Product details
LONGKETER supplying a comprehensive range of Insulating Firebrick.Insulating Firebrick are made from high-purity refractory clays ;temperature of use ranging from 1100℃ to 1700℃ and each grade is formulated to meet specific thermal and physical requirements . For higher temperature products , their addition of alumina are graduated .Each grade is added by classified organic filler . This organic filler burns out during manufacture process to give a uniform and controlled pore structure .
Key Features for Insulating Firebrick
•Low thermal conductive , low heat storage
•Purity
•Good thermal insulation , enable the use of thin-walled constructions
•The good alumina contents confer good refractoriness
•Low iron and alkali fluxcontent contributes to their stability to reducing atmosphere
•These can be machined to special shapes , incurring fewer sections and joints
Insulating Firebrick are classified to Clay Insulating Brick,High Alumina Insulating Brick and Mullite Insulating Brick.
