Magnesium Silicate Insulation Board is a new lightweight insulation material with low thermal conductivity, good insulation properties and heat resistance.
The Magnesium Silicate Insulation board is made of sepiolite matrix material (mainly magnesium silicate) by pulping, molding, forming and drying. Within the operating temperature range, it can be used for a long term without aging and deterioration. It is non-toxic and odorless.
The Magnesium Silicate Insulation board features with high structural strength, low deformation after sintering, fine heat-conducting property and damp-proof. Especially its physical performance is quite stable under high-temperature operation. The application of this board can promote the volume stability of the whole liner, reduce furnace surface temperature, eliminate operating force among bricks, so as to ensure furnace’s safety performance and effectively save the energy.
The shell temperature of test ladle that takes Magnesium Silicon Thermal Insulation Board as liner is much lower than that of common ladle, which averagely reduces 75℃, while the maximum temperature reduction will be about 120℃. Therefore, the board application will facilitate to eliminate the deformation of ladle shell materials, and greatly improve operation environment of ladle. The temperature drop rate of molten steel is smaller than that of common ladle, namely average 0.3~0.5℃/min. It indicates that the heat preservation of molten steel is quite great, which can not only save energy and heat losses, but also is beneficial for the constant temperature and rate during steel casting process to ensure the smooth continuous casting.
Magnesium Silicate Insulation Board is mainly used for metallurgy, building materials, furnace heat preservation, fireproof materials, etc. compared to other insulation materials, it is easy to install and cut and has no pollution to the environment, no irritation to skin and no loss during the construction.
