Problems solved by technology

[0003] At present, most saggers are integrally formed, and the frequency of use is about 70 times. When a part of the sagger is damaged, the whole sagger needs to be replaced; and in the process of firing porcelain, the heat transfer rate of the integrated sagger is relatively slow. Moreover, the traditional one-piece saggar has a heavy load on the kiln due to its heavy weight, and the production rate is reduced.
On the other hand, the traditional one-piece saggers are made of raw materials with large particles, which will cause uneven heat transfer, and in severe cases, cracks will occur on the surface of the fired porcelain, which greatly affects the yield of fired porcelain.
[0004] At present, there are various combined saggars on the market, but due to defects in the raw materials and structural design of the saggars, the heat transfer rate of the saggars is slow and uneven, which brings pressure on the firing of precision ceramics. very inconvenient

Embodiment 1

[0040] like Figure 1 to Figure 5 , Figure 8 As shown, the combined detachable high-temperature sagger of the present invention includes a plurality of first assemblies I and a plurality of second assemblies II, wherein the first assemblies I include first bumps 1, columnar bumps The strip 2 and the connecting part 3, the first bump 1 is connected to the columnar convex strip 2 through the connecting part 3, and a groove matching the connecting part 3 and the columnar convex strip 2 is provided on one side of the first bump 1 4. A first through hole 5 is set on the other side of the first bump 1, a second through hole 6 is set between the groove 4 and the first through hole 5, and a trapezoidal shape is set at the second through hole 6. The concave part 7, the width of the connecting part 3 is smaller than the diameter of the columnar convex strip 2; the second assembly II includes a second bump 8, and one side of the second bump 8 is arranged with the first assembly I The ...

Embodiment 2

[0050] like Figure 6 and Figure 7 As shown, the combined detachable high-temperature saggar of the present invention is different from Embodiment 1 in that the second assembly II is also provided with a third through hole 10, and the setting of the third through hole 10 can be Further enhance heat transfer efficiency.

[0051] The preparation method of the combined detachable high-temperature saggar comprises the following steps:

[0052] Step 1: Pulverize the leftovers of waste ceramic devices, remove iron impurities in them through a magnetic separator, and pass through a 50-100 mesh sieve to obtain basic powder;

[0053] Step 2: According to the parts by mass, 110 parts of the base powder obtained in Step 1, 20 parts of paraffin and 0.12 parts of oleic acid were mixed and stirred, and the temperature was raised to 65 ° C, and the pulp cake was obtained after natural cooling;

[0054] Step 3: raising the temperature of the slurry cake obtained in step 2 to 88°C, placing...

Embodiment 3

[0059] The structure of the combined detachable high-temperature firing sagger of this embodiment is the same as that of Embodiment 1, the difference is that its firing method is different from that of Embodiment 1, as follows:

[0060] The preparation method of the combined detachable high-temperature saggar comprises the following steps:

[0061] Step 1: Pulverize the leftovers of waste ceramic devices, remove the iron impurities through a magnetic separator, and pass through a 100-mesh sieve to obtain the basic powder;

[0062] Step 2: According to the number of parts by mass, mix and stir 100 parts of the base powder obtained in Step 1, 13.5 parts of paraffin and 0.1 part of oleic acid and heat up to 62 ° C, and naturally cool to obtain a slurry cake;

[0063] Step 3: raising the temperature of the slurry cake obtained in step 2 to 85°C, placing them in the molds of the first assembly and the second assembly respectively, and hot injection molding to obtain a green body; ...

Abstract

The invention relates to a combined detachable high-temperature sintering-bearing saggar and a preparation method and application thereof, and belongs to the technical field of appliances for ceramic sintering. The combined detachable high-temperature sintering-bearing saggar comprises a plurality of first assemblies and a plurality of second assemblies, wherein the plurality of first assemblies are mutually connected in a matched manner through grooves of the first assemblies and columns ribs and connecting portions of adjacent first assemblies; second grooves of the second assemblies are connected with the columnar ribs and connecting portions of the first assemblies in a matched manner. The sintering-bearing saggar provided by the invention has the advantages that the structure is reasonable and simplified, the heat can be effectively transferred, the heat is uniformly transferred, and the rate of finished products of sintered precision ceramic parts is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of ceramic firing utensils, in particular to a combined detachable high-temperature firing sagger and its preparation method and application. Background technique [0002] Sagger is one of the important kiln furniture for firing porcelain. It is made of refractory materials fired at high temperature. Generally, during the firing process of porcelain, in order to prevent harmful gases from causing damage to the green body or prevent cracks on the surface of the porcelain caused by uneven temperature during the direct firing process, the porcelain parts are usually placed in a sagger for firing. The use of saggers to fire porcelain can not only increase the firing output, but also increase the yield of finished products. The shape of the saggers also varies according to the fired porcelain. [0003] At present, most saggers are integrally formed, and the frequency of use is about 70 times. When a part of the ...
