Funnel Refractory Brick with Fireclay and High Alumina Material
The Description:
Flow steel brick refers to the hollow firebrick that connects the steel brick and the ingot mold in the groove of the ingot bottom plate, commonly known as Tang Dao brick. Flow steel bricks are generally rectangular hollow clay bricks with various specifications (see figure). In order to reduce the resistance in the process of liquid steel flow and prevent steel leakage, it is required that the inner hole of the brick is smooth, the shape is regular and the joint is tight.
