refractory lining

A refractory lining is a specialized, heat-resistant material installed inside furnaces, kilns, or other high-temperature equipment to protect the structural walls from extreme heat and corrosion. Made from materials like ceramic bricks or castable refractories, it insulates and maintains the integrity of the equipment, ensuring safety and efficiency during operation. Think of it as a protective "suit" that shields the machinery from intense heat, preventing damage and extending its lifespan. Proper refractory lining is essential in industries like steelmaking, cement production, and petrochemicals, where high-temperature processes are common.
