High-temperature energy-saving thermal insulation materials recommended - Ceramic Fibre Blanket

The need for ceramic fibre blankets for casting

Casting high temperature blanket is light and soft, it is a kind of neutral high temperature resistant material without pollution to steel water, when used, it can be cut into different sizes of blocks, placed in the high temperature casting mouth, play the role of protection and blocking slag, after the high temperature of steel water, ceramic fibre blanket will have a slight softening and shrinkage, generally do a time to use.

Product characteristics of casting high temperature resistant blanket ceramic fibre blanket

Ceramic fibre blanket has low thermal conductivity, low heat capacity, excellent chemical stability, excellent thermal stability and shock resistance, excellent tensile strength, long fibre, coarse and uniform diameter, high tensile strength, high resistance to air washout, good thermal stability. Small density volume, (96/128Kg/m3); low heat capacity (heat storage); small thermal conductivity; excellent thermal and mechanical shock resistance;

 

The use of casting high temperature resistant blankets

The ceramic fibre blanket is cut into the required specifications and then placed in the intermediate frequency furnace, ladle and iron ladle. The slag insulation blanket always floats on the surface of steel and iron when the steel and iron are discharged, and plays the role of slag filtering and slag collection at the mouth of the intermediate frequency furnace and pouring ladle, meanwhile, because it covers the liquid surface of the intermediate frequency furnace, ladle and iron ladle, it plays the role of good heat insulation and preventing the splashing of steel and iron, which can guarantee the purity of the pouring and the safety of the pouring process effectively.

Which ceramic fibre blanket is suitable for casting high temperature resistant blanket?

1. To see the colour, due to the raw material in the ‘amino’ component and storage time is too long will cause the colour to turn yellow, try to purchase the colour of white ceramic fiber blanket.

2. Good product is the formation of dumping process, long fibers in the interweaving of the time is relatively close, tear resistance, good tensile strength, bad short fiber ceramic fiber blanket easy to tear, poor resilience, easy to contraction and fracture in high temperature environments. Can tear off a small piece of view fibre length.

3. Look at the cleanliness of the ceramic fibre blanket, whether it contains some brown or black slag particles, generally, good quality ceramic fibre blanket slag content <15%.
