Problems solved by technology

At present, the production of large ceramic wares in China is basically in a blank stage, mainly because the production of large wares is time-consuming and laborious, the rate of defective products is high, and the manufacturing cost is high. Therefore, the current domestic production of large ceramic wares is extremely low, most of which are below 2 meters.

Embodiment 1

[0032] Embodiment 1: the preparation of large dragon bottle:

[0033] (1) Mix the glaze with water, apply the bottom glaze to the ceramic body, and then apply the top glaze. The top glaze is sprayed 4 times. The composition of the glaze is as follows:

[0034] The bottom glaze is composed of the following raw materials: copper oxide 0.5kg, feldspar 13.39kg, Chenwan 27.97kg, cold water stone 2.4kg, glass powder 35.56kg, burnt quartz 4.39kg, glaze ash 13.39kg, stannous chloride 2.4kg and chlorine Sodium chloride 0.5kg; surface glaze is composed of the following raw materials: lead crystal material 28.9kg, burnt material 5.78kg, kiln slag 65.05kg and sodium chloride 0.27kg.

[0035] (2) Then build a mold on the surface, make a steel mold according to the shape we need, and make the steel mold into a curved cuboid in the middle according to the shape of the large dragon bottle, with a height of 0.5 meters and a width of 1 meter. The mold is made in sections. It is divided into si...

Abstract

A large Zibo kiln ceramic ware sintering technology relates to the technical field of ceramic. The technology comprises the following steps: 1, adding water to glaze, mixing, and applying the obtained mixed liquid to a ceramic base substrate; 2, building a die on a surface layer, wherein the die is a cuboid with a bent middle portion; 3, pressing 20-30mass% of carbon, 65-75mass% of silicon and 3-5mass% of clay by a press, putting the obtained substance in a kiln, and carrying out calcining sintering molding at 1650-1750DEG C to form a ware with the thickness of 12-15cm, building a cylinder in the periphery of the large molded ceramic ware, and sealing the top to obtain a saggar; and 4, carrying out radiation heating, sintering the saggar by naked fire without contact with a cylinder from 0DEG C to 300DEG C for 18h, uniformly heating from 300DEG C to 1100DEG C by adopting oxidizing flame for 36h, and heating from 1100DEG C to 1320DEG C by adopting reducing atmosphere for 20h to complete sintering. The technology prevents collapsing, cracking, kiln drawing cracking and other phenomena, and has a high yield.

Description

Technical field: [0001] The invention relates to the technical field of ceramics, in particular to a firing process for large ceramic vessels. Background technique: [0002] Since ancient times, there has been a saying that pottery making is difficult to make a large pottery. One is that it is difficult to make a blank, and the other is that it is difficult to fire. It is almost unimaginable to fire a large pottery in ancient times, and most of them end in failure. In 2011, Huang Xiuqian, a famous pottery artist in Jingdezhen, and others creatively produced the Longteng Wealthy Blue and White Dragon Cylinder. This cylinder has a diameter of 205 cm, a height of 138 cm, and a bottom diameter of 120 cm. During the five-year production process, a total of more than 40 tons were consumed. Porcelain clay, more than 5,000 times of labor, made more than 20 blanks and 10 blanks. After firing at a high temperature of more than 1,300 degrees, 3 porcelains were fired. Only one authentic...
