Rosewool Insulation Refractory Co.,Ltd.
Loading, transportation, and orderly unloading - Recently, another batch of high-quality ceramic fiber blankets from Rosewool Insulation Refractory Co., Ltd. has safely arrived at the cement plant project site. When the transport vehicles with the "Rosewool Insulation Refractory Co., Ltd." logo arrive smoothly and the neatly packaged ceramic fiber blankets begin to unload, it is not just a simple material handover, but also the official start of a trustworthy insulation and protection journey.
The core equipment of the cement production line is subjected to high temperature conditions for a long time, requiring the coordinated use of multiple insulation materials. Common insulation materials for cement plants include ceramic fiber blankets, which are used for lining kilns and high-temperature pipelines; Nano insulation board - used for efficient insulation in confined spaces; Calcium silicate board - used for hard load-bearing insulation parts; Rock wool/glass wool - used for insulation in medium and low temperature areas. Among them, ceramic fiber blankets have become the main insulation material for core high-temperature equipment such as preheaters, decomposition furnaces, and rotary kilns in cement plants due to their high temperature resistance, low thermal conductivity, flexibility, and ease of construction.
The preheater, decomposition furnace, tertiary air duct, kiln hood and other parts of the cement plant are exposed to a high temperature environment of over 1000 ℃ for a long time. Ceramic fiber blanket is an efficient insulation material designed to cope with this working condition:
The temperature of the cyclone tubes and connecting flues at each stage of the preheater can reach 700-950 ℃, and the outlet flue and kiln tail flue of the decomposition furnace can also reach 650-900 ℃. Ceramic fiber blanket, as a backing insulation layer, can effectively reduce the heat dissipation of the shell and stabilize the thermal system.
The calcination temperature inside the rotary kiln can reach over 1200 ℃. After being laid on the inner lining of the rotary kiln, the ceramic fiber blanket can form an efficient insulation layer, reduce the heat loss of the kiln body, make the temperature inside the kiln uniform and stable, and improve the quality of clinker calcination.
The third air duct belongs to the core high-temperature zone, with a temperature of 850-1000 ℃. Ceramic fiber blanket can tightly fit the curvature of the pipeline, effectively locking in thermal energy.
In the high-temperature area of the cooler, ceramic fiber blanket can form a stable insulation barrier.
Insulation materials expand greatly at high temperatures, and filling ceramic fiber blankets in expansion joints can provide insulation and cushioning.
Rosewool Insulation Refractory Co., Ltd. Ceramic Fiber Blanket is made from high-quality raw materials such as carefully selected gemstones, refined through processes such as high-temperature melting, spinning into fibers, and double-sided needle punching. The product has a temperature resistance of 1050-1430 ℃, with a zirconium type ZrO ₂ content of 15-17%, and a thermal conductivity as low as 0.045W/(m · K). Compared to ordinary products, the upgraded PLUS blanket has achieved comprehensive breakthroughs in core indicators such as tensile strength, slag ball content, and thermal conductivity - with a tensile strength of 110KPa (ordinary ≥ 34KPa), slag ball content ≤ 5% (ordinary ≤ 20%), lower thermal conductivity, and a rebound rate ≥ 85%.
The product is Class A non combustible, asbestos free, easy to construct, and can be cut and fitted to irregular parts at will. From unloading and handling to installation and construction, the lightweight and flexible characteristics greatly improve construction efficiency.
As a leading manufacturer of insulation and refractory materials for over 40 years, Rosewool Insulation Refractory Co., Ltd. has successfully served many large cement enterprises such as Huaxin Cement and Zhonglian Cement, and its products are exported to overseas cement projects such as India, Serbia, and Malaysia. We provide professional services throughout the entire process, from selection, thermal calculations to installation guidance.
