Feature:
The board features with high structural strength, low deformation after sintering, fine heat-conducting property and dampproof, 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.This product is mainly used for metallurgy, building materials, furnace heat preservation, fireproof materials, etc.
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.
