Isolite Insulating LBK Insulating Firebrick
Manufacturer: Isolite Insulating
LBK Insulating Firebrick
Features
Hot Surface and Back-up lining insulation
LBK Series are the world’s highest level of super lightweight Insulating Firebrick. LBK Series are using for Hot Surface and Back-up lining insulation, and it has a characteristic of light weight, low thermal conductivity, low heat storage, small reheat shrinkage, high thermal stability and suitable for superior resistance to reductive atmosphere.
Typical Applications
Hot face expose and back-up lining of Annealing Furnace, Carburizing Furnace, Galvanizing Furnace, Carbon Baking Furnace, Heat treatment Furnace, Hot Stove, Clacking Furnace, Reformer, Incinerator.
