DESCRIPTION

High alumina fireclays & High alumina refractory castable:
Refractory castable is unshaped refractory with compounded of good quality lightweight aggregate.
It is suitable to each kind of kiln stove inside lining thermal insulation layer, floats a glass kiln stove
smoke seal to pour the material.
CHARACTERISTIC:
Low thermal conductivity, excellent thermal insulation, low liner shrinkage.
Good integrity with furnace lining, long service life, easy operation, could be shaped freely.
Refractory castable allow direct contact of fire, suitable for various atmosphere.
APPLICATION:
Furnaces of metallurgy industry, heat treatment furnace
Furnace of incineration of garbage, recirculation fluidized bed furnace
Furnaces of chemical industry and construction industry
type clay bonded cement bonded low cement bonded phosphate bonded soluble glass bonded
