Abstract
The solidification of the strip (9) is performed by introducing liquid metal between two horizontal rolls rotating in opposition directions (1, 1') which are cooled by an internal circulation of a coolant fluid. A casting space is defined between the rolls and their outer surfaces (3, 3') have a roughness. The casting space is blanketed by a cooling gas or a mixture of gases through a lid (10) covering the casting space. An adjustment of the crown or profile of the rolls (1, 1') is performed by modulating the quantity of cooling gas blown onto the rolls and/or the nature and composition of the gas at least in the vicinity of the surface of each roll (1, 1') upstream of its region of contact with the liquid metal (2).
