Construction of refractory cotton block of ceramic fiber module for thermal insulation material of annular kiln

In order to simplify and speed up the kiln construction and improve the integrity of the kiln lining, a new type of refractory lining products instead of traditional heavy refractory materials are introduced, which promotes the progress of kiln masonry technology

Ceramic fiber module is a kind of refractory insulation material commonly used in refractory insulation at present
The ceramic fiber module is designed to meet the insulation of some high-temperature industrial furnaces and some brick kilns, mainly internal insulation, Compared with the traditional unshaped thermal insulation materials, this kind of thermal insulation material has the advantages of low density, light weight, simple and convenient construction, simple training for construction workers, long service life, saving a lot of costs for customers, and simple follow-up maintenance
Even if there are problems, it can be stopped and repaired at any time, avoiding the long construction cycle of unshaped thermal insulation materials such as castables, Due to the disadvantage of high requirements for the construction environment, traditional thermal insulation materials are prone to problems if they are not well controlled
Therefore, at present, ceramic fiber module is one of the main products of furnace thermal insulation

Characteristics of ceramic fiber module:
1
High tensile strength: the aluminum silicate fiber prepared by wire coil method is long, which can improve the toughness of the fiber itself and prevent the thermal shock force in the furnace

2
Light weight: the bulk density of aluminum silicate fiber module is generally 220 kg / m3, and the bulk density of fiber cladding is 96 kg / m3 or 128 kg / m3
3
Thermal stability: the chemical properties of aluminum silicate fiber are stable, and rapid heating and cooling will not damage the fiber

4
Low thermal conductivity: the long diameter of aluminum silicate fiber is very small, which greatly reduces the heat transfer area and increases the thermal resistance

5
Long service life: the service life of aluminum silicate fiber products within the specified temperature range can reach 6 ~ 7 years
Regular repair of damaged parts is an important link

6
High economic benefits: aluminum silicate material has become the pillar of industrial furnace insulation industry because of its good economic benefits
