Abstract

Η εφεύρεσις δίδει ένα εγχύτη αερίου δια ένα δοχείο τετηγμένου μετάλλου, που περιλαμβάνει: ένα θάλαμο εισαγωγής αερίου που έχει μια θύρα εισαγωγής και μια θύρα εξαγωγής όπου η αναφερθείσα θύρα εξαγωγής έχει στερεωμένη αεροστεγώς επ' αυτής δι' ενός συνδετήρος εκκρίσεως υπό πίεσιν μία εξωθημένη ράβδο η οποία εκτείνεται σ' ένα άκρο εκκενώσεως αερίου του εγχύτου όπου η εξωθηθείσα ράβδος είναι κατασκευασμένη από ένα αδιαπέραστο ουσιαστικά πυρίμαχο υλικό και έχει τουλάχιστον κατά μήκος της μια αξονική εκτεινομένη δίοδο αερίου, όπου η δίοδος επικοινωνεί με το θάλαμο εισαγωγής αερίου και έχει τόσο μικρές διαστάσεις, ώστε κατά τη χρησιμοποίηση το τήγμα ουσιαστικά να μην είναι ικανό να εισέλθει εντός της διόδου ή εντός εκάστης διόδου, όπου η ράβδος και ο συνδετήρ εκκρίσεως υπό πίεση είναι τοποθετημένος εντός του πυριμάχου σώματος της υποδοχής του εγχύτου δια το άκρον εκκενώσεως της ράβδου. ωThe invention provides a gas injector for a molten metal vessel, comprising: a gas inlet chamber having an inlet port and an outlet port wherein said outlet port is hermetically secured thereto by a pressure release connector an extruded rod or which extends to a gas discharge end of the ingot wherein the extruded rod is made of an impermeable substantially refractory material and has at least one axially extending gas passageway therethrough, wherein the passageway communicates with the gas inlet chamber and is of such small dimensions that in use the melt is substantially unable to enter the or each passage where the rod and discharge connector under pressure is positioned within the refractory body of the infuser through the discharge end of the rod. oh
