PROMATON® lightweight refractory
bricks
Areas of Application
PROMATON® lightweight refractory
bricks are used in furnaces and thermal
processing plants with low mechanical
stress and without any corrosion loading.
They are particularly suitable for use in
continuously operated plants.
Examples include:
- ceramic industry plants like chamber,
bogie hearth and tunnel kilns
- anode baking furnaces
- coke ovens
- cracker and process plants in the
petrochemical industry
- combustion chamber lining
PROMACOR is suitable for high-tempera-
ture applications where low thermal con-
ductivity, low weight, high temperature
shock resistance and no fibres are requi-
red.
Examples include:
- interior insulation of laboratory and
industrial furnaces
- bogie hearth lining
- use as kiln furniture
- highly reducing furnace atmosphere at
high temperatures
- extreme chemical stress in the furnace
chamber at high temperatures
Material Description
PROMATON® lightweight refractory
bricks are produced from pure raw mate-
rials according to the casting or extrusion
process using fine burnout materials and
firing in modern furnaces. Production is
quality-proven and certified according to
ISO 9001.
PROMACOR is a high-temperature ther-
mal insulating material based on 98%
alumina for temperature applications at
up to 1700°C. PROMACOR is a fibre-free
material and does not contain any free
quartz. It is produced according to a
special sol-gel process.
