Lining of heavy and framed brick walls for boilers, and other parts
Clay refractory bricks are divided into professional use clay bricks (including clay bricks for blast furnaces, clay bricks for glass kiln, clay bricks for hot blast stoves) and ordinary clay bricks.
2.Professional use clay bricks are divided into: ZN-45, ZN-40, ZN-36
Common purpose clay bricks are divided into: PN-1, PN-2, PN-3
