Bauxite Bricks

Bauxite bricks are manufactured on modern hydraulic presses with selected bauxite raw materials from overseas and with a defined bonding and grain matrix. A range of bauxite bricks is manufactured with specific properties, fine tuned to the area of application by the use of additives (e.g. chemical bonding) and precisely coordinated firing programmes.

The main areas of use for bauxite bricks are for covers of electric furnaces and ladles, as well as for transport vessels and mixer containers for raw iron. Bauxite bricks with 50 % to 85 % Al₂O₃ content are also used in certain areas in cement rotary kilns. Special phosphate bound (aluphobe) bauxite bricks from selected raw materials and additives are used in aluminium melters and in particular for the melter bath.
