High performance calcium silicates for electrolytic reduction cells

PROMASIL®-1000 are large-size, lightweight asbestos free insulating boards.

In combination with dense and lightweight refractory bricks or concrete, they are the ideal rear lining construction material. As generally known, the low thermal shock resistance of calcium silicates excludes its use on the front side. PROMASIL® materials can be produced as boards, pipe sections, segments and cut sections.

Working & processing

< #Back#

This PROMASIL® range of products can be easily worked and machined with woodworking tools.

When cutting to size, the maximum recommended workplace concentration for dust generation must be observed. We advise local dust extraction in the cutting zone.

Typical applications
