There is provided a twin-belt casting machine which prevents an uneven cooling condition between the top surface and the bottom surface of a slab between a pair of endless belts disposed vertically. The twin-belt casting machine 1 comprises a pair of rotating belt units 3 including respective endless belts 2 and arranged up and down so as to face each other, a cavity 4 formed between the pair of rotating belt units 3, and cooling means 10 which is arranged inside the rotating belt unit 3. The twin-belt casting machine 1 continuously casts a slab S as a metal liquid is supplied in the cavity 4. The twin-belt casting machine I further comprises distance adjusting means which is arranged inside at least one of the pair of rotating belt units arranged up and down so as to face each other, and which moves apart or closer the endless belt relative to the slab S in accordance with a part where the slab and the endless belt become distant from each other.
La présente invention se rapporte à une machine de coulée à courroies jumelles qui élimine le refroidissement inégal d'une dalle entre deux courroies sans fin disposées à la verticale. Une machine de coulée à courroies jumelles (1) comprend deux parties de courroie rotatives (3) respectivement pourvues d'une courroie sans fin (2) et opposées verticalement l'une à l'autre, une cavité (4) formée entre les deux parties de courroie rotatives (3), et des moyens de refroidissement (10) disposés dans les parties de courroie rotatives respectives (3). Dans la machine de coulée à courroies jumelles, un métal en fusion est acheminé dans la cavité (4) et coulé dans une dalle (S) en continu. Des moyens de réglage de distance destinés à rapprocher la courroie sans fin (2) de la dalle (S) ou à l'en éloigner en fonction de la distance de séparation entre la dalle (S) et la courroie dans fin (2) sont prévus dans au moins une des parties de courroie rotatives (3) opposées verticalement l'une à l'autre.
