COOLING MEDIUM SUPPLY AND REMOVAL APPARATUS FOR A ROTARY LEADTHROUGH, IN PARTICULAR IN A CONTINUOUS CASTING PLANT, OF A SUPPORT OR TRANSPORT ROLLER ROTATIONALLY SUPPORTED AT ITS END WITH BEARING PINS IN BEARING BLOCKS

摘要

A rotary transmission leadthrough is disclosed for the cooling water supply and discharge of a supporting and/or conveyor roll rotatively mounted on bearing blocks (11) by bearing pins (9) arranged at its ends, in particular in a continuous casting plant. In order to supply the cooling water into the centre of the supporting and/or conveyor roll (1), the rotary transmission leadthrough has on a covering plate (14) which frontally covers the bearing pins (9) two plug sockets (12b, 12c) in a header (12) for two adjacent stationary standpipes (18a, 18b) which are plugged into plug sockets (19a, 19b) of stationary inlet and outlet ducts (20a, 20b).
