Ceramic fiber module is a new type of refractory furnace lining products, which is mainly used to simplify and speed up kiln construction and improve the integrity of the furnace lining. Its structural characteristics mainly include the following aspects:
First , Anchor nail position design
1. Location characteristics: The anchor nail of the ceramic fiber module is on the cold side of the lining (that is, the distance from the steel plate is about 50mm), which makes the anchor nail far away from the hot surface.
2. Advantages: It not only reduces the formation of thermal bridges between furnace gas and furnace wall plates, reduces the heat transfer efficiency, but also reduces the grade requirements of anchor materials, thereby helping to reduce the project cost.
Second, the overall performance is superior
1. Fiber structure: The ceramic fiber module has good integrity and low fiber thermal conductivity, which makes the overall thermal insulation effect excellent. At the same time, the fiber bulk density is small, and the impact on the load of the entire steel structure is small.
2. No binder: The module does not contain binder, which avoids the reaction with the flue gas to generate harmful gases during use, so as to effectively protect the steel plate from damage.
Third, the construction is convenient and efficient
1. Simple construction: The ceramic fiber module is easy to construct, because of its elasticity and predictable compression, there is no need to leave expansion joints during construction, which greatly simplifies the construction steps.
2. Short cycle: The module has a short construction period, and it can be put into production without an oven after the construction is completed, which effectively shortens the production cycle.
Fourth. Excellent thermal stability and thermal shock resistance
1. Thermal stability: The ceramic fiber module has excellent thermal stability and can maintain stable physical and chemical properties in a high-temperature environment.
2. Thermal shock resistance: At the same time, the module also has excellent thermal shock resistance, which can withstand rapid temperature changes and is not easy to damage.
Fifth. Environmental protection and harmlessness
1. Environmental protection of materials: The main raw materials of ceramic fiber modules are inorganic substances, which do not contain harmful substances and radioactive substances, and are harmless to the environment and human health.
2. Long life: The module has a long service life and is not easy to be damaged, which reduces the generation of waste and the cost of disposal.
Sixth. Diversified classification
1. Classification of molding methods: Ceramic fiber modules can be divided into various types such as folding blocks, slicing blocks, Pyro blocks, and vacuum forming blocks according to different molding methods. Among them, the Pyro block adopts a new molding method, and its thermal insulation effect is better than that of the first two modules.
2. Classification of temperature grades: According to the temperature grade, it can be divided into various types such as 1050 ordinary ceramic fiber modules to meet the needs of use in different temperature environments.
To sum up, ceramic fiber modules have been widely used and recognized in many industries for their excellent structural characteristics and performance.
