Abstract:
A device for resetting opposite guide segments of a continuous casting or continuous casting and rolling plant in three different positions, the device comprising a hydraulic cylinder including means for connecting the hydraulic cylinder with one of the opposite guide segments; a double-acting piston displaceable in the hydraulic cylinder between three positions corresponding to the three different positions of the guide segments, and having a first piston rod provided on one side thereof and connectable to another of the opposite guide segments and projecting through a first end wall of the hydraulic cylinder; and means defining the three positions of the piston in the hydraulic cylinder and including a first inner stop surface formed by an inner surface of the first end wall of the hydraulic cylinder and defining a first position of the piston; a second inner stop surface formed by an inner surface of a second end wall of the hydraulic cylinder and defining a second position of the piston, and outer stop means located outside of the hydraulic cylinder and defining a third position of the piston intermediate between the first and second positions thereofwherein the outer stop means comprises a first outer stop arranged at a free end of a second piston rod provided on another side of the piston and projecting through the second end wall, and an annular piston displaceable in a cylindrical extension of the hydraulic cylinder along the second piston rod and having a first outer stop surface cooperating with the first outer stop to define the third position of the piston.
