    摘要： A continuous casting machine including a container (1) for accommodating a molten metal (7) and a nozzle (2) for supplying the molten metal (7) from the container (1). A pair of rotating rolls (3,4) cools the molten metal (7) to form a solidified shell (8,9) on the surface thereof and compresses the solidified shells (8,9) to produce a metal sheet (10). A number of bearing boxes (11,12) is disposed in a housing (14) for rotatably supporting the respective ends of the rolls (3,4), and a rigid member (32,33) is disposed between the bearing boxes (11,12) in the housing (14). A prestress or initial force is applied to the rigid member (30) through the bearing box (12). and a controller (100) regulates the rotating speed of a drive means (27) in order to control the separating force (P) occurring at a compression of the solidified shells (8,9) by the rolls (3,4). By controlling the separating force (P), a leakage of the molten metal (7) is prevented and a sheet metal (10) having a uniform thickness is continuously obtained.
