This high-temperature refractory revamping and maintenance project conducted by Ferretti focused on restoring the thermal efficiency and integrity of combustion chambers and crowns in a primary metallurgical plant.

Operating within critical plant shutdown windows, Ferretti’s specialized crews executed controlled demolition of deteriorated linings followed by the precision installation of advanced multilayer refractory systems.

Project Highlights:

• Thermal Modeling and Inspection: Comprehensive thermographic analysis to detect cold spots and structural casing stresses.
• State-of-the-Art Refractory Materials: High-alumina dense refractory bricks, castable and gunning concretes capable of enduring chemical attack and severe thermal cycling up to 1,400°C.
• Energy Efficiency: Substantial decrease in shell heat dissipation, delivering measurable fuel economy and emission cuts for the client.
