Description

TECHNICAL FIELD [0001] The present invention relates to a method for manufacturing a high-temperature smelting furnace,

The present invention relates to a method for producing powder granules using a flame-retardant method at a high temperature, and is characterized in that it has high durability and can be used not only for decorative purposes but also for real life, and has a unique irregular crack The present invention relates to a method of manufacturing a minute tube furnace having a very high aesthetic completeness.

It is the first ceramics of the early Joseon Dynasty, which was covered with white clay on the gray or grayish black soil. It is the terminus of the court ruling ceremony. This dressing technique shows patterns and shows how the surface of the bowl is covered with white clay and transferred to white porcelain. Its shape has been transformed into a bold and rhythmic pattern based on the malformations of Koryo celadon, and there are many practical shapes with a sense of stability. In addition, special shapes such as generals, sickle disease, illicit disease, and soldiers began to appear. These features were transformed and developed from the Koryo celadon in the 15th and 16th centuries, and they were produced for about 200 years during the Joseon Dynasty. When it came to the 16th century, it became more white than the pattern, and gradually the tattoo and the surface makeup became white. However, due to the Japanese invasion and systematic problems, the warships were no longer developed and were destroyed.

On the other hand, the existing flame-retarding technique (commonly referred to as the Raku technique) uses a low-glaze glaze and then pulls the material from the kiln, which is hanging at a temperature of about 1,100 ° C, into a sieve, buries it in sawdust and produces smoke. It is a burning technique that can instantly check the change of color and texture by putting it in the cooler. The biggest problem of the existing technology is that the durability is weak because it is burned at about 1,100 ℃ by using glaze of low degree of light, so it is unsuitable for use in real life,

FIG. 1 is a process flow diagram illustrating a process for manufacturing a particulate filter using the high-temperature flame-spreading technique of the present invention.

Hereinafter, the present invention will be described in detail.

The inventor of the present invention has developed a method for manufacturing a novel powder blending machine of the present invention, and has developed a method for manufacturing a novel powder blending machine which can be used in real life due to the introduction of characteristic irregular cracks for each product and high durability.

Accordingly, the present invention provides a method of manufacturing a high temperature flame spraying particulate furnace comprising the steps of:

(1) forming and drying a sandy clay containing iron;

(2) first firing in a firewood kiln;

(3) dewatering kaolin-based clay;

(4) secondary firing at the firewood mark;

(5) sown oakwood;

(6) a third firing in a firewood kiln;

(7) removing from a firewood kiln and reducing the chaff, leaves and sawdust in a filling barrel filled with cakes; And

(8) Cooling in water.

In the step (1), the raw material used in the present invention is rough sandy clay containing iron powder.

The iron-containing coarse sandy clay of the present invention refers to a clay having a fine grain content of 50% or more and containing a sand component remarkably, or a clay falling within the range of sandy clay classified into triangular coordinates . The iron oxide-containing coarse sandy clay of the present invention preferably contains Al ₂ O ₃ and Fe ₂ O ₃ in a molar ratio of 1: 0.15 to 0.20. Due to the iron content, natural cracks are formed during the firing process to produce unique aesthetics.

The collected sandy clay is subjected to a zeolite process such as selection of zeolite, pickling, clay drying, vaginal pressing, and full process, and each process is well known to those skilled in the art.

The sandy clay that has undergone the geotope process passes through the molding step, and it works by using a spinneret, etc., and it is also possible to use a traditional tool such as a geological pit, a goat, or a salted fish. Usually, primary shaping and secondary shaping work.

The molded article may be dried by avoiding direct sunlight and may be dried by turning the article upside down or by applying heat to the bottom to make the entire section and bend section dry equally.

In the step (2), the dried material is firstly sintered. The first primary firing temperature is preferably 800 to 900 ° C.

In the step (3), the kaolin-based clay is sown in the first primary sintered material in a dumb manner.

The dumbbaking technique is a technique for manufacturing a sperm jetting device, which is made by dipping the object into the white clay water or by pouring white clay into the object.

The kaolin clay can further contain a color pigment. The color pigment means a pigment such as red, blue, yellow, or black, and it is possible to manufacture a color separator having various colors by using white clay containing a color pigment.

In the step (4), the clay is sieved with the dumbbell technique and then the secondary firing is performed. The secondary baking temperature is preferably 800 to 1,000 ° C. In the present invention, it is possible to obtain the effect of preventing the powder from falling off the article through secondary firing.

In the step (5), the secondary fired material is glazed with oak wood.

The glaze is made of mud and oak, and the mud is clay containing a large amount of soft sand or silt. The soil and oak timber may have a volume ratio of 10: 2 to 5, preferably 10: 3 to 4.

To explain the glaze manufacturing process more specifically, first, oakwood is loosened in a cylinder, water is mixed and stirred. After stirring, remove impurities, remove precipitate and take supernatant.

In the step (6), the glazed object is fired thirdly with oak wood. The third firing temperature is preferably performed at 1,220 to 1,300 ° C. According to the present invention, it is possible to produce a powder compact having a thicker whiteness on the surface of the object through the third firing.

Further, in the present invention, the step (6) may further include a fourth step of firing the pine material containing iron after the step (6).

The glazes used in this step are dirt and pine wood, which is sandy clay containing iron. The iron oxide-containing sandy clay of the present invention preferably contains Al ₂ O ₃ and Fe ₂ O ₃ in a molar ratio of 1: 0.15 to 0.20. In addition, since pine wood contains a considerable amount of iron, the powder burner manufactured by using the iron powder has natural cracks during the firing process, resulting in unique aesthetics.

The mortars and pine trees may have a volume ratio of 10: 2 to 5, and preferably 10: 3 to 4.

To explain the glaze manufacturing process more specifically, first, pine wood is poured into a barrel, water is mixed and stirred. After stirring, remove impurities, remove precipitate and take supernatant.

In this step, the glaze treated with pine wood containing iron is quenched 4 times. The fourth firing temperature is preferably 1,250 to 1,300 ° C.

The first to fourth firing of the present invention is a firewood kiln, which is used as a pure pine firewood.

In the step (7), a material which is fired at 1,250 ~ 1,300 ° C in the third firing step is taken out from the firewood kiln and placed in a barrel filled with chaff, leaves and sawdust, closed for 3 to 5 minutes, (8), the product subjected to the reduction process is immersed in water and cooled.

Through the steps of the above step (7) and step (8), irregular cracks are formed unusual in the milling. Unlike the conventional raku technique, in which heat is applied at a temperature of about 1,100 ° C., since the heat is applied at a temperature of about 1,300 ° C., the ceramics are classified as ceramics baked at the highest temperature of the ceramics. And, due to the process that must be taken out at a high temperature which is a core part of this technology, there is a high possibility of breakage, so it is necessary to use a good combination of soil to reduce the breakage rate.

The characteristic feature of this technology is that during the firing of the firewood kiln, it is taken out by a forceps at a temperature of about 1,300 ° C, and the lid is closed by putting it in a cask containing the prepared rice hulls, leaves and sawdust and sealing it for about 3 to 5 minutes. . And then cooled in water to form unexpected irregular cracks. As a result, emerald light, transparent and smooth color is formed, and a very interesting work product can be obtained.

In addition, when the temperature of the firewood kiln reached about 1,300 ° C by using a forceps after the firewood was burned with pure pine wood from the firewood kiln, the firewood was taken out and the firewood, leaves, sawdust, This is a technique for applying various kinds of smoke, and it is characterized by various natural changes every time smoke is applied according to the soil material or glaze.

On the other hand, the manufacturing method of the present invention applies the same smoke to the traditional technique, and even if the mixture of soil and clay is constant, the work is very different. Some bowls are useless, and some bowls have heavenly beauty. In addition, the bowl into the firewood kiln reaches about 1,000, but because of the reason that the bowl of the flame technique should be taken out only in front of the kanfu, there are only about 30 cups of smoke among the many bowls. Considering the works that complete the artistic value of the flame-retardant technique in such a process, but are taken apart from the process and broken or become incomplete, the work completed in one firing is only less than ten The degree of difficulty of the operation is considerable.

Hereinafter, the present invention will be described in more detail with reference to specific examples. The following examples illustrate one preferred embodiment of the present invention, and the scope of the present invention is not limited by the matters described in the following examples.

Using a spatula plate, the material was shaped into a bowl shape. The molded article was dried in shade and firstly sintered at 800 ° C. After completion of the primary sintering, the clay was sieved with a dumbbell technique. Next, a second calcination was performed at 1,000 ° C, and the material was sieved with a glaze mixed with sand clay and oak containing iron. Thereafter, the third firing was performed, and the temperature was performed at 1,300 ° C. The first firing to the third firing was performed in a firewood kiln using pure pine firewood. At a temperature of 1,300 ° C, the specimens were taken out with a specially designed forceps. The specimens were placed in a barrel containing the prepared rice hulls, leaves and sawdust, and sealed for 5 minutes. Next, the article was immersed in water and cooled.
