Flow steel bricks refer to hollow refractory bricks that are laid in the grooves of the ingot casting bottom plate to connect the flow steel bricks and the ingot mold, commonly known as soup channel bricks. Mainly used to reduce the resistance of molten steel flow and prevent steel leakage. The main characteristics include high temperature pressure resistance, wear resistance, good fluidity, easy installation and good fire resistance.

Classification and application:
1. Clay flow steel brick‌: This is the most basic type of flow steel brick, made of ordinary clay. Although the price is low, it is relatively poor in fire resistance and service life, and is suitable for some small steel mills or temporary use scenarios‌.

2. High aluminum flow steel brick‌: This flow steel brick contains a high aluminum content, has excellent fire resistance, and can remain stable in high temperature environments. It is often used in large steel enterprises, especially in steelmaking processes that need to withstand high temperatures for a long time‌. ‌

3. Corundum flow steel brick: has extremely high hardness and is suitable for steelmaking environments that require high wear resistance.

Application

Flow steel bricks are widely used in flat plate casting of various steel grades, including stainless steel and various alloy steels. Its application areas also include runners in casting production, aluminum electrolytic cells and smelting equipment. In order to extend the service life of flow steel bricks, regular inspection and maintenance are required, including cleaning, repair and replacement.
