Special Refractory Coating provides a protective layer that enhances the durability and thermal efficiency of refractory linings in high-temperature environments such as furnaces and kilns. These coatings reduce wear, corrosion, and heat loss under extreme conditions. At Cera Thermal (Jiangsu Cera Thermal Technology Co., Ltd.), we develop advanced coating systems backed by decades of material expertise and engineering experience to ensure long-lasting performance.
Our range of Special Refractory Coating products is designed to meet diverse industrial needs. Options include alumina-based coatings for abrasion resistance, zircon-based coatings for superior slag and corrosion protection, and silica-based coatings for cost-effective insulation. Each formulation is engineered for specific service conditions, ensuring compatibility with various furnace atmospheres and refractory substrates. We also offer custom formulations tailored to unique chemical or thermal environments.
| Coating Type | Main Composition | Key Features | Typical Applications |
|---|---|---|---|
| Alumina-Based | High Al₂O₃ content | Excellent abrasion and thermal shock resistance | Rotary kilns, steel furnaces |
| Zircon-Based | ZrSiO₄ compounds | High corrosion and slag resistance | Glass and non-ferrous metal furnaces |
| Silica-Based | SiO₂-rich composition | Cost-effective, good thermal insulation | Ceramic kilns, boilers |
Our coatings are widely used across industries such as ceramics, non-ferrous metals, petrochemicals, and environmental systems. They enhance furnace and kiln performance, improve energy efficiency, and protect against slag penetration, oxidation, and chemical attack. These solutions help maintain stable operation and reduce maintenance downtime.
Furnaces and kilns: Improved lining durability and heat retention.
Boilers and incinerators: Enhanced corrosion and slag resistance.
Petrochemical plants: Reliable thermal protection under aggressive chemical exposure.
Our Special Refractory Coating delivers strong adhesion, abrasion resistance, and chemical stability. It helps reduce energy consumption by improving insulation and lowering maintenance frequency. With advanced R&D support, we ensure each system meets specific industrial requirements and provides consistent performance in demanding environments.
Each coating is formulated with high-purity ceramic oxides and binders capable of withstanding temperatures from 1000°C to 1800°C. Typical thickness ranges from 0.5 mm to 3 mm, providing effective thermal protection without compromising refractory integrity. These coatings are compatible with bricks, castables, and fiber modules. Application methods include brushing, spraying, or dipping. Our engineering team can provide detailed data sheets and installation guidance upon request.
