Wind guide wall brick for pellet shaft furnace
The special shaped brick of semi-zircon wind guide wall is made of high-alumina bauxite clinker, mullite, kyanite, zircon sand, and bonding agent. After the granulation and powder making processes, the mixture is mixed in a certain proportion and then pressed into shape. High temperature firing has good resistance to high temperature, erosion and erosion. It is mainly used in the air deflector of pellet shaft furnaces in steel plants.
