At HWI, A member of Calderys, we know that refractory performance is about more than selecting the right material. In demanding pulp and paper applications, proper installation is a critical part of achieving the expected service life and performance of a refractory lining.
During KILNCON 2026 in Green Bay, Wisconsin, HWI’s application specialist Katie Stephan highlighted this connection during her presentation on refractory installation, sharing insights into the installation practices that can have a direct impact on lining performance in pulp and paper kilns and boilers.
Material Selection Is Only the Beginning
Refractory systems are engineered to withstand challenging operating conditions, including high temperatures, thermal cycling, abrasion, chemical attack and mechanical stress. But even a properly specified refractory can underperform if it is not installed correctly.
Installation quality can influence key aspects of refractory performance, and many factors can affect the lining’s resistance to cracking, spalling, erosion and premature wear once the equipment returns to service.
The Contractor Is Part of the Refractory System
One of the most important elements of successful refractory installation is the expertise of the people doing the work. Experienced refractory contractors bring technical knowledge and hands-on craftsmanship to every installation—from interpreting installation requirements to recognizing field conditions that can affect the finished lining.
The best refractory material can only perform as designed when it is installed as designed.
That is why collaboration between refractory manufacturers, contractors, and mill personnel is so important. By working together before, during and after installation, teams can identify potential challenges, improve installation practices and help ensure the refractory system is positioned for maximum performance.
Advancing Refractory Knowledge Across the Industry
Industry forums such as KILNCON provide an important opportunity to share technical knowledge and practical experience. HWI is proud to participate in these educational discussions and connect with pulp and paper professionals, contractors, and suppliers who are focused on improving equipment reliability and refractory performance.
As refractory technology continues to evolve, the fundamentals remain just as important: the right material, the right design and the right installation.
Because ultimately, refractory performance isn’t achieved by the material alone. It takes engineering, expertise and craftsmanship working together.
