The Final Step in the High-Temperature Process: The Reheating Furnace In the reheating furnace, metals are heated and cooled in a controlled manner to adjust their physical and mechanical properties precisely. To reliably control this process, the unit must withstand extreme conditions: 🔸Chemically driven wear from residue of casting powders and scale 🔸Mechanical stresses resulting from temperature changes, abrasion, and vibration 🔸H₂ environment with increased flow velocities and larger gas volumes at the burner At the same time, the process involves high energy input and significant energy losses. To meet these requirements, Refratechnik relies on a material mix of exceptional rarity. Our proven alkali-resistant castables reliably protect against everything that degrades the refractory surface, from chemical interactions with casting compounds to infiltration and spalling. To cope with the wide range of mechanical stresses, our flexible Claybond castables are used: robust, durable, and highly resilient. Thanks to our hybrid technology, we significantly reduce repair times. Fast installation and low-risk drying accelerate furnace restart and reduce the required energy input. We are also prepared for transformation: H₂-ready as soon as hydrogen reaches your burners. Higher flame velocities and larger gas volumes are easily managed. What’s more, you’ll save on weight and energy thanks to our high-strength lightweight refractory products. From our side, nothing stands in the way of achieving your climate goals. #refractorymaterials #industrialmaintenance #steelindustry
