摘要： PURPOSE:To continuously control the optimum clamping force corresponding to variation of static ion pressure caused by changing width of a cast slab by detecting load of a tie rod and adjusting spring force of the tie rod with oil pressure in an unclamping cylinder based on this detected signal. CONSTITUTION:A long side clamping force is always detected with a load detector 11, and a pressure control valve 12 is controlled with computing elements 18, 19. In accordance with the variations of the static iron pressure and bulging force by changing width of the cast slab during casting, unclamping quantity with the hydraulic pressure in the unclamping cylinder 9 is continuously controlled to obtain the optimum long side clamping force F. Further, expanding force (f) caused by heat expansion is detected with the load detector 11 to obtain the long side clamping force F as the same. Further, an adjusting piece 14 is fitted during casting and control is executed at comparatively little unclamping quantity and at the time of washing, the adjusting piece 14 is removed and the necessary gap to the washing is formed at comparatively much unclamping quantity. By this method, the optimum clamping force corresponding to the width change of the cast slab can be controlled.
