A stopper body of refractory material and cylindrical shape having a first end (), a second end () and an intermediate zone () there between, with a bore () of circular cross section, extending from said first end () in an axial direction of the stopper body into said intermediate zone () towards the second end (), wherein the said bore being provided with an enlarged cross section (at) along at least part of said intermediate Zone ().

Stopper body

The invention generally relates to a refractory pouring tube for pouring a molten metal from one metallurgical vessel to another metallurgical vessel. The invention as well relates to a corresponding assembly, comprising such a pouring tube.

Refractory pouring tube with porous insert

An enlongated stopper device for flow-control of molten metal from a vessel, containing molten metal, said device comprising: a) a body () made of a refractory ceramic material, b) a bore hole (), having a longitudinal axis (A) and extending from an upper surface () of said body downwardly, c) a rod (), penetrating with one end () into said bore hole () and being fixedly secured within said body (), d) a sealing member (), being arranged within a space adjacent to or being part of said bore hole (), said space being defined at least partly by unlike surface sections () of said rod () and said body () respectively.

Elongated stopper device

A refractory shroud device having an internal bore for through passage of molten metal, said device comprising, a body defining at least a portion of said bore, and having sufficient length to allow an end thereof to become immersed under normal operational conditions, and operationally engageable with said end a replaceable segment defining outlet means in flow communication with said bore, the said component having an internal profile adapted to provide a predetermined control over the flow of molten metal from the device.
