Claims

[Scope of Claim for Utility Model Registration] (1) An air cylinder for connecting a tundish immersion nozzle for connecting a immersion nozzle to a collector nozzle following a slide valve of a tundish, which has a cushion rod on a side of the piston different from the cylinder rod side. 1. An air cylinder for connecting a tundish immersion nozzle, characterized in that the outer surface of the cushion rod is square, and a cushion-side end cap is formed with a square recess into which the square cross section of the cushion rod is fitted. (2) In the air cylinder for connecting the tundish immersed nozzle to connect the immersed nozzle to the collector nozzle that follows the slide valve of the tundish, a hole with a square cross section of a predetermined depth is provided in the axial direction from the end cap side of the cushion rod. An air cylinder for connecting a tundish immersion nozzle, characterized in that the end cap is provided with a protrusion having a rectangular cross section that is fitted into the rectangular cross-section hole of the cushion rod.
