Reduction cells and pots
Custom-shaped rigid formats use the defined pot construction efficiently and keep insulation close to the required thermal boundary.
Aluminium thermal efficiency
Support temperature control from furnace to transfer.
Siltherm fits behind the refractory in furnaces, launders and transfer ladles, helping molten aluminium stay closer to its target temperature during holding and transfer.
Thermal efficiency across the processAcross the process
Follow the thermal boundary through the process.
The preferred format changes as the process moves from cells and furnaces to launders and transport ladles.
Melting and holding furnaces
Low-conductivity backup insulation helps retain heat behind the refractory and manage heat reaching the outer casing.
Launders and downstream routes
Thin rigid or flexible formats maintain an insulation path through long runs, corners, joints and supports.
Road transport ladles
Flexible and shaped formats follow curved walls and bases to support heat retention during transfer.
Equipment context
Different geometry calls for a different format.
Transport ladles need a format that follows the vessel. Large furnace faces often favour rigid or encapsulated panels.
01Road transfer ladle
Curved walls and base transitions favour flexible or shaped formats that can be fitted around the available lining envelope.
02Melting and holding furnace
Large faces and refractory interfaces favour rigid or encapsulated formats that provide thermal resistance within limited space.
Launder heat retention
Carry insulation through every bend and support.
Siltherm Panel forms a thin, clean-handling backup layer around the refractory channel. It limits heat loss while preserving casing and access space.
- Continue the thermal path through corners
- Fit around joints, supports and access points
- Work within the available casing envelope
Format selection
Match the format to the equipment.
Start with the equipment shape. Grade and thickness then follow from the operating duty.
Reduction cells and pots
Machinable rigid sections for defined pot constructions
Melting and holding furnaces
Rigid board or encapsulated panel behind refractory linings
Launders
Thin formats for straight runs, bends, joints and supports
Road transport ladles
Flexible and shaped formats for curved walls and bases
