Application functions of ceramic fiber bulk

Release Time: 2025-08-29

The adaptability and functionality of insulation refractory materials directly affect equipment operating efficiency, engineering safety, and energy consumption in industrial high-temperature operations and residential heat supply scenarios. As a local enterprise with more than ten years of deep cultivation in the field of thermal insulation and refractory, Rosewool Insulation Refractory Co.,Ltd. has launched ceramic fiber bulk products. With flexible application forms and excellent performance advantages, it has become a "thermal insulation and refractory weapon" in multiple fields such as metallurgy, chemical engineering, construction, and heat, providing precise solutions to temperature management problems in different scenarios.

The core application function of ceramic fiber bulk is efficient insulation and energy consumption control. Compared to traditional block insulation materials, its loose fiber structure can tightly fill irregular gaps in equipment and pipelines, forming a complete sealed insulation layer and effectively blocking heat conduction. The thermal conductivity of the product is as low as 0.03W/(m · K), and it can still maintain stable insulation performance in high temperature environments. A steel plant in Henan Province once faced the problem of excessive heat loss in the converter flue. After using Rosewool ceramic fiber bulk filling to fill the flue interlayer, the surface temperature of the flue decreased from 180 ℃ to 55 ℃, the heat loss rate decreased by 72%, and the monthly natural gas consumption cost was saved by more than 180000 yuan. In the field of winter centralized heating, this product also performs well. A heating company in Zhengzhou used it to fill the grooves of thermal pipelines, reducing the heat loss of pipelines by 40% compared to traditional insulation materials. This not only reduces heating energy consumption, but also ensures that the temperature in residents' homes remains stable and meets the standard.

Excellent high temperature resistance and fire-resistant protection capabilities make ceramic fiber bulk stand out in extreme high temperature scenarios. Its maximum operating temperature can reach 1400 ℃, and it does not soften or burn in high temperature environments, effectively blocking flames and high-temperature media erosion. In the insulation renovation project of a reaction kettle in a chemical enterprise in Henan, the original insulation material frequently experienced local carbonization and detachment due to insufficient temperature resistance, posing a great safety hazard. The Rosewool technical team has customized a ceramic fiber bulk filling solution for this situation, which is solidified and formed with a special adhesive. The resulting insulation and refractory layer not only withstands the working temperature of the reaction kettle at 1200 ℃, but also provides flame retardant protection in case of sudden overheating of the equipment. It has been running stably for 3 years without any safety issues. In addition, in the field of building fire prevention, this product can be used as a filling material for firewalls and fireproof ceilings. It does not release toxic gases when exposed to fire and complies with the national GB 8624-2012 A-level non combustible material standard, laying a solid defense line for building fire safety.

The flexible adaptation to irregular structures has broadened the application boundaries of ceramic fiber bulk. Industrial equipment and engineering structures come in various forms, such as irregular pipelines, complex furnaces, and gaps in equipment shells. Traditional molded insulation materials are difficult to adhere to, and can easily form insulation blind spots. Ceramic fiber bulk can be adapted to various irregular spaces through manual filling, mechanical spraying, and other methods according to on-site requirements. In the furnace insulation project of a garbage incineration power plant in Zhengzhou, there are a large number of pipeline interfaces and protruding structures on the inner wall of the furnace. Rosewool technicians use the "layered filling+local compaction" process to accurately fill ceramic fiber bulk into each gap, forming a seamless insulation layer, effectively reducing furnace heat loss, improving incineration efficiency, and reducing the impact of high temperature on the surrounding environment of the equipment outer wall. In the civilian field, this product can also be used for insulation and repair of roofs and walls of ancient buildings. Its loose property avoids damage to the original structure of ancient buildings, balancing insulation effect and cultural relic protection needs.

As one of the core products of Rosewool, the quality and service of ceramic fiber bulk have always been deeply linked to the company's concept of "quality first, customer first". The company controls the quality of raw materials from the source, selects high-purity alumina, silica and other raw materials, and produces them through fully automatic air flow fiber forming technology to ensure that each batch of products has consistent fiber uniformity and temperature resistance. Before leaving the factory, the product must undergo 15 strict inspections, including high-temperature endurance performance testing, thermal conductivity testing, and slag ball content testing, to prevent unqualified products from entering the market. At the same time, for different application scenarios of customers, the company's professional technical team will provide a full process service of "on-site survey - scheme design - construction guidance - after-sales tracking", such as customizing high-temperature kiln filling schemes for metallurgical enterprises, optimizing pipeline trench filling processes for thermal companies, and ensuring maximum product functionality. Relying on the advantages of Zhengzhou's transportation hub, the company has established a warehousing and logistics network covering Henan and surrounding provinces, which can achieve 24-hour order response and 48 hour home delivery, ensuring efficient progress of customer projects.

With the promotion of the "dual carbon" target and industrial green upgrading, the demand for energy-saving, safety, and adaptability of insulation refractory materials continues to increase. Rosewool Ceramic Fiber Bulk Products, with versatile application functions and stable and reliable performance quality, not only reduce energy consumption and ensure safety for customers, but also contribute to the green and sustainable development of the industry. In the future, the company will continue to deepen its technological research and development, optimize product performance, and launch more insulation and fire-resistant solutions that meet market demand, making ceramic fiber bulk a "reliable partner" for temperature management in more fields, and building an efficient and safe "temperature protection barrier" for industrial production and livelihood security.
