Patent Searching and Data


Title:
貫流換気口を有する溶融金属収容構造体
Document Type and Number:
Japanese Patent JP2013512780
Kind Code:
A
Abstract:
Exemplary embodiments of the invention provide a molten metal containment structure including a refractory molten metal containment vessel having an external surface, and a metal casing for the vessel having an internal surface at least partially surrounding the external surface of the vessel at a distance therefrom forming a spacing between the vessel and the casing. The spacing includes an unobstructed upwardly extending gap that is vented to the exterior of the structure by upper and lower openings in the casing. A layer of insulating material is preferably positioned in the spacing between the internal surface of the casing and the external surface of the vessel, with the layer of insulating material being narrower than the spacing at least at upwardly extending sides of the casing, thereby forming the unobstructed gap. The vessel may be a metal conveying trough, a housing for a metal filter, a container for a metal degasser unit, a crucible, or the like.
