Furnaces and soaking equipment
Rigid and encapsulated formats add compact resistance behind large refractory surfaces and covers.
Application focusIS / 01
Iron, steel and process equipment
Control heat at shells, casings and process lines.
Siltherm brings compact thermal resistance behind refractory linings and around high-temperature equipment where conventional insulation takes too much space.

Process heat map
Match the insulation to each high-temperature route.
The product form follows the lining, pipe or access conditions around the equipment.
Ladles, tundish and degassers
Flexible formats follow curved walls and base transitions while preserving space for the working lining.
Process piping and hot-air routes
Preformed and flexible insulation follows steam, oil, gas and hot-air lines, including bends and changing profiles.
Retained cavities and removable systems
Flexible or pourable formats cover complex voids and equipment zones that still need practical access.
Space-efficient lining design
Control shell-side heat within the available backup space.
Compact microporous backup reduces heat flow through the refractory build-up while preserving space for the working lining.
Molten metal and process heat
High-temperature duty starts at the process boundary.
Primary refractory
The refractory provides structure, wear allowance and mechanical support.
Thin backup insulation
Rigid, encapsulated or flexible formats add resistance in limited space.
Steel shell
The protected boundary supports safer surrounding conditions and lower heat loss.
Equipment applications
Use the right format for every equipment shape.
Flat linings favour rigid formats. Curved vessels need insulation that follows the shell.
01Transfer and process ladle
Thin flexible backup follows curved walls and base transitions while retaining valuable process heat.

02Electric arc furnace
Rigid or encapsulated formats bring compact thermal resistance to large lining areas.
03Tundish and transfer path
Configured panels maintain coverage through shallow vessels, joints and local penetrations.
AluFlex in ladle linings
Retain heat around the curved ladle wall and base.
AluFlex follows the curved wall and base transition behind the refractory. Its thin aluminised construction preserves lining space and is straightforward to handle on site.
