A device in connection with a rotor ( ) for the treatment of a liquid such as molten metal in a reactor ( ) or similar structure. Gas and/or particulate material is supplied to the liquid, preferably via the rotor shaft ( ) and through openings ( ) from a cavity ( ) in the rotor. The rotor shaft ( ) extends up through the base of the reactor ( ) and is arranged so that it may rotate inside a stator pipe ( ) which extends up from the base of the reactor. The rotor shaft and the stator pipe extend through an opening ( ) in the lower side of the rotor ( ) and into the cavity ( ) in the rotor. Expediently, the rotor shaft ( ) is connected to the rotor ( ) via a fixing device ( ) inside the rotor cavity, while the stator pipe ( ) ends in the cavity ( ).

Rotor for the treatment of a fluid such as a metal melt

Equipment for continuous casting of strands of metals, preferentially ingots of aluminium. The equipment comprises a flexible casting mould 1 that may be rectangular with two side faces 4, 5 restrained against movement and two flexible side faces 2, 3. The flexible side faces are provided with a stiffening part 36 in their middle regions, that sustains such a rigidity that the shape of the side faces in said regions are substantial constant as the side faces are bowed. The restrained side faces 4, 5 may have a stiffening part that passes lengthwise through the side face and possibly through the adjacent corners. This will have the effect that the flexible faces will behave as rigid affixed in their ends. The stiffening part 36 of the flexible side faces is attached to drag beams 6, 7 in an actuating mechanism 43. The actuating mechanism comprises pull/push bars 14, 15, 16, 17 that via link arms 23, 24, 25, 26 are connected with swingable force transmitting plates 27, 28 swinged by means of an actuator. The actuator may be provided with an external or an internal position sensor, and by means of a PLC program and a servo valve the flexure may be controlled according to a pre-defined scheme of flexure. The outside of the casting mould may suitable be provided with a simplified and improved cooling system comprising a coolant jacket 39, that may be made out of a plastics profile or an aluminium profile attached to the mould wall 42.
