Advanced Insulation System
A regional commercial collaboration between Morgan and RHI Magnesita
The Thermal Ceramics business of Morgan Advanced Materials and RHI Magnesita have worked together to innovate thermal performance in steel treatment ladle applications through the development of an Advanced Insulation System.
This collaborative approach brings our expertise in thermal insulation together with RHI Magnesita's refractory expertise in molten-metal applications, to address one of the industry’s most persistent challenges: applying high-performance insulation in torpedo cars, tundishes, and ladles.
By combining Thermal Ceramics' unique dual-layer insulating backup with RHI Magnesita’s industry-proven dense refractories, the Advanced Insulation System delivers high-performance insulation without the traditional trade-offs. Its compact profile ensures that thermal efficiency is achieved without increasing total lining thickness, allowing for seamless integration into existing ladle designs and beyond.
Measurable impact – technically proven, economically relevant
The Advanced Insulation System is a customisable solution engineered to deliver five key strategic advantages:
- Enhanced safety: Lower steel shell temperatures reduce thermal strain and minimise shell deformation, enabling a longer lifetime.
- Energy optimisation: Enables lower tapping temperatures, reduced energy consumption at the ladle furnace, and shorter pre-heating cycles.
- Operational agility: Facilitates longer holding times without compromising melt integrity.
- Metallurgical quality: Ensures superior temperature consistency and stability throughout the melt.
- Maximised throughput: Creates the potential to increase ladle capacity by optimising (reducing) dense refractory permanent lining thickness.
Technical Validation, Trials and Market Readiness
The Advanced Insulation System was validated through a structured industrial trial program conducted under real steelmaking conditions. This validation focused on thermal stability, quantification of energy savings, and confirmation of operational robustness in direct comparison with a conventional ladle insulation solution.
The trial was executed as a direct comparison using newly relined steel ladles equipped with RHI Magnesita refractory products and operated under identical process conditions in the same period. Key performance indicators included steel shell temperatures, energy consumption at the ladle furnace, and temperature stability during ladle circulation. Data were collected at both the Electric Arc Furnace and Ladle Furnace, supported by defined shell temperature measurements to ensure transparency and comparability.
The results confirmed the performance benefits of the Advanced Insulation System. Electrical energy input at the ladle furnace was reduced by approximately 7-8% in specific energy consumption per ton of liquid steel, considering the pilot customer's operating conditions. In parallel, steel shell temperatures were significantly lower and more stable, with an average reduction of approximately 11% compared to the conventional insulation concept.
No negative effects were observed with respect to refractory wear, slag behaviour, or installation effort, confirming that the system can be implemented without changes to established operational practices. These results provide clear proof of concept for the Advanced Insulation System.
Building on this successful industrial validation, RHI Magnesita and Morgan have initiated an extended trial phase to confirm performance across a wider range of steel plants and operating conditions. This phase supports a structured market introduction and ensures that the Advanced Insulation System enters the market as a technically proven, industrially ready solution.
