What kind of furnace is used for ceramic firing

Ceramics are fired in pottery kilns, in which the high temperatures generated by wood fuels cause the clay to undergo a chemical reaction that leads to changes in the composition, properties, and color of the body.

The structure of the kiln largely determines the firing temperature of the pottery, and the more reasonable the structure, the higher the firing temperature, and the more solid and durable the pottery; the sealing of the kiln affects the temperature inside the kiln, and also creates an oxidizing or reducing firing atmosphere, which affects the color of the pottery. Therefore, the pottery kiln is a major indicator of the level of pottery-making craftsmanship.

The structure of the kiln is different, the kiln temperature - and the degree of sealing is also different, therefore, the kiln determines the pottery firing temperature. The more rational the structure, the higher the fire.

Expanded Information

Generally speaking, the ceramic production process consists of three basic stages: billet manufacturing, billet molding, and porcelain sintering. At the same time the composition of the ceramic production process can be divided into production technology preparation process, the basic production process, auxiliary production process and production service process according to the different roles of the production stages.

As a socialized mass production of ceramic production process, and some other industries compared to the production process, has the following characteristics:

1, the ceramic production process is a flow-type production process, continuity is low. Ceramic raw materials from one end of the factory into production, the sequence of continuous processing, and finally become a finished product, the whole process is more complex, the degree of continuity between processes is low.

2, ceramic production process mechanization, automation is low.

3, ceramic production cycle is longer. Ceramic product production cycle, refers to the raw materials into production from the beginning, through the various processes until the finished product is produced, after all the calendar time.

4, ceramic production process of auxiliary materials such as gypsum model, sagger, boron plate and other large consumption.

5, ceramic production requires the consumption of large amounts of energy, such as coal, natural gas, electricity.
