3D CFD flow simulation-driven Composite Refractory Bricks engineering for Jiugang Iron & Steel Group’s 1080 m³ hot blast stove — verified 15+ years service life.
Composite Refractory Bricks Technology Background
Composite bricks technology is a general design of refractory masonry with excellent structural stability developed on the basis of Kalukin two generations of hot blast stoves.
Multi-material Composite Refractory Bricks interlock with each other and transmit stress to form solid stable masonry, oxygen-enriched combustion-supported staged combustion, low-oxygen grading and low-nitrogen combustion, and partially controllable thermal storage (checker brick or refractory ball) premixed combustion.
Such a hot blast stove achieves rapid and uniform mixing with high-intensity reflux preheating combustion, ensuring high heat efficiency, high heat strength, and high air supply temperature.
