Advantages of Jianhong Fire Clay Bricks
- Thermal Shock Resistance: Our specific clay blend ensures bricks do not crack under rapid temperature changes (water cooling cycles > 20 times).
- Acid Erosion Resistance: The acidic nature of the material makes it impervious to acidic slag and gases.
- Dimensional Accuracy: We use high-tonnage friction presses to ensure size tolerance within ±1.5mm, reducing mortar usage and installation time.
Industrial Applications of Jianhong Fire Clay Bricks
Iron & Steel Industry: Blast furnace (stack/bosh), Hot blast stove (checker bricks), Casting ladles.
