PURPOSE:To prevent deformation of castings and to perform reliable cutting of castings, by controlling the air pressure of an air cylinder to support and drive a cutting device to which a clamp for clamping castings is mounted. CONSTITUTION:After a molten metal 2 passes a casting mold 3, it is cooled, and it is fed downward by means of a pinch roller group 6. The metal is clamped by a clamping device 9 of a cutting device 8, and is cut by a cutting tool 7. The cutting device 8 is supported by an air cylinder 10 and is vertically driven, and is moved along a casting direction. The air pressure of the air cylinder 10 is controlled by an electropneumatic regulator 11. A speed control device 13 for a pinch roller 6 to control the speed of castings 4 is connected to the electropneumatic regulator 11 through an amplifier 14, and the airflow of an air source 15 is controlled and the air pressure of the air cylinder 10 is automatically controlled through a solenoid valve 12. Thus, the moving speed of the cutting device 8 is synchronized with a casting speed, and a change in a tensile force is prevented from production.
