High Alumina Brick Refractory Product Used for Steel Making
The Description:
Casting steel brick is a kind of firebrick, which is hollow cylinder structure, mainly used for pouring and forming of molten steel or molten iron. The cast steel brick is made of clay, shale, coal gangue or fly ash as the main raw material, and the solid or hole rate is not greater than the specified value and the outline size meets the requirements of the brick.

Product feature:
The casting steel brick is used to guide the passage of liquid metal into the cavity. It is an essential part of the casting technology to prevent the steel water from flowing outside the middle injection pipe when the steel flow diverges. Poured steel bricks are generally clay.
(1) The cast steel brick has good high temperature stability and no peeling.
(2) Good thermal shock resistance, resistance to sudden temperature changes.
(3) High strength, erosion resistance.
(4) Cast steel bricks are resistant to slag corrosion and high temperature corrosion.
(5) Good thermoplasticity at high temperature, buffer thermal stress, less sticky slag.
