Clay architrave refractory bricks

Clay architrave bricks The shape of clay arched foot brick consists of a right angle triangle and two tilted angles with each other, the content of Al₂O₃ is generally 30%~40%, and the content of Fe₂O₃ is less than 2.0~2.5%. Clay arched foot brick belongs to weak acid refractory products, can resist the erosion of acidic slag and acidic gas, it is an important part of the arch type kiln roof masonry.   The shape of the clay foot of the arch brick consists of a right triangle and two tilted corners with each other as a residual angle, the content of Al ₂O ₃ is generally in the range of 30% to 40%, and the content of Fe ₂O ₃ is less than 2.0~2.5%. Clay footing bricks are weakly acidic refractory products that can resist the erosion of acidic slag and acidic gases.   Clay footing bricks are used for high temperature kiln vaulting, which is an important part of vaulting, and it has a decisive influence on the life of the kiln. Therefore, the arch needs to be able to withstand high…
