Product Details
Performance & Advantages:
Excellent thermal shock stability;
Superior erosion resistance;
Refractoriness typically ranges from 1580–1770°C.
Applications:
Shaped fireclay bricks for roasting furnaces are widely utilized in industries such as cement, metallurgy, lime production, glass manufacturing, and iron & steel.They are always used in furnace doors, flue duct elbows, and arch crowns. With superior thermal shock resistance, these bricks effectively buffer thermal stress, minimize cracking, and ensure stable operation in low-temperature zones, therωωωeby extending equipment service life.
