Abstract
A plant for the continuous casting of metal strip (13) between two, internally cooled, counterrotating rolls (1, 1') with horizontal axes, the surfaces (2, 2') of which define a casting space (3) which is closed off laterally by two refractory side walls (4, 4') provided with means for pressing them, at least intermittently, against the ends (5, 5', 5", 5'") of said rolls (1, 1'), and having a shroud (6) which overhangs the casting space (3), horizontal clearances ".epsilon." being provided between said side walls (4, 4') and said shroud (6), wherein said side walls and/or said shroud include means for reflecting, throughout the casting run, the radiation emanating from the portions (16) of said liquid metal (9) which lie in the immediate vicinity of said side walls (4, 4') back onto the surface (8) of the liquid metal (9) present in said casting space (3), preventing said radiation from penetrating said horizontal clearances ".epsilon.".
