POURING TUBE INSERTION AND REPLACEMENT DEVICE

摘要

The apparatus (1) according to the invention for the conveying and exchanging of a pouring tube (2) which is attached to a movable plate (3) sliding on guide rails (9) which can transmit an upward thrust, comprises a rocker arm (20) actuating a lever (26) in a manner so as to impart to the movable plate (3) a rocking movement about a horizontal frontal ridge of the movable plate which is engaged in the sealing zone surrounding a pouring opening in a reference plate. This rocking movement causes the movable plate (3) to be strictly parallel to the lower face of the upper reference plate (6), improves the tightness of the contact between the two plates and prevents any penetration of metal between the two plates.
