Specification for high temperature resistant insulation material of ceramic fiber blanket in cement industry

May 26, 2026

What are the specifications of high-temperature insulation materials for ceramic fiber blankets in the cement industry? The grade of industrial insulation material ceramic fiber blanket is divided into ordinary type, standard type, containing zirconium, high aluminum, high-purity ceramic fiber blanket; Ceramic fiber blanket is a material with characteristics such as white color, regular size, low thermal conductivity, low thermal capacity, and excellent tensile strength, which is very suitable for the refractory, thermal insulation, and thermal insulation needs of kilns in the cement industry. Rosewool Insulation Refractory Co.,Ltd. is committed to the research, development, production, and sales of ceramic fiber blankets. The upgraded PLUS blanket adds material and functional advantages on the basis of ceramic fiber blankets;

The ceramic fiber blanket (also known as aluminum silicate fiber blanket) used in the cement industry is mainly classified according to size (length x width x thickness) and temperature resistance level. It is a mainstream specification reference commonly used for core equipment such as preheaters, decomposition furnaces, and rotary kilns in cement plants. For high-temperature pipelines and kiln insulation in cement plants, it is recommended to choose the specifications of 128kg/m ³ density and 50mm thickness. It is recommended to use PLUS type high-strength needle punched blankets in key areas such as preheaters and decomposition furnaces to reduce maintenance frequency and improve energy efficiency.

The temperature difference in different parts of the cement production line is significant, and it is necessary to choose the appropriate temperature resistance level according to the actual working conditions.

Temperature resistance grade:   Continuous use temperature (℃)         Applicable to chemical composition characteristics of cement plant parts
Standard type (STD)             ≤ 1000 ℃ tertiary air duct,                 grate cooler medium temperature zone, factory fire isolation zone. The content of Al ₂ O ∝ is 44-45%.
High purity (HP)                    1100 ℃ -1200 ℃ preheater,             decomposition furnace shell, kiln hood lining. Aluminum oxide content is 47-49%, with low impurity content.
High alumina type (HA)       1200 ℃ -1300 ℃ rotary kiln transition zone,      kiln hood hot surface (with extremely high requirements for thermal shock resistance). The content of Al ₂ O ∝ is 52-55%, and the crystallization is more stable.
Zirconium containing (ZA)     1300 ℃ -1400 ℃ high temperature areas with severe chemical erosion,         such as the burner around the kiln head and the smoke chamber at the kiln tail. Containing 15-17% ZrO ₂, resistant to high temperature shrinkage and corrosion.
