First, the long side clamping force releasing cylinder 9 having a lock mechanism for releasing the clamping force is operated to the pushing side,
The clamping force of the buffer spring 7 is released. Next, the thickness changing hydraulic cylinder 8 is operated on the pushing side to widen the interval between the long side frames, the first short side frames 2 and 3 are removed, and the short side frames 10 having different thicknesses are inserted between the long side frames. . Next, the thickness changing hydraulic cylinder 8 is operated to the pulling side to set a predetermined long side frame interval. Subsequently, the clamping hydraulic jack 6 is operated to the pushing side to contract the buffer spring 7 and set the clamping force. Further, the clamping force is locked by setting the hydraulic pressure of the long side clamping force releasing cylinder 9 having the locking mechanism to 0. Next, the clamping hydraulic jack 6 is operated to the pulling side to retract the rod of the hydraulic jack 6.

This will be described with reference to FIG. The fixed frame 1 and a pair of short-side frames 2 and 3 provided on the fixed frame 1 are fastened by a fixed-side long-side frame 4 having one side fixed to the fixed frame 1 and a free-side long-side frame 5 having one side movable. In the continuous casting mold having a variable thickness, the free side long side frame 5 and the fixed side long side frame 4 are provided with a hydraulic jack 6 and a buffer spring 7 as a long side clamping device, a thickness changing hydraulic cylinder 8, and a lock. It is supported by a long side clamping force releasing cylinder 9 having a mechanism. The lock mechanism in the cylinder rod portion 11 of the long side clamping force releasing cylinder 9 having this lock mechanism is a bear lock mechanism here. This is composed of a cylinder rod portion 11 and a sleeve 12, as shown in FIG.
It is in the state of a tightening spring, and mechanically fixes the cylinder rod 11 at any position of the stroke. When hydraulic oil flows between the sleeve 12 and the cylinder rod 11, the sleeve 12 expands in the circumferential direction and the sleeve 12 expands.
A mechanism is provided in which the interference between the cylinder rod 11 and the cylinder rod 11 is released to provide clearance for the cylinder rod 11 to stroke with minimum resistance.

遠隔操作で、しかも短時間に行う事が出来る。As a result, even if an accident such as a pressure drop in the hydraulic system occurs, if the pressure in the sleeve 12 decreases, the lock force is automatically recovered and the lock force is maintained. Therefore, even if an accident such as a pressure drop in the hydraulic system occurs, the long side clamping force is maintained and does not lead to troubles such as breakout. Further, according to the present invention, the release of the long side clamping force when the thickness is changed and the setting of the clamping force can be performed by remote control in a short time.
