There are many types of high-temperature industrial kilns, and different types and materials of refractory materials are used for kilns with different functions. High temperature industrial kilns use refractory materials to build inner lining to protect the normal operation of high-temperature kilns. What are the common refractory materials used for the inner lining of high-temperature industrial kilns?
A reasonable lining structure of refractory materials is the foundation for stable production of high-temperature industrial kilns. Generally, commonly used refractory materials for the lining of high-temperature industrial kilns include refractory brick masonry, amorphous refractory materials, heat-insulating ceramic fiber refractory materials, etc.
1. The selection of refractory brick masonry for industrial kilns refers to the use of refractory bricks and refractory mud to build the lining, which is the most widely used form of lining construction in kilns. When selecting refractory bricks to construct the inner lining of a kiln, it is necessary to select appropriate materials and specifications of refractory bricks according to the structure of the kiln body to build the inner lining.
2. Unshaped refractory materials are currently popular lining refractory materials for industrial kilns, mainly including refractory castables, refractory spray coatings, refractory ramming materials, etc.
During the construction of refractory castables, the refractory materials can be mixed according to the requirements and poured to the parts that need to be constructed. It has good fluidity, convenient construction, shortened construction time, good use effect, wide range of use, and can also be used in parts where refractory bricks are not easy to lay.
When constructing refractory coatings, the spraying tools used can be sprayed from multiple angles and unlimited positions. High quality refractory materials are used to spray the kiln lining as the kiln lining.
There are differences in the construction methods between refractory castables and refractory spray coatings, and there are slight differences in the essential requirements for refractory materials. For example, refractory castables require good fluidity, while refractory spray coatings require low rebound rate. However, in order to better integrate the spray coating with the kiln lining, it is generally necessary to install anchors on the kiln lining during construction hours to achieve good construction results after spraying.
Refractory ramming materials are generally used in flat or relatively flat high-temperature kiln areas. After being rammed with ramming tools, the inner lining has good density, high strength, and good use effect.
Refractory casting materials, refractory spray coatings, and refractory ramming materials are different forms of amorphous refractory materials, and are also refractory materials used for lining in various industrial kilns. Due to their convenient construction, they are applied in various industrial kilns.
3. Ceramic fiber insulation material is a type of insulation material, commonly used in industrial kilns that require insulation to avoid heat loss. Ceramic fiber insulation materials include fiber blankets, fiber cotton, fiber felt, fiber boards, and other fiber materials.
According to different uses, different types of refractory materials are selected as lining for high-temperature industrial kilns to protect the kiln shell from erosion and ensure the normal operation of the high-temperature kiln, playing an important role.
