Electrolytic cell insulation ceramic fiber blanket PLUS blanket

May 15, 2026

Electrolytic cell insulation ceramic fiber blanket PLUS blanket? PLUS blanket is an upgraded version of ceramic fiber blanket developed by Rosewool Insulation Refractory Co.,Ltd. specifically for high-temperature working conditions in aluminum plant electrolytic cells. By adding 15-17% zirconia (ZrO ₂) to the formula, the classification temperature can reach 1430 ℃, and it can work stably for a long time in an environment of 1350 ℃. Its temperature resistance is nearly 200 ℃ higher than that of ordinary 1260 ℃ blankets, providing sufficient safety redundancy for extreme working conditions in electrolytic cells.

PLUS blanket is specifically designed for high temperature, long-term heating, anti shrinkage, anti dust, and anti electrolytic flue gas corrosion conditions on the side, top, busbar, and flue of electrolytic aluminum electrolytic cells. It has a much stronger performance than ordinary standard blankets and is the mainstream insulation blanket for aluminum plant electrolytic cells. Temperature resistance: 1260 ℃~1400 ℃, long-term use temperature: 1050-1150 ℃.


Ceramic fiber blanket PLUS blanket vs ordinary ceramic fiber blanket:
Lower shrinkage rate: Long term use at high temperatures results in a shrinkage rate of less than 2%, while ordinary blankets have a shrinkage rate of 3-5%. The electrolytic cell does not leak heat or crack
Higher tensile strength: reinforced fibers, not easily broken during construction pulling, resistant to electrolytic cell vibration
Corrosion resistance to flue gas: resistant to fluoride salts and alkaline flue gas, non powdering and non slagging
Lower thermal conductivity: insulation effect 15% -20% higher than ordinary blankets, significantly energy-saving
