Abstract (en)
[origin: EP0736350A1] Casting device for a metal strip (9) where the solidification is effected by passing the molten metal between two counter rotating rolls (1,1') on horizontal axes. The rolls (1,1') are cooled by the internal circulation of a cooling fluid and the roll gap defines the casting space (2) for the molten metal. The outer surfaces (3,3') of the rolls have a specified roughness. The casting space (2) is rendered inert by blowing a given quantity of a gas or gas mixture across a cover (10) covering the casting space (2). The camber of the rolls (1,1') is regulated by changing the quantity of injected gas and/or the nature of the gas or the composition of the gas mixture, at least around the surface of each roll upstream of the contact zone with the molten metal. Also claimed is device (14,15,16) for blowing the gas and a system (7,18,19,20,21,22,22',23,23',24,24') for modulating the quantity of gas injected and/or the nature of the gas or the composition of the gas mixture. The gas mixture used may be a mixture of nitrogen and argon.
