Among the many refractory furnace linings, the use rate of ceramic fiber modules is getting higher and higher due to its higher cost performance and energy-saving characteristics. So what are the specific reasons that make ceramic fiber modules more and more popular in the refractory market? Today SUNTHERM will take you to find out!
1. From the perspective of heat insulation effect
From the perspective of thermal insulation effect, the thermal insulation performance of the ceramic fiber module is better than that of refractory bricks and castables. The thermal conductivity in the high temperature zone is small, and it has excellent thermal insulation effect. At 1000°C, its thermal conductivity is only 15% of that of refractory clay bricks and about 38% of that of light clay bricks, second only to nano aerogel felt and nano heat insulation board;
2. From the perspective of refractoriness
From the point of view of refractoriness, the long-term use temperature of ceramic fiber modules is between 1000-1400°C due to the different raw materials, which is much higher than the maximum use temperature (500-700°C) of fibrous thermal insulation materials such as rock wool and glass wool. , Slightly lower than mullite refractory bricks and castables, but significantly better than nano aerogel felt and nano heat insulation board;
3. From an economic point of view
From an economic point of view, with the same thermal insulation effect, the cost per square meter of ceramic fiber modules is slightly lower than that of heavy refractory furnace linings, and far lower than nano-insulation materials.
In summary, in the conventional furnace insulation scheme (no friction, no strong acid-alkaline atmosphere and wind speed less than 10m/s), the thermal insulation cost performance of ceramic fiber modules is quite high compared to heavy thermal insulation materials and nano thermal insulation materials. of.
