Challenges in High-Temperature Furnace Tail Sealing

In high-temperature industrial fields such as cement, metallurgy, and electricity, furnace tail sealing has always been a difficult point in insulation engineering - it must withstand the erosion of high-temperature flue gas and adapt to the thermal expansion displacement of the furnace body. Rosewool Insulation Refractory Co.,Ltd. rare earth insulation cotton is a flexible insulation material designed to solve this problem.
                                                                                 

Key Properties of Rare Earth Insulation Cotton

Rare earth insulation cotton is mainly made of composite silicates, with a thermal conductivity as low as 0.050W/(m · K) and a service temperature of over 500 ℃. It has a soft texture, can be cut arbitrarily, and can tightly fit irregular parts such as furnace tail and pipe bends. It has no loss and does not pollute the environment during construction. More importantly, it is non combustible, acid and alkali resistant, has good waterproof performance, and has a service life far exceeding traditional hard insulation materials. It is an ideal choice for furnace tail sealing and kiln head and tail insulation.
