Abstract (en)
[origin: JPH01254362A] PURPOSE: To smoothly drive a continuously cast slab and to improve the quality of the cast slab by arranging light sensitive type sensors to each of just back of a mold and between the mold and a driving device, correcting the deviation of a course of the continuos cast slab and the time lag of behavior and executing the casting. CONSTITUTION: The light sensitive type diode line camera 5 is arranged just back of the mold 2 and also, the other light sensitive type camera 5a is arranged near the driving device 4 between the mold 2 and the driving device 4. Further, an evaluation unit CPU 6 is connected with a control unit 7 to the driving device 4. The movement of the surface of the continuously cast slab 3 drawn out from the driving device 4 is observed with the camera 5 just after drawing out and this course and the time behavior are accurately measured, and in the CPU 6, these measured values are composed with the information simultaneously observed with the camera 5a and the deviation of the moving of the slag 3 is corrected to control the driving device 4. The driving of the slab 3 is smoothened and the quality is improved with the accurate control.
