Figure 1a. When the porcelain tile bodies T stacked inside each other are packed in a vertical shape, a gap 1 is created at the left end, and as shown in Figure 1, the porcelain tile bodies T stacked in large numbers are in a shogi-like state. Therefore, the gravity of the porcelain tile body T is broken down as shown by the arrow, and when this is fired, the porcelain tile body is deformed into a curved shape as shown in FIG. 1C.

In order to prevent this softening and deformation, as shown in FIG. 2, a fireproof plate F that does not easily deform is placed on the left end of the clustered porcelain tile bodies T.

Another embodiment is explained in FIG. 3, and in this way,
As shown in FIG. 4, when the porcelain tile bodies T are in a stacked state before being packed in boxes, fireproof plates F that do not easily deform are already interposed on the upper and lower ends (state [I]), and the openings are Stand up the sagger S so that it is facing sideways, and push the porcelain tile body T in the state [I] into the sagger S at once together with the fireproof plate F that does not easily deform (state (II)), When this is turned over so that the opening of the sagger S is facing up, it becomes the state shown in [■].Even if this is fired using the vertical shaft method like ceramic tiles, the defect rate is small. Since it is made of fabric, if the automatic packing method shown in Figure 4 is used, the bottom porcelain tile body T will rub against the sagger pot S and be damaged; This drawback was also resolved by adding a fireproof plate F that does not require fireproofing.

When implementing the method of the present invention in a factory that also produces ceramic tiles, it is convenient to use unglazed ceramic tiles as the fireproof plate F that does not easily deform.
