Low thermal conductivity insulating castables to minimize heat loss of furnaces.
Lightweight insulating castables use expanded perlite and alumina bubble aggregates for low bulk density and thermal conductivity, placed between the working lining and shell to cut heat loss and shell temperature. Combined with working linings for furnace and boiler insulation sections.
