Beschreibung
Zusammenfassung:	The utility model discloses a casting alumina octagonal brick which comprises a square cylinder of a hollow structure, wherein edges on inner and outer walls of the square cylinder are all chamfered to form a cross section of an octagonal structure, the lower end part of the square cylinder is provided with a groove with a downward opening, and the upper end part of the square cylinder is provided with a protrusion corresponding to the groove in an up-down manner. The casting alumina octagonal brick disclosed by the utility model is reasonable in design and simple in structure; when casting alumina octagonal bricks are placed, the grooves of the octagonal bricks at an upper layer are matched with the protrusions of the octagonal bricks at a lower layer to play a good positioning role; and the casting alumina octagonal brick is safer and more reliable during placement.
