Coating of furnace refractory linings with high-radiation materials

Thread Content

The new type of high-radiation material developed by Jinan Huimin Technology – the micro-nano high-temperature far-infrared energy-saving coating – is widely used in various industrial furnaces. The operating temperature of this high-radiation new material is: 300～1810℃ ； Suitable for various types of fuel such as gas, coal, oil, and electricity, and can reduce the heating time ； Reduce flue gas temperature ； Increase the furnace temperature and its uniformity, ensuring complete combustion of the fuel ； Improve thermal efficiency and increase work efficiency by 5%–15% ； Protect the furnace lining and extend the service life of the furnace ； Energy savings of 5% to 20%. It can be used to improve energy efficiency in various industrial furnaces, such as boilers, industrial electric furnaces, soaking furnaces, ceramic kilns, heating furnaces in the petrochemical industry, cracking furnaces, metallurgical hot air furnaces, pelletizing shaft kilns, and steel rolling heating furnaces. 　　This far-infrared coating has energy-saving properties, as identified by experts since the 1950s ； Products were introduced abroad in the 1970s ； Products were launched in the domestic market in the 1980s ； It has not been widely adopted for half a century because the construction techniques have not been properly resolved. The emissivity of this material is 0.91–0.93 ； Refractoriness greater than 1800℃ ； Adhesion level of 2 or above ； Thermal shock resistance 1200℃ ； No shedding after more than 10 repetitions at room temperature ； Particle size: 25–780 nm. Since its invention, this new material has been rapidly applied in various furnaces and kilns, such as those at Jiugang, Laigang, Handan Iron and Steel, Qingdao Iron and Steel, Changzhi, and Anshan Iron and Steel. As verified by testing departments and through actual use by users, this product features strong adhesion; it does not crack or peel off easily even when used at high temperatures, and it has a long service life. Its key technical parameters have reached international advanced levels. This post was last edited by mingjiazhao on 2007-12-20 20:36.]
