High-Temperature Furnace Linings up to 1,850 °C – How PCW-Based Linings Increase Precision, Efficiency and Service Life

Process temperatures up to 1,850 °C place extreme thermal, mechanical and chemical demands on furnace linings. The performance of the insulation system directly affects process stability, energy consumption and maintenance intervals.

This presentation provides practical insights into the manufacture and processing of vacuum-formed polycrystalline mullite/alumina wool (PCW) components and explains how material selection, design and installation influence long-term performance.

Typical damage patterns such as cracking, spalling and discolouration are analysed – including their root causes and effective prevention strategies are also discussed.
