Abstract: The device is made up of two refractory plates, one of them fixed (15) and externally joined to the melt recipient and fitted with a hole matching the outlet nozzle of the recipient, and a sliding one (16) fitted with a refractory melted metal conveyance pipe, which sliding plate is fitted on a tilting frame (25) so that it is capable of sliding linearly. The sliding refractory plate (16) and the refractory pipe (5) are composed of two independent parts that are assembled upon a metal plate (11). The stationary (15) and sliding (16) refractory plates feature similar dimensions and structures and are fitted with a peripheral compression collar (2).
