High Alumina Material Casting Steel Refractory Brick
The Description:
Sleeve brick is a kind of flow steel brick used in the casting industry, widely used in various types of steel (including stainless steel, various alloy steel) flat cast steel, is built in the ingot bottom plate groove connecting steel bricks and ingot mold hollow firebrick. Ladle lining brick, curved lining brick, fired and unfired plug brick, cast brick, seat brick and sleeve brick of cast steel in ladle have high fire resistance, good crack resistance and strong erosion resistance. Regular appearance, smooth passageway, size, variety complete. There is no specific specification size, can be drawn processing production;
The production process of high aluminum sleeve brick is the same as that of high aluminum brick. A neutral refractory material with alumina content of more than 48% is made of high bauxite clinker and other raw materials with high alumina content
High pressure molding and calcination.
Flow steel bricks are generally hollow clay bricks with a rectangular shape and various specifications. 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. Refractory products for metallurgical casting steel are all kinds of funnel bricks, cast pipe bricks, center bricks, through flow steel bricks, single hole flow steel bricks, two, three flow steel bricks, flow steel tail bricks and ingot mold bottom bricks for all kinds of steel (including stainless steel, alloy steel) plate pouring.
