Introduction
General-purpose clay bricks are versatile refractory products manufactured from high-quality refractory clay and chamotte. Through high-pressure forming and firing at 1300–1400℃, the bricks develop a dense structure with good thermal shock stability and strong resistance against acidic slag and acidic gas erosion.Available in JH-PN40 and JH-PN42 grades with alumina content of 40% and 42% respectively. These bricks are widely applied as general linings for various industrial furnaces, kilns, flues and stacks, offering a cost-effective solution for moderate-temperature applications.
Key Advantages
01
Good Thermal Shock Resistance
Withstands rapid temperature fluctuations during furnace operations, preventing cracking and spalling under cyclic thermal stress.
02
Strong Acidic Slag Resistance
Resists chemical attack from acidic slag and acidic gases, ensuring reliable performance in acidic service environments.
03
Cost-Effective General Solution
Offers reliable performance at a competitive price point, making it the most widely used refractory product for general-purpose applications.
