High Alumina Runner Brick

Highumina Runner Brick refers to a type of refractory brick that is designed specifically for use in the runners and channels of metal casting systems, such as in foundries and steel plants. These bricks are made from high-purity alumina or high-alumina raw materials, which offer excellent heat resistance and thermal stability.

The purpose of High Alumina Runner Bricks is to provide a durable and heat-resistant lining in the runner systems, which transport molten metal from the furnace to the mold during the casting process. These bricks are exposed to high temperatures and corrosive conditions, and they need to withstand the thermal shock and chemical reactions that occur during metal casting.

High Alumina Runner Bricks are characterized by their high refractoriness, resistance to thermal spalling, and low erosion by molten metals or slag. They have good thermal conductivity to facilitate the efficient flow of molten metal. The bricks are typically shaped and sized to fit the specific runner system design and can be held together with mortar or other refractory materials.

The use of High Alumina Runner Bricks helps improve the efficiency and durability of the casting process, ensuring a reliable and consistent flow of molten metal through the runner system while minimizing the risk of erosion and damage.
