What is the introduction of rock wool roll felt insulation material for aluminum plants?Rock wool roll felt is a roll shaped insulation material made mainly from high-quality natural rocks such as basalt and dolomite, which are melted into fibers at high temperatures and processed into fibers. Rock wool roll felt is divided into several categories based on its density and high temperature resistance; There are also veneers that combine insulation materials, which are divided into single-sided aluminum foil rock wool roll felt and double-sided aluminum foil rock wool roll felt; Low temperature pipeline or equipment insulation (temperature<600 ℃) in aluminum plants, rock wool roll felt is an economical and practical choice. Aluminum plant insulation material rock wool roll felt function introduction: 1. Excellent high temperature resistance: The zirconium containing formula can withstand temperatures up to 1430 ℃, nearly 200 ℃ higher than ordinary ceramic fiber blankets, providing sufficient safety redundancy for extreme working conditions in aluminum plants 2. Anti aluminum liquid erosion: The zirconium containing formula significantly enhances the resistance to aluminum liquid and fluoride vapor, extending the service life by more than 30% 3. Low thermal conductivity: At 600 ℃, the thermal conductivity is only 0.16-0.19W/(m · K), which has a significant energy-saving effect. The heat loss in the furnace door area can be reduced by 65% 4. Excellent thermal shock resistance: able to withstand rapid cooling and heating impacts, suitable for frequent start-up and shutdown conditions in aluminum plants 5. Fire and heat insulation of equipment: providing structural stability in high-temperature environments and extending the service life of equipment.
In the high-temperature pipeline insulation project of large-scale aluminum plants in China, the use of rock wool roll felt from Rosewool Insulation Refractory Co.,Ltd. for wrapping significantly reduces the surface temperature of the pipeline, reduces heat loss by about 30%, and saves energy costs by millions of yuan annually. At the same time, the fire resistance of rock wool roll felt effectively prevents the risk of fire around pipelines and improves overall safety.
