An installation for the continuous casting of metal strip (13) between two counter rotating rolls (1, 1') with horizontal axes. The rolls (1, 1') are internally cooled, with their surfaces (2, 2') defining a casting space (3) laterally closed by two lateral faces (4, 4') of refractory material with a means for flattening them, at least intermittently, against the ends (5, 5', 5", 5"') of the rolls (1, 1'). It incorporates a cover (6) overhanging the casting space (3), some horizontal clearance ( epsilon ) being between the lateral faces (4, 4'). The lateral faces (4, 4') and/or the cover (6) incorporate some means for reflecting, during the whole of the casting operation onto the surface (8) of the liquid metal (9) present in the casting space (3), the radiation issued by the portions (16) of the liquid metal (9) which are situated in the immediate neighbourhood of the lateral faces (4, 4'), thus ensuring that this radiation does not cross the horizontal clearance ( epsilon ).
